My son told me he found some info from a blog online and he got 50000 miles and a chase credit card successfully.

The following was what happened to me:

call 800-421-4655 [this is indeed the UA Mileage Plus phone number. clicking
http://faq.ua2go.com/display/4/kb/optional/index.aspx?tab=opt1&opt=1&r=0.805535]

provide ur Mileage Plus Number [US frequent flyer number] and ur zip code

tell the UA rep u would like to apply for a Chase credit card

u would then be led to apply for the credit card online

it takes about less than 10 minutes cuz the rep reads the terms and conditions online

u would then be told ur application is approved and the card will be in mail in a day or two

u spend any amount of ur 1st purchase and get 50000 UA miles or 2 round-trip air tkts continental USA/Canada

No fee for the 1st yr and $50 for each additional yr

[u may also apply at www.united.com, but u get only 30K miles]
