After much good news - the airport is receiving some flights, LAN airline specifically says on its website that it has contingency plans - my godmother just e-mailed to say their flights were cancelled, and they're not coming. She said her daughter's flight on American was also cancelled, which means my MOH is most likely not coming either since she's also flying American (other BMs are on Copa which says it's all systems go starting tomorrow). They could fly to Buenos Aires and then to Mendoza and drive/take a bus (another 6 hours), but I understand why that's not exactly the most attractive option. I don't really understand why/how LAN specifically says that they will be operating flights with different routes - they have to stop in other Chilean cities first to do customs and immigration - and yet has cancelled this flight. American doesn't surprise me, they have no info on their website except to say that people can reschedule without rebooking fees.
I honestly this whole time haven't thought they wouldn't be able to come. All news was making it seem like by Thursday we'd be cutting it close but ok. And now of 8 international guests, 3 are confirmed not coming, and I can only imagine MOH isn't as well.
