chase has a spphire card that offers 25k for 3k spend I did this months ago and just now got around to transferring points. the points are totally seperate from the airline cards so you wont be disqualified from getting bonus points by having a UA or CO card....they do transfer into CO points at 1 to 1. I put 28k worth into my wifes CO account today...I also noticed they offered single day presidents club passes for 2500 points which would be good once they merge for *A lounges (I think) they usually give a year expiration on the passes...so thats one way to get into the lounge for points or cheap. Anyway if your into CO and UA then check out the Sapphire card at chase it can boost your points some...it also transfers into amtrak, British airways, marriott, hyatt, PC, and a couple of others. Or you can get a 25% bonus on travel booked with points through them so 28k points gets you a $350 ticket on whatever airline you like.
