American Airlines AAdvantage credit card with Citi gives you the first checked bag free ($25 value). Also, if you’re on the plane ride, they will try and hand you a brochure with a referral code on there. Use it to apply online and get 10,000 additional bonus miles, than the typical 30,000 they give you upon your first $1,000 purchase in the first 3 months.
I failed to include my referral code, so they just credited me a bonus 10,000 points. I missed out on the two free admiral passes, but I don’t think I would’ve really utilized those anyway.
Also, up to 4 others in your party will get their first checked on baggage for free.
I’m going to use the card to purchase airline tickets. But my regular purchases, since I get 2% cash back, I prefer that over miles.
