Best Airline Credit Card — By Airline and Goal
The right airline card depends on which airline you fly and whether you want free bags, a companion pass, or transferable miles. Here are the actual numbers — no affiliate rankings.
There is no single best airline card. If you fly Southwest frequently, the Southwest Rapid Rewards Priority Card ($149/yr) offers 7,500 anniversary points and Companion Pass eligibility that can be worth $500–1,000+. For Delta flyers, the Delta Gold Amex provides free bags and 2× on dining and groceries. For flexibility across airlines, Chase Sapphire Preferred ($95/yr) transfers 1:1 to United, Southwest, British Airways Avios, Air France Flying Blue, and 11 others.

Co-branded vs. transferable miles: which is better?
Co-branded cards (Delta, United, American) earn miles in one airline’s program. Transferable cards (Chase Sapphire, Amex Gold, Capital One Venture) earn flexible points that convert to multiple airline programs.
| Factor | Co-branded | Transferable points |
|---|---|---|
| Best earn rate on that airline | ✓ 2–3× direct flights | Usually 1–2× |
| Free checked bag | ✓ Often included | ✗ Not available |
| Flexibility across airlines | ✗ One program only | ✓ 10–20+ partners |
| Value vs. cash | Typically 1–1.5c/mile | Up to 2c/point via partners |
| Best for | Loyal flyers with status | Occasional or flexible travelers |
The math on free bags: A $99/yr airline card that gives you a free first checked bag saves $35–40 per bag, per flight. One round trip with a checked bag = $70–80 in savings. If you fly 2+ round trips per year with a checked bag, the card pays for itself.
The Southwest Companion Pass — biggest value in airline cards
The Southwest Companion Pass lets one designated person fly with you free (just taxes) on every Southwest flight for the rest of the calendar year plus the entire following year. To earn it, you need 135,000 Rapid Rewards points in a calendar year — and points from welcome bonuses count.
Strategy: Apply for the Southwest Rapid Rewards Priority Card in January, meet the spending requirement ($3,000 in 3 months earns 60,000 points), and the welcome bonus alone gets you almost halfway to the Companion Pass. Add a second Southwest card and you can earn the Companion Pass from signup bonuses alone if spend requirements overlap.
The math: A Companion Pass used on 10 round trips at an average value of $200 per ticket = $2,000 in travel value from one card benefit.
Frequently asked questions
- Do airline miles expire? Most airline miles expire after 18–24 months of inactivity. Delta SkyMiles do not expire. Southwest Rapid Rewards points expire after 24 months without account activity. United MileagePlus miles expire after 18 months of inactivity.
- What credit score do you need for an airline card? Most airline cards require 670+ FICO. Premium cards (Delta Platinum, $350 fee) typically approve at 700+. No-fee cards like Delta Blue and AAdvantage MileUp can approve around 650–670.
- Can you use airline miles on any airline? Co-branded miles can be used for award flights on the issuing airline and its alliance partners. Delta miles book on SkyTeam partners; American AAdvantage miles book on Oneworld carriers like British Airways, Cathay Pacific, and Qatar.
- Is it better to get an airline card or a cash back card? For most people who fly occasionally, a flat 2% cash back card outperforms a co-branded airline card unless you check bags frequently. If you check 2+ bags per year or fly the same airline 4+ times per year, the co-branded card usually wins on total value.
