For most US travelers flying 4+ times a year on one airline, a $99-fee co-branded card pays for itself in waived bag fees alone. Pick the card matching your most-flown airline; don't chase signup bonuses.
The "best" airline credit card is almost always the one for the airline you fly the most. Here's how to do the math honestly.
The Quick Math
If you fly an airline 4+ times a year and check a bag each way, the typical $99-annual-fee co-branded card pays for itself just on waived bag fees:
4 round-trips × 2 bags × $35 = $280 in saved bag fees minus $99 annual fee = $181/year net — before any miles or other perks.
Cards by Airline (Mid-Tier)
| Card | Annual fee | Free checked bags | Other key perk |
|---|---|---|---|
| Delta SkyMiles Gold (Amex) | $150 | 1st bag free (you + 8 companions) | 20% off in-flight purchases |
| United Explorer (Chase) | $95 | 1st bag free (you + 1 companion) | 2 United Club passes/year |
| AAdvantage Platinum Select (Citi) | $99 | 1st bag free (you + 4 companions) | 25% off in-flight purchases |
| Southwest Rapid Rewards Premier | $99 | 2 bags always free (Southwest perk) | 6,000 anniversary points/yr |
| JetBlue Plus (Barclays) | $99 | 1st bag free (you + 3 companions) | 10% points rebate |
| Alaska Visa Signature (Bank of America) | $95 | 1st bag free (you + 6 companions) | Annual companion fare $99 + taxes |
Premium Cards (Worth It Only for Heavy Flyers)
- Delta SkyMiles Reserve ($650/yr) — Delta Sky Club access, companion certificate
- United Club Infinite ($525/yr) — full United Club access
- Citi Executive AAdvantage ($595/yr) — Admirals Club access
These pay off if you take 8+ flights/year on the carrier AND value lounge access at $30+ per visit.
The Hidden Value: Transferable Point Cards
Instead of locking into one airline, consider a card with transferable points:
- Chase Sapphire Preferred ($95/yr) → transfers to United, Southwest, JetBlue, plus hotels
- Amex Gold ($325/yr) → transfers to Delta, JetBlue, Air France, etc.
- Capital One Venture X ($395/yr) → transfers to most major airlines
Common Mistakes
- Chasing signup bonuses — useful once, but pick the card you'll actually keep long-term.
- Holding cards for airlines you don't fly — annual fee always loses to no annual fee in that case.
- Forgetting about authorized users — many cards let your spouse / kids share the free-bag benefit when booked on the same itinerary.
