I am delighted by this thread. After one of them Amex adds I already realized that they were breaching Directive 2005/29. And yes, if we'd bring FB and/or Amex to court we would most likely win it. However. I don't know if ever a FT community managed to take a sue off, for obvious logisitic and trust reasons.
Wouldn't it be simpler if we let the European Comission do their work? Wouldn't they simply pick it up if they get enough complains? Perhaps a good idea to send separate complains for the Amex and the KL and the AF adds....
