American Airlines is to become the first major US carrier to charge passengers to check in a first bag.
The new fee of $15 (£7.50) comes as US airlines struggle with soaring fuel costs and a slumping economy.
The airline says it will also cut a number of its domestic flights and get rid of older, fuel-guzzling jets.
International travellers will be exempt from the fee. American joined other US carriers last month in charging $25 for a second checked bag.
