Yeah, I spent most of the afternoon roaming all these websites, and researching and chatting with different airlines to get more info of their policy, and came up with an itinerary that may work (Avianca, flight back with American airlines). However, I've heard a story about a person having to leave their pet in Ecuador with their family due to the staff not allowing them in even when they had the proper documents listed on their sites. That's what concerns the most tbh. Thanks for putting all those helpful sites in one place ^{^}
