Hmm, sounds like good ammunition in American Airlines’ complaint versus British Airways over allegedly keeping US reservation systems out of the UK market: the US Department of Transportation has responded to complaints by TWA and Aer Lingus that its system gave unfair prominence to United Air Lines flights by fining United $45,000; the Department found inaccurate and misleading data on international fares on the airline’s Apollo reservation system – but says the favouritism resulted from use of software and data supplied by British Airways.
