British Airways, Europe's third-largest airline, may begin to offer "all-premium" flights between the United States and continental Europe to tap growing demand from affluent business passengers crossing the Atlantic.

"The details are yet to be decided, but we will provide a premium product to the EU-US business market, operating on a point to point basis," BA spokesman Tony Cane has said in a telephone interview.

"The service will probably consist of business class and premium economy seats," Cane said. "It's unlikely to be a single class product."
