American Airlines (search) on Thursday said it will begin testing onboard food sales to coach passengers in September on a handful of flights, including several in the Dallas and New York markets.

The world's largest carrier, a unit of AMR Corp. (AMR), said it will sell breakfast and lunch/dinner combination meals for $5 to $7 and snacks for $3. The meals include a sandwich or salad and a variety of prepackaged snacks.

American will also experiment with breakfast and lunch/dinner snack boxes for $3 to $5 on certain other flights during the last two weeks of September. Snack boxes will contain four to five prepackaged name-brand snacks.

As part of the trial, passengers on select flights between Dallas/Fort Worth and Seattle and between Nashville, Tenn., and Los Angeles will be able to choose from a variety of new free snacks.

American said it will continue offering free drinks on its flights and will consider rolling out the food sales on domestic flights based on feedback from customers and flight attendants.
