Interesting how these play out. I think it's sounding more and more like the IB segments will be flyable. LA, probably not, but interestingly they haven't reissued the ticket after cancelling their segments, my e-ticket still has the LA segment LIM-SCL on it. Almost sounds like LA may have tried to get IB to also cancel their segments but IB declined.
Really wanting to see what happens when the first people try to fly this. I'd imagine right now the tickets are a mess and can't be checked in as they are, since the LA segments are still on e-tickets.
I'm not an expert on EU 261, but once we're inside that window, is there a way to force LA to reinstate the segment? Force IB to re-ticket us with the missing segment? Seems Fuyao provided a lot of great info above for those who want to refund, but curious to hear from some experts on how to handle it if we actually do want to fly, and assuming that the remaining segments remain intact to the window where EU261 kicks in.
