just my experience with chase and their CC, i have opened a
10,000 mile united checking account, got miles
25,000 miles united CC, got miles
17,500 onepass checking account, got miles
20,000 second onepass checking, got miles
21,000 third onepass checking, denied, wait til 2009 to open
15,000 chase onepass CC, got miles and $150 credit, got coupon and club pass even after closing the account
Southwest CC, got 16 credits
Marriot CC, got all points, free room
and 15 month interest free credit card, saved about $2,000 in interest and counting

so chase has been good for me, i only have 2 CC with them and will probably open the 40,000 mile deal
