(Reuters) -Britain's competition regulator said on Friday five airlines, including British Airways and American Airlines ( AAL ), have offered commitments to resolve concerns over their agreement to cooperate on passenger routes between the UK and the U.S.

The group of airlines, including Iberia, Aer Lingus, and Finnair, agreed to give their competitors slots for take-off and landing at London airports on routes to and from Boston, Miami, and Chicago, the Competition and Markets Authority (CMA) said.    The five carriers together form the Atlantic Joint Business Agreement, which allows them to coordinate their transatlantic flights and make business decisions on prices and schedules.

American Airlines ( AAL ) and Aer Lingus did not immediately respond to Reuters' requests for comments, while the other three airlines did not immediately respond.
