Update on the United Visa. The 15,000 mile signup bonus is good. Very good. However, there is a targeted offer out there for 20,000 miles. Instructions on the mailing say to call 1.888.763.7377 or send back the form in the mail. You might call and try asking for it, even though it appears to be a promotion valid for those who receive the offer. The code on the bottom of the mailing is BUC11309, and the code on the form which is to be sent back to the bank is LAC23925. Offer expires 9/16/02.
