The best airline credit cards in 2026 earn miles on every purchase, come with perks like free checked bags and priority boarding, and offer valuable sign-up bonuses worth hundreds of dollars in travel. Whether you are loyal to one airline or prefer flexibility, there is a card that fits how you fly.
Best Airline Credit Cards for 2026
Chase Sapphire Preferred — Best for Flexible Travel Rewards
The Chase Sapphire Preferred is not an airline co-branded card, but it is the best travel card for people who do not want to be locked into one airline. It earns 3 points per dollar on dining and online grocery purchases, 2 points on all other travel, and 1 point on everything else.
The real advantage is transferability. Points transfer 1:1 to United MileagePlus, Southwest Rapid Rewards, British Airways Avios, Air France/KLM, Singapore Airlines, and others. You can book the cheapest option available across multiple airlines instead of being tied to one program.
The sign-up bonus typically lands around 60,000 points. The annual fee is $95.
Delta SkyMiles Gold American Express — Best Delta Card for Occasional Fliers
The Delta SkyMiles Gold Amex earns 2 miles per dollar on Delta purchases, restaurants, and U.S. supermarkets, and 1 mile per dollar on everything else. The main benefit beyond miles is the free first checked bag for you and up to eight companions on the same reservation — worth $35 each way on most Delta routes.
If you fly Delta 2-4 times per year with a checked bag, the free bag benefit alone covers the $150 annual fee (waived the first year).
United Explorer Card — Best United Card for Most Fliers
The United Explorer earns 2 miles per dollar on United purchases, restaurants, and hotel stays, and 1 mile per dollar elsewhere. The card includes a free first checked bag on United flights, two one-time United Club passes per year, and priority boarding.
The annual fee is $95 (waived the first year). For regular United fliers, the free bag benefit and club passes easily offset the fee.
Southwest Rapid Rewards Plus — Best for Southwest Fliers
Southwest’s system does not assign traditional seat classes — every seat is available if you have enough points. The Southwest Rapid Rewards Plus earns 2 points per dollar on Southwest purchases and 1 point per dollar on everything else.
The biggest perk is progress toward the Southwest Companion Pass, which lets one person fly with you free (only paying taxes and fees) for the rest of the calendar year and the following full year. This is one of the most valuable perks in travel rewards when maximized.
The annual fee is $69.
American Airlines AAdvantage MileUp — Best No-Annual-Fee Airline Card
The AAdvantage MileUp earns 2 miles per dollar on American Airlines purchases and at grocery stores, and 1 mile per dollar on everything else. There is no annual fee, making it a low-cost way to earn AA miles on everyday spending.
You do not get a free checked bag with this card, but the no-fee structure works well for infrequent American fliers who still want to accumulate miles.
Co-Branded vs. General Travel Cards
Airline co-branded cards are best if you fly one airline consistently and want the perks — free bags, priority boarding, upgrade priority, and companion certificates. General travel cards like the Sapphire Preferred or Amex Gold give you flexibility to book across airlines, which often means better award availability and lower redemption rates.
If you live near a hub dominated by one airline, a co-branded card often makes more sense. If you mix airlines based on price and schedule, a transferable-points card is usually smarter.
Maximizing Airline Miles
Use your airline card for all spending to accumulate miles, then book award flights during off-peak times for lower redemption rates. Partner redemptions — booking United flights with Chase points, for example — sometimes offer better value than booking through the airline directly.
Avoid redeeming miles for merchandise or gift cards. The redemption value is almost always lower than booking flights. Miles are most valuable as airline tickets.
What to Look for in an Airline Credit Card
The free checked bag benefit is often the most valuable perk. A $35 bag fee each way adds up to $70 per round trip — a single bag per round trip for two people equals $140, which covers most airline card annual fees by itself.
Also evaluate the sign-up bonus, the earning rate on everyday purchases, companion benefits, and lounge access. Higher-end airline cards offer Admirals Club, United Club, or Sky Club access — valuable if you travel frequently.
Bottom Line
For flexibility, the Chase Sapphire Preferred is the best travel card. For Delta, United, or Southwest loyalty, the respective co-branded cards deliver perks that justify their fees. If you are unsure which airline you will fly most, start with a flexible points card and consider adding an airline card later when your travel patterns are clearer.
