Best card for Southwest flights

Updated September 24, 2026 · from RightCard's verified card and merchant data

Yes. Southwest Airlines codes as a travel. Our directory files it under travel. The strongest option in our data is a card with a built-in Southwest Airlines rate: Southwest Rapid Rewards Performance Business Credit Card (4% here, a card benefit). Among regular travel cards, Chase Sapphire Reserve earns 3x points here.

Why the code decides, not the cart

Every card purchase carries a merchant category code (MCC). The store sets it once, for the whole store. Your bank pays a category bonus by that code, not by what is in your bag. That is why a cart full of groceries can still earn the base rate.

These are permanent card benefits in our verified data, not limited-time offers.

FAQ

Which credit card is best for Southwest flights?

Yes. Southwest Airlines codes as a travel. Our directory files it under travel. The strongest option in our data is a card with a built-in Southwest Airlines rate: Southwest Rapid Rewards Performance Business Credit Card (4% here, a card benefit). Among regular travel cards, Chase Sapphire Reserve earns 3x points here.

Do Southwest co-brand cards earn more on Southwest?

Yes. Their built-in Southwest rate is a card benefit and shows in the table when we have verified it.

Do bank offers apply here?

Often. Amex, Chase, Citi and Wells Fargo each run card-linked offers that rotate monthly and are targeted per card. They beat any category math when you have one. The RightCard app syncs yours and checks them at the moment you pay.

Where these numbers come from: RightCard's data pipeline re-checks each card's published rates weekly and lists a rate only after two independent sources agree. Merchant codes come from our merchant directory. If a card or store is missing here, it is because we could not verify it, not because we guessed.
