US Airways adds premium food option on international flights for $20

Looking to boost revenue and attract international travelers, US Airways on Wednesday began offering first-class style meals for coach customers on flights to Europe, the Middle East and South America -- for $19.99.

Travelers will have to order the premium meals at least 24 hours in advance, US Airways said. They can select either a vegetarian or chicken meal. Philadelphia's dominant airline said it would also offer free wine with the meals.

At the same time, the airline said it would no longer accept cash for on-board purchases on international or domestic flights.

US Airways last year collected $1.09 billion in "ancillary" revenue, money from non-fare items. That ranked the airline eighth in the world for such revenue.
