Bonus miles always trump non-bonus miles. But even triple miles don’t make British Airways a shoo-in for your next overseas flight.

Offer Details

Between January 5 and March 31, members of British Airways’ Executive Club can earn triple miles (or Avios, as they’re referred to by British Airways) for up to eight flight segments throughout the airline’s worldwide network.

Codeshare flights operated by American, Finnair, and Iberia with BA flight numbers between North America and Europe are eligible for the bonus.

Registration is required.

Deal or No Deal

Triple miles beat the alternative, to be sure. And unlike some recent British Airways promotions, the bonus applies to all mileage-eligible fares, not just higher-priced fares.

The downside of this promotion is that the bonus miles are in British Airways’ program, which charges onerous “fuel surcharges” for many award flights. And aside from any specific quibbles with Executive Club, most U.S.-based travelers are better served by participating in the program of a U.S. carrier.

For British Airways loyalists, this is a no-brainer. Register for the promotion and book your BA flights. Others should ask themselves whether earning miles in Executive Club makes sense not just for the next trip but for the longer term as well.
