Even if they didn't -- airlines match each others' prices regularly. It's legal to match the price that someone else is charging; it's illegal to discuss that price with them in advance, before setting it (except where you have anti-trust immunity).
I'm not saying there's an antitrust case here. Instead, if they looked closely enough they might not like some of the results from these TATL partnerships and, perhaps, could start taking a different view of them.
