This is my primary card for buying airline tickets. (5 pts/$) I also use it for dining (3pt/$) & the 2% (till Dec 31) for everything else is nice. Each point used for airline tickets is worth 1.5 cents. (1 pt for 1$). Also, no FOREX charges. ^
I bought 2 tickets with my points. LAX-ZRH RT in late August & PIT-LAX (one way) for last month travel. I was short some points for the Zurich ticket so I paid a little over $200 extra. (it was a $900 ticket--decent for Europe summer).
I plan to keep this card even when the annual fee kicks in next year. I am quite pleased with this card. The one drawback is one can't do multi city on their booking engine but otherwise it is a great card.
