When Legend launched all-business class service from Dallas a few years back, American Airlines responded by reconfiguring some of their planes with all business class and then quickly drove Legend out of business. Now, British Airways is considering the same tactic: their CEO said on Monday that the airline is examining the move to compete with Eos and Silverjet. Granted, Eos’ service is not just about the configuration – but BA’s entry into the market would be a pretty big challenge to the upstarts. My guess? BA will never actually bother.
