Through March 31, purchase a full-fare Concord, First or Club World ticket with your British Airways Visa Signature card and you can take a companion with you for free.

And that’s not all. Every time you use your card, you will earn one Executive Club Mile for every dollar in purchases — and 5,000 bonus miles with your first purchase. You must be a U.S. resident to apply for the British Airways Visa. For details, call (866) 255-3428.
