Iwish, if any switch hasn't been confirmed yet and they may well be evaluating a change, do you really think TCD reservations are going to say "well, it might be European or it might be Air Atlanta, but we haven't really made our minds up yet"? It is also eminently possible that the "nice young lady" - your phrase, not me being patronising - doesn't actually know if there is a change in the offing. I would suggest that you try to be less naive before jumping down other people's throats.
Latest news from European is rumblings of staff being asked to take pay cuts and company seeking new investors to replace the failed Bath/TCD deal.
