Cabin Classes

Comfort isn't one-size-fits-all in the skies. Some airlines focus on simplicity, while others expand options. Delta Airlines vs United Airlines take different paths in shaping their cabin classes—so what sets them apart?

⏩ Here's how Delta vs. United comfort is different for each cabin class:

1. Delta Basic Economy vs United Basic Economy

When it comes to value and convenience, Delta Basic Economy slightly edges out United Basic Economy for most travelers. Here's how:

Delta Basic Economy:

Delta Seat assignment is given at check-in, so you may not sit together.

No changes or refunds allowed, but you can enjoy complimentary snacks and drinks, plus Delta's entertainment options.

◈ You're the last to board and can't upgrade your seat, but you get a Main Cabin seat and Delta's usual service.

◈ Boarding: Zone 8

Fond Tip: Want more flexibility? Add perks like flight changes, carry-ons, seat selection, or upgrades to Economy Plus® or premium cabins.

United Basic Economy:

United Seat assignments are also made at check-in, and you may not sit with your group.

While airlines ticket changes aren't allowed, United offers a 24-hour cancellation window for a refund.

Basic Economy passengers enjoy free soft drinks and coffee but no in-flight entertainment. Like Delta, upgrades aren't possible, and you'll board last.

◈ Boarding: Group 6

2. Delta First vs United First class

Both Delta vs United First Class offer elevated experiences, but Delta Airlines First Class excels in its in-flight amenities and entertainment options, while United First Class provides excellent comfort and priority services with a touch of exclusivity.

Delta First Class:

Wider, spacious seats with extra legroom and Sky Priority benefits.

Enjoy Delta First class perks and personalized service with complimentary meals and drinks, including Starbucks coffee.

More flexible airlines ticket change policies with free cancellations on U.S. and Canadian flights.

Loyalty Programs

United MileagePlus offers more flexibility, more partner airlines, and an easier way to earn elite status than Delta SkyMiles. United's global partnerships give you more ways to use miles, while Delta's changes make earning status more expensive, pushing many travelers to United.

Delta SkyMiles vs. United MileagePlus

Both programs use a revenue-based earning structure for flights, meaning miles are awarded based on ticket price rather than distance flown.

Elite Status LevelDelta SkyMiles - Miles per $1United MileagePlus - Miles per $1
General Member5 miles5 miles
Silver / Premier Silver7 miles7 miles
Gold / Premier Gold8 miles8 miles
Platinum / Premier Platinum9 miles9 miles
Diamond / Premier 1K11 miles11 miles
  • Elite Status: Which is Easier to Earn?

Delta recently made Medallion status harder to achieve by requiring Medallion Qualification Dollars (MQDs) exclusively. United still allows travelers to qualify via Premier Qualifying Flights (PQFs) and Premier Qualifying Points (PQPs), making elite status more accessible.

Elite Status

Level

Delta Medallion (MQDs Required)United Premier (PQFs & PQPs OR PQPs Only)
Silver$5,000 MQDs12 PQFs + 4,000 PQPs OR 5,000 PQPs
Gold$10,000 MQDs24 PQFs + 8,000 PQPs OR 10,000 PQPs
Platinum$15,000 MQDs36 PQFs + 12,000 PQPs OR 15,000 PQPs
Diamond / Premier 1K$28,000 MQDs54 PQFs + 18,000 PQPs OR 24,000 PQPs

➔ Advantage: United MileagePlus – The ability to qualify through flight segments (PQFs) makes it easier for frequent travelers to earn elite status.

➔ Delta's Higher Spending Requirement – Delta's MQD-only structure makes it difficult for budget-conscious travelers to reach elite tiers.

Fond Tip: Miles & Cash: Travel Your Way

Pricing and Fees

Airfare isn't the only cost to consider when booking a flight—baggage fees, seat selection, and ticket change costs can add up quickly. When comparing United vs Delta, small differences in fees can make one airline a better choice depending on your travel needs.

  • Baggage & Seat Selection Fees
AirlineOne Checked Bag (Domestic)Carry-On (Basic Economy)Average Seat Selection Fee
Delta$35Free$14.17
United$35 (if added 24+ hours before departure)Not Allowed$15
  • Flight Change & Cancellation Fees
AirlineChange Fee (Economy & Above)Change Fee (Basic Economy)24-Hour Risk-Free Cancellation
DeltaFree for most tickets from the U.S. & CanadaNot allowed (only cancel with a fee)Yes
UnitedFree for most domestic & U.S.-originating international flightsNot allowed (must upgrade to Economy first)Yes

📌 Insight: Delta is the best choice if you're a casual traveler because of the included carry-on and fewer restrictions. But if loyalty perks and status matter, United's Basic Economy has more to offer despite its baggage limitations.

Who offers the best travel credit cards?

Delta cards offer better loyalty perks and lounge access, while United cards provide more flexibility and global reach. The best choice depends on your travel priorities.
