$3000=3000 points or miles
This is really not enough to be useful/helpful to get you on a flight. Usually, you'll need upwards of 50,000 miles to get tickets for both of you. Are you planning on using this card heavily to gain more points?

Also, there is a difference between cards that give you points (Citi, Diners Club) and cards that issue miles (Alaska Air, AA). Both have their pros and cons.
