I ran across this offer from Chase Visa. Get their Signature card, use it once, and get 50,000 BA points--good for one economy ticket from the U.S. to much of western Europe.
British Airways Visa
And, if you charge $2000 to the card in the first 3 months you get another 50k miles. Use it to by a BA ticket before the end of the year and get $50 off the ticket. Charge $30k--get a free companion ticket good for 2 years.
