American Airlines said on Friday it would charge a USD$50 fee to check a second bag on flights between some cities in Europe, India and the United States.

Starting September 14, passengers on those flights will pay the new fee to check a second piece of luggage. The first bag is still free.

The airline industry, battered this year by sagging travel demand, has begun generating new revenue by charging fees for items and services that once were included in the price of a ticket. Most major US airlines now charge bag-check fees.

American said the fees would apply on routes to, from, or through India, as well as the Belgium, England, France, Germany, Ireland, Italy, Spain and Switzerland.
