The a la carte test is in addition to the complimentary beverage service, which remains unchanged, and the existing Food on Board fresh service available on American Airlines flights.

A recent survey conducted by American showed 78% of respondents said they would be interested in purchasing individual items for sale onboard the aircraft.

The a la carte test will be available on selected Dallas-Los Angeles, Dallas-Miami and JFK-San Francisco routes through Sunday.

"American Airlines is engaging our customers through this one-week test to determine if they want a la carte snack items as part of our Food on Board program," said Tim McMahan, American's Manager of Menu Planning & Development. "Regularly testing food and beverage options in flight gives us the opportunity to obtain direct customer and flight attendant feedback regarding our Food on Board offerings."
