Best Airline Credit Cards of September 2026

The Platinum hits the airline-card sweet spot: an annual companion certificate on renewal that routinely returns $300 to $600 on a Delta Main round trip, against a $350 fee. The first checked bag is free for up to nine people on your reservation, and the June 2026 refresh added a free second domestic bag for the cardholder. Card spending also feeds Delta status, with a $2,500 MQD head start each year plus a dollar of qualification credit per $20 spent. It's for the Delta regular who wants premium perks without the Reserve's price.

United's 2025 refresh raised the Explorer's fee to $150, waived the first year, and stacked more than $400 in annual partner credits against it, spanning rideshare, United Hotels, Instacart, JSX, and Avis or Budget. The core perks stay: a free first checked bag for you and a companion, priority boarding, two United Club passes a year, and a Global Entry or TSA PreCheck credit. Card earning runs three miles per dollar on United purchases. It's for United flyers who will actually use a credit stack that now reads like a coupon book.

The Companion Pass, which lets a chosen person fly with you for just taxes and fees on every Southwest flight for up to two years, remains the most valuable perk in domestic travel, and the Priority's 10,000 annual qualifying-point boost is the fastest realistic head start toward the 135,000 points it takes. Since Southwest ended free bags for everyone in 2025, the card now carries that perk instead: first checked bag free for you and up to eight others on the reservation. A 7,500-point anniversary bonus claws back much of the $229 fee. It's for Southwest loyalists chasing the pass.

Alaska and Hawaiian's merged Atmos Rewards program kept the famous Companion Fare: spend $6,000 on the card in a year and a second traveler flies for $99 plus taxes and fees, from $23, on a paid fare, savings that routinely beat the $95 fee on one booking. The free first checked bag covers you and up to six guests on Alaska and Hawaiian flights when the airfare goes on the card, and oneworld partners widen where the points go. Card spending also earns status points with no cap. It's for West Coast and island flyers who bring someone along.

Now the default American Airlines card after Citi absorbed the rival Aviator Red in April 2026, the Platinum Select covers its $99 fee, waived the first year, with one round trip: the free first checked bag applies to you and up to four companions on domestic AA itineraries, easily $200 saved per trip for a family. Preferred boarding and a $125 AA flight discount after $20,000 in annual spending sweeten it. It's the workhorse pick for anyone whose home airport belongs to American.

The Reserve is the Delta loyalist's premium play: Sky Club access at 15 visits a year, unlimited after $75,000 in annual spending, plus Centurion Lounge entry when you book your Delta flight on the card. Its annual companion certificate is the strongest in the business, covering First Class round trips that can be worth $600 to $1,000. Credits for Resy, rideshare, and Delta Stays total up to $560 against the $650 fee. It's for frequent Delta flyers who'd otherwise buy lounge membership anyway.

Full Admirals Club membership, which sells for about $850 on its own, comes bundled into the Executive's $595 fee, making it the cheapest path to American's lounges for anyone who'd buy in anyway. The free first checked bag stretches to nine people on domestic AA itineraries, the most generous waiver here, and AA purchases earn 4x with Loyalty Point bonuses at 50,000 and 90,000 points each year. It's for AA frequent flyers who live in the Admirals Club.

The JetBlue Plus quietly pays for itself: a 5,000-point anniversary bonus offsets most of the $99 fee, the first checked bag is free for you and up to three companions on tickets bought with the card, and every JetBlue award redemption returns 10% of the points uncapped. Earning runs 6x on JetBlue purchases. For lounge seekers JetBlue now sells a $499 Premier card, but this is the value play. It's for East Coast flyers who treat JetBlue as their default.
