This is utterly ridiculous. For there to be a contract, there must be an intention to enter into a contractual relationship. There is simply no contract here anymore than there would be contract if I invited a friend to come to dinner tonight. The only contract there is is between IB and your friend, not between BA and your friend. At best what you can have is a tort case for negligent misstatement but, as I said, I wish you good luck with that because this is no piece of cake and, moreover, the link you reference and the lounge directory is on the OW website so if anybody is making a negligent misstatement, this would be OW rather than BA.

But if you feel like wasting your time and money, feel free and, as you say, report back to us when you've done. Until then, allow me to regard the statements that you made in this thread as mere wind and I will wait for you to prove me wrong.
