Solo traveler enjoying Delta Sky Club vs United Club access – United MileagePlus vs Delta SkyMiles 2026

Delta Sky Club access vs United Club — one of the key 2026 differentiators in this head-to-head.

Qualification charts rechecked October 22, 2026 on united.com and delta.com. Dollar examples that neither airline publishes have been removed.

So the question every loyalty-program shopper is asking right now is: United MileagePlus vs Delta SkyMiles 2026 – which program wins?

United MileagePlus publishes PlusPoints and Complimentary Premier Upgrades, and both have been eligible on award tickets since February 1, 2026. MileagePlus Upgrade Awards still cannot be used on award tickets. Delta SkyMiles publishes a Companion Certificate on its co-branded cards and a first-bag benefit for the cardholder plus companions. Neither airline publishes a single dollar value for a year of flying.

Key 2026 Program Note: Beginning February 1, 2026, PlusPoints and Complimentary Premier Upgrades are eligible on award tickets for all Premier members. MileagePlus Upgrade Awards still cannot be used on award tickets. Delta Companion Certificates remain tier-specific (Platinum card = Main Cabin only; Reserve card = Main/Comfort+/First Class). Both programs use dynamic award pricing with no blackout dates on their own metal.

  • Travelers comparing upgrade awards, Companion Certificates, free checked bags, lounge access, and status paths

United MileagePlus vs Delta SkyMiles 2026 at a Glance

United MileagePlus and Delta SkyMiles are the two largest U.S. airline loyalty programs, each built around dynamic award pricing with no blackout dates on their own metal. Both programs emphasize status perks, co-branded credit cards, and partner redemptions, but they take very different approaches to delivering value in 2026.

United MileagePlus focuses on PlusPoints and Complimentary Premier Upgrades (eligible on award tickets for all Premier members as of February 1, 2026), United Club access on the published card and status rules, and Star Alliance partner redemptions. Delta SkyMiles counters with the annual Companion Certificate, free checked bags for the cardholder plus up to eight companions on every flight, and Medallion qualification through MQDs.

Key Card Benefits at a Glance (2026)

  • Companion / Upgrade Perk: United offers PlusPoints and CPU upgrades (now on award tickets); Delta offers the annual Companion Certificate (Platinum card = Main Cabin only; Reserve card = Main/Comfort+/First Class).
  • Free Checked Bags: United = cardholder + 1 companion (Explorer/Club cards) or Premier Silver+; Delta = cardholder + up to 8 companions (Gold/Platinum/Reserve cards).
  • United: Unlimited access with the $695 United Club Card or Premier Platinum+; Delta Sky Club = 15 visits base on Reserve card when flying Delta (unlimited after $75,000 spend) or via Medallion Choice Benefits.
  • Status Qualification: United = PQP + PQF (Premier Silver 5k PQP + 15 PQF or 6k PQP); Delta = MQDs only (Silver $5,000 / Gold $10,000 / Platinum $15,000 / Diamond $28,000).
Qualification checked October 22, 2026: Through December 31, 2026, United still publishes Premier Silver as 15 PQF and 5,000 PQP, or 6,000 PQP; Gold as 30 PQF and 10,000 PQP, or 12,000 PQP; Platinum as 45 PQF and 15,000 PQP, or 18,000 PQP; 1K as 60 PQF and 22,000 PQP, or 28,000 PQP. Every level also needs at least 4 United or United Express flights. Delta's Medallion overview lists $5,000 MQD for Silver, $10,000 for Gold, $15,000 for Platinum, and $28,000 for Diamond toward 2026 Medallion status. The Delta Reserve terms give 15 Sky Club visits per eligible card, with unlimited visits after $75,000 in eligible purchases in a calendar year. Basic Economy does not earn MQDs.

United and Delta do not publish a cents-per-mile price. Any cents-per-mile figure still printed in the tables below is an estimate, not an airline fare. Award prices on both programs move with demand.

Detailed Perk-by-Perk Showdown: United MileagePlus vs Delta SkyMiles 2026

This is where the real decision gets made. Below is a head-to-head breakdown of the seven biggest differentiators between United MileagePlus and Delta SkyMiles in 2026. Qualification numbers were read on united.com and delta.com on October 22, 2026. Neither airline publishes a cents-per-mile price, so this section does not treat a cents-per-mile figure as an official fare.

1. Upgrade Awards vs Companion Certificate

United MileagePlus: PlusPoints (40 upon reaching Premier Platinum; 280 more upon reaching Premier 1K, plus 20 more per additional 3,000 PQP beyond the 22,000 PQP needed for 1K) and Complimentary Premier Upgrades (CPUs) are eligible on both revenue and award tickets as of February 1, 2026. United's PlusPoints page is the source for the 40 and 280 deposits. Upgrades are not guaranteed.

Delta SkyMiles: The annual Companion Certificate is issued on renewal of the Delta SkyMiles Platinum card or the Reserve card. The Platinum certificate is valid in Main Cabin. The Reserve certificate allows Main Cabin, Comfort+, or First Class. The certificate covers the base fare; taxes and fees are still due. Delta does not publish a dollar value for a typical use.

2026 Winner: United for upgrade chasers who fly mixed award/revenue itineraries; Delta for families wanting a guaranteed companion seat without upgrade lottery risk.

2. Free Checked Bags & Priority Boarding

United MileagePlus: United Explorer or Club cards provide the first bag free for the cardholder plus one companion. Premier Silver and above extend this to the entire party. Priority boarding is Group 2 for cardholders and Group 1 for Premier members.

Delta SkyMiles: Delta SkyMiles Gold, Platinum, and Reserve cards (and Medallion status) provide the first bag free for the cardholder plus up to eight companions on every Delta-operated flight. Sky Priority boarding (Zone 1–3) is automatic for cardholders and Medallion members.

2026 comparison: Delta's published card benefit is a free first checked bag for the cardholder and up to eight companions on Delta-operated flights. United's published card benefit is narrower: the cardholder plus one companion on the Explorer and Club cards, unless Premier status covers the rest of the party. The dollar savings depend on the bag fee in effect on the day you fly.

3. Premier Status vs Medallion Status

United MileagePlus: Qualification requires PQP + PQF (Premier Silver 5k PQP + 15 PQF or 6k PQP). Benefits include PlusPoints, CPUs, and United Club access at Platinum+.

Delta SkyMiles: MQD-only thresholds (Silver $5,000 / Gold $10,000 / Platinum $15,000 / Diamond $28,000). MQD Boost from Reserve cards ($1 MQD per $10 spent) makes qualification easier for heavy card spenders. Choice Benefits (refreshed February 1, 2026) include increased travel vouchers and status gifting.

2026 Verdict: Delta’s MQD path is simpler for most domestic flyers; United’s PQP/PQF rewards higher spend and segments.

4. United Club vs Sky Club Lounge Access

United: Unlimited access with United Club Infinite card or Premier Platinum+. Guest fees apply for non-cardholders.

Delta: Reserve card = 15 visits per Medallion Year when flying Delta (unlimited after $75,000 spend + 2 guests). Medallion Platinum/Diamond can select unlimited access via Choice Benefits.

2026 Value: United offers more consistent lounge access for heavy travelers; Delta is stronger once the spend threshold is met.

5. Award Redemption Flexibility & Dynamic Pricing

Both programs use dynamic pricing with no blackout dates on own metal. United publishes Star Alliance partners. Delta publishes SkyTeam partners. Neither publishes a cents-per-mile average.

Compare award prices across both programs

With dynamic pricing, the only way to know which program is cheaper for your route is to look. Search award availability before you commit miles or transfer points.

6. Earning Rates & Transfer Partners

United co-branded cards earn 1–3×; Delta cards earn up to 3× on Delta purchases. United transfers to Star Alliance partners; Delta to SkyTeam and select others. United has a slight edge in international partner redemptions.

7. Trip Protections & Insurance

Both Reserve/Infinite cards include trip delay reimbursement ($500 after 6 hours), baggage delay, and primary rental car coverage. Benefits are nearly identical in 2026.

All comparisons use official April 5, 2026 rules and average cash fares. The next section dives into honest pros/cons and real-user results to help you decide which program wins for your specific 2026 travel pattern.

United Club access is a strong pro for international travelers in 2026.

Honest Pros & Cons + Real Results in 2026

United MileagePlus and Delta SkyMiles are both strong programs, but they excel in different areas. The notes below follow rules read on united.com and delta.com on October 22, 2026. Dollar totals that neither airline publishes are not repeated here.

United MileagePlus – Pros

  • PlusPoints and CPUs on Award Tickets: Since February 1, 2026, PlusPoints and Complimentary Premier Upgrades can be requested on award tickets. MileagePlus Upgrade Awards still cannot. United does not guarantee the upgrade.
  • Star Alliance partners: United's published partner list includes Lufthansa, ANA, and Air Canada. United does not publish a cents-per-mile value for those awards.
  • United Club access: Unlimited United Club visits are a published benefit of the United Club Card and of Premier Platinum and above, on the rules those pages list. Delta's Reserve terms use a visit cap unless the card's spend threshold is met.
  • Predictable PQP + PQF Status Path: Heavy spenders can hit Platinum or 1K faster through a combination of paid flights and card spend, with clear PlusPoints rewards at each tier.

United MileagePlus – Cons

  • Narrower free-bag rule for groups: The published United card benefit is the cardholder plus one companion, unless Premier status covers the rest of the party. Delta's published Gold, Platinum, and Reserve benefit covers the cardholder plus up to eight companions.
  • No Guaranteed Companion Seat: Upgrade awards are lottery-based and subject to availability; there is no equivalent to Delta’s Companion Certificate for a locked-in companion ticket.
  • Higher Effective Card Fees for Lounge Access: Unlimited United Club requires the $695 United Club Card or Premier Platinum status, whereas Delta’s Reserve card provides 15 visits at a lower entry point before the $75,000 spend threshold unlocks unlimited access.

Delta SkyMiles – Pros

  • Free checked bags for a group: Gold, Platinum, and Reserve cards provide the first bag free for the cardholder plus up to eight companions on Delta-operated flights. The cash savings depend on the bag fee for that trip.
  • Annual Companion Certificate: Issued on renewal of the Platinum or Reserve card (Platinum = Main Cabin; Reserve = Main, Comfort+, or First Class). Taxes and fees are still due. Delta does not publish a typical savings amount.
  • Easier MQD-Only Status Qualification: MQD thresholds ($5k Silver / $10k Gold / $15k Platinum / $28k Diamond) combined with Reserve card MQD Boost ($1 MQD per $10 spent) make Medallion status more achievable for card-heavy travelers than United’s PQP + PQF system.
  • Choice Benefits Refresh (February 1, 2026): Increased travel vouchers ($350 Platinum / $700 Diamond) and expanded status gifting provide measurable hard-dollar value once qualified.

Delta SkyMiles – Cons

  • Limited Sky Club Access on Base Reserve Card: Only 15 visits per Medallion Year when flying Delta; unlimited access requires $75,000 calendar-year spend. United Club access is more consistent for heavy travelers without the high spend hurdle.
  • Different partner network: Delta's published alliance is SkyTeam. United does not publish a cents-per-mile gap between the two networks.
  • Upgrade Lottery Risk: Complimentary upgrades are subject to availability and lower priority than United’s PlusPoints system, especially on popular routes.
Neither airline publishes a dollar result for a year of flying. Use the published Companion Certificate, bag rules, and Premier or Medallion chart for your own routes.

Couple choosing Delta SkyMiles for Companion Certificate and group bags 2026

Domestic families and East/Midwest travelers usually pick Delta SkyMiles in 2026.

Who Should Choose Which Program in 2026

United MileagePlus vs Delta SkyMiles 2026 comes down to one simple question: does your travel pattern align with United’s upgrade awards and international partner strength, or Delta’s Companion Certificate and group free-bag policy? The programs are close in overall value, but the winner for any individual traveler is determined by route concentration, companion count, and whether you prioritize upgrades or guaranteed companion seats. Below are the exact personas that see the strongest ROI in 2026, based on verified program rules and average cash fares.

2026 Traveler Personas – Exact Recommendation Guide

International Business or Upgrade Chaser (long-haul or premium cabin focus)

Choose: United MileagePlus

PlusPoints and CPUs are eligible on award tickets, and United's published alliance is Star Alliance. United does not publish a dollar advantage over Delta.

Frequent Domestic Family or Group Traveler (East/Midwest/Southeast hubs)

Choose: Delta SkyMiles

Delta publishes a Companion Certificate on the Platinum and Reserve cards and a free first checked bag for the cardholder plus up to eight companions on Delta-operated flights. Delta does not publish a dollar advantage over United.

Low-Volume or Occasional Leisure Traveler (fewer than 5 round-trips/year)

Skip Both or Choose: Southwest Rapid Rewards

Neither airline publishes a dollar result that says you should skip both. Southwest still publishes a Companion Pass. Checked bags are no longer free on every fare: Southwest’s fee chart charges Basic, Choice, and Choice Preferred fares.

2026 Net Value: Usually break-even or negative on United/Delta

West Coast or Hawaii-Focused Traveler

Skip Both or Choose: Alaska Atmos Rewards

Alaska’s Atmos Rewards Ascent Visa Signature card publishes a $99 Companion Fare, and Bank of America lists a $95 annual fee. Taxes and fees on the companion ticket still apply. That is a published West Coast and Hawaii option. It is not a dollar ranking against United or Delta.

2026 Net Value: Alaska delivers higher ROI on core routes

2026 Decision Rule for United MileagePlus vs Delta SkyMiles: Choose United if 50%+ of your travel is international or you chase upgrades and lounge consistency. Choose Delta if you fly domestic with companions or family and want guaranteed seats plus group free bags. If your travel is mostly Southwest metal or low-volume leisure, skip both and focus on transferable points programs like Chase Sapphire Preferred or Amex Platinum for maximum flexibility.

These notes follow the program rules read on October 22, 2026. They are not a dollar forecast.

Alaska Atmos Rewards vs United and Delta for West Coast travel 2026

Alaska Atmos Rewards often beats both for West Coast/Hawaii routes in 2026.

United MileagePlus vs Delta SkyMiles vs Alaska Atmos Rewards & Southwest Rapid Rewards 2026

Alaska publishes a $99 Companion Fare on the Atmos Rewards Ascent Visa Signature card (taxes and fees still apply) and Bank of America lists a $95 annual fee for that card. Southwest’s fee chart, for tickets on or after April 9, 2026, charges for checked bags on Basic, Choice, and Choice Preferred fares. Two free checked bags remain on Choice Extra and for A-List Preferred. A-List members and eligible Rapid Rewards cardmembers get the first checked bag free. Neither United nor Delta publishes a dollar value for a year of flying.

4-Program Quick Comparison Table (8 Round-Trips/Year with Companions)

Category United MileagePlus Delta SkyMiles Alaska Atmos Rewards Southwest Rapid Rewards
Free Checked Bags Cardholder + 1 companion Cardholder + up to 8 companions Cardholder + up to 6 companions First bag free for A-List and eligible cardmembers; two bags free on Choice Extra and for A-List Preferred

Status Qualification PQP + PQF (more spend/segment driven) MQDs only + MQD Boost (easier for card spenders) Flexible points (distance/dollars/segments – switch yearly) Points + segments (A-List 40k + 25 segments)
Annual net value Not published Not published Not published Not published
Overall 2026 Winner By Traveler Type International / upgrade chasers Domestic families / East-Midwest West Coast / Hawaii groups Pure domestic leisure
2026 Quick Verdict: United MileagePlus vs Delta SkyMiles 2026 is a near tie for most travelers, but Alaska Atmos Rewards wins for West Coast/Hawaii families (lowest fee + group bags + Companion Fare), while Southwest Rapid Rewards wins for pure domestic leisure with its Companion Pass. If your travel is 60%+ on one carrier’s metal, choose that program. For mixed or flexible travel, consider transferable points cards like Chase Sapphire Preferred or Amex Platinum instead of committing to a single airline program.

What changes on January 1, 2027

United posted this on October 13, 2026. Starting January 1, 2027, Premier qualifying flights go away. You still need at least 4 United or United Express flights. The PQP thresholds on that page are Silver 6,000, Gold 12,000, Platinum 18,000, and 1K 32,000. If you hold an eligible United card by December 31, 2026 and qualify for 2027 Premier status, United also lists starter PQP of 300 for Silver, 600 for Gold, 900 for Platinum, and 1,600 for 1K. The 2026 chart above is the one that still applies through December 31, 2026.

FAQ

Is United MileagePlus worth it?

It is the stronger published fit if you want Star Alliance partners and Premier status that still uses PQF plus PQP through December 31, 2026. It is a weaker fit if you mostly fly Delta routes or you want Delta's MQD-only chart. United does not publish a single cents-per-mile value.

Delta SkyMiles vs United MileagePlus: which loyalty program is better?

Delta publishes one qualifier, MQDs: $5,000 Silver, $10,000 Gold, $15,000 Platinum, $28,000 Diamond on the Medallion overview read October 22, 2026. United still publishes a PQF-plus-PQP chart for 2026, then a PQP-only chart starting January 1, 2027, with 1K at 32,000 PQP. Choose the airline you can actually fly.

How many Sky Club visits does the Delta Reserve card include?
