Delta vs. United: Weighing the Pros and Cons

When flying basic economy, Delta typically offers a more favorable carry-on bag fee structure. In terms of alliances, United is a proud member of the expansive Star Alliance, which boasts 26 airlines, while Delta is aligned with the slightly smaller SkyTeam, which has 18 member airlines. For frequent travelers considering premium credit card benefits, Delta's top-tier card provides access not only to their Sky Club lounge but also to the American Express Centurion Lounges. In contrast, United's equivalent card offers entry solely to United Club lounges. Additionally, those looking to redeem points might find that United's award tickets are generally more budget-friendly compared to Delta's. Given these distinctions, travelers should weigh which airline best aligns with their personal preferences, travel requirements, and budget.

Airline Credit Card Showdown

Result for Most Valuable Airline Credit Card: It's a draw!

Both Delta and United extend credit card offers packed with benefits like checked bags. However, Delta's AmEx cards cover baggage for up to nine people on the same booking, whereas United offers this for just two travelers.
Each airline also presents premium credit cards featuring airport lounge access. Yet, Delta gains a slight advantage since its top-tier card also grants entry to Centurion Lounges.
For the occasional traveler, the United℠ Explorer Card might seem more attractive than the Delta SkyMiles® Gold American Express Card. This is because the United card presents two one-time United Club passes and a statement credit for Global Entry or TSA PreCheck. Conversely, with Delta's card, you'll need to spend $10,000 to receive a $100 statement credit.
In the end, it's almost a tie between the two airlines when comparing card benefits. The deciding factor? It comes down to your preferred airline and which credit card perks resonate most with you.

Airline Loyalty Programs Overview

Ease of Earning and Using Miles: Winner- United.
While both airlines offer robust mileage earnings, United stands out due to its extensive network of partner airlines. This means members have access to more flights and a broader range of destinations.

Delta's Loyalty Program - SkyMiles:

• Earning Mechanism: Delta rewards its members based on the ticket's pre-tax cost, rather than the distance of the flight. The rate of SkyMiles earned per dollar is contingent upon your membership level in their program.
• Partner Flights: For those flying on SkyTeam or other Delta partners, miles are accrued based on a percentage of the distance flown, adjusted by the ticket's fare class.
• Value: According to NerdWallet, a SkyMile is estimated to be worth 1.2 cents. However, it's essential to note that Delta doesn't have a fixed award chart. Instead, they price mileage flights based on demand, which can sometimes make it harder to maximize the value of SkyMiles.
• Redemption Tip: One way to make the most of your SkyMiles is through Delta's SkyMiles Deals. These periodic promotions offer discounted rates for award flights, sometimes as low as 5,000 SkyMiles for a one-way ticket.

United's Loyalty Program - MileagePlus:

• Earning Mechanism: United's flight rewards earnings mirror that of Delta. MileagePlus members earn redeemable miles determined by their elite status and their spending with the airline.
• Partner Flights: When flying with Star Alliance members or other United partners, miles are calculated based on a portion of the distance traveled and the specific fare class of the ticket.
• Value: NerdWallet values United miles at 1.2 cents each.
• Redemption Tip: A unique aspect of the United MileagePlus program is the "Excursionist Perk." This feature allows members to include a free stopover in a multi-city roun.

Comparing Extra Fees

Leading in Low Fees -  Delta Wins

When examining the extra fees of Delta and United, Delta slightly edges out United, especially in terms of baggage costs. Delta not only offers a consistent checked baggage fee regardless of when you pay, but they also don't charge for carry-on bags in their basic economy class. In contrast, United tends to have higher fees, particularly if you opt to pay for checked baggage upon reaching the airport.

Being aware of potential fees can ensure you're securing the best value when booking.

Delta's Fee Breakdown:

• Checked Baggage: $30 for the first bag and $40 for the second.
• Seat Selection (for basic economy fares): The cost varies.
• Change Fee (for domestic and U.S.-originating international flights): $0, except for basic economy fares.

United's Fee Breakdown:

Comparing Basic Economy Fares: Delta vs. United

Delta Stands Out in Basic Economy

When comparing Delta and United's basic economy fares, both airlines offer a range of restrictions, but Delta has a slight edge, especially with its complimentary carry-on baggage policy. In contrast, United charges even for carry-on bags under its basic economy category.

Another point to note: Delta's basic economy fare doesn’t grant SkyMiles or Elite Qualifying rewards. Hence, Delta's basic economy might be suitable for those on occasional trips, while frequent flyers should consider a cabin upgrade to earn SkyMiles.

Delta's Pet Guidelines:

• Fee: Delta has a straightforward fee of $95 per ticket for pet travel.
• Number of Pets: One pet per carrier is standard. Yet, two pets (between 10 weeks to 6 months of age) can share a carrier, given they fit comfortably.
• Types of Pets Allowed: Delta is relatively flexible, welcoming dogs, cats, and household birds on board.

United's Pet Rules:

• Fee: United charges $125 for each pet journey. An extra $125 is added for stopovers longer than four hours within the U.S.
• Number of Pets: Traveling with two pets is permissible, but each requires its separate ticket.
