I haven't booked any of these tickets as those were pretty much useless to me for various reasons, but I did receive a call from a friend telling me about the deal. So I didn't find out about this from Flyertalk first even though I am a frequent poster here.

Now given I have no interest in this, allow me saying something in all fairness: I think Mr. Guyster made a very good point. In order for Thai to be relieved of any responsibilities, Thai would have to prove that all 1,500 passengers entered the contract in bad faith, that is all of them know this was obviously mistaken. I will agree that most of if not the quasi-totality of the 1,500 passengers probably knew it was a mistake but the burden of proving it lies on the airline. So there is definite a chance that a court might rule in favor of the consumers rather than the airline. Personally, I wish to see the case to go to the court because it would indeed be the first modern legal case when a mistaken internet offer is made and I am very curious about the outcome. Depending on the ruling, it could have a significant impact on other western countries using similar court systems as well.
