What I don't understand is this statement: > "Airlines have told Orbitz that a traveler caught on a hidden-city routing is subject to having his ticket voided without refund, the Internet travel company said today in a statement." How in the world can they ever prove this unless I as the passenger explicitly tell them that I'm on a hidden-city route? Surely, a simple "I was feeling too ill to catch the second flight, so stepped out" would be something they can't contest. I understand that as the seller they have the right to refusal passengers but it seems like their combative stance is akin to the music/movie industries attitude towards torrents. I would think that both Orbitz and United would be better off on-boarding an "if you can't beat them, join them" mantra. This whole episode could have been flipped on it's head if the headline read "Skiplagged officially endoresed by United and Orbitz". Imagine the number of passengers they'd attract! I'm assuming that the market for flights is demand elastic to some extent. This is anecdotal based on my own buying pattern though.
