Members of American AAdvantage recently began earning miles on British Airways flights beyond American’s U.K. gateways to destinations in the United Kingdom, Continental Europe, Africa, the Middle East and Asia.

British Airways Executive Club members, in turn, can now earn miles on American flights beyond six of American’s U.S. gateways at Dallas/Fort Worth, JFK, Boston, O’Hare, Miami and Los Angeles to cities in the U.S., Canada, Mexico, the Caribbean and Latin America.

The carriers will not codeshare on each other’s transatlantic services to London, but American will codeshare on British Airways’ daily nonstop between JFK and Manchester. British Airways will do the same on American’s flights.
