The Exito Travel site advises that "most airlines will demand to see a return ticket within the 90 day stay parameter, and if you don't have one, they will deny your boarding and you lose your ticket". Es verdad??
Since my intention is to stay permanently, returning to the States at 90 or 180 days only if the On-The-Ground investigation discloses that I am allergic to Cuenca, I plan only to buy the one way ticket and defer that $700 expenditure for three or six months or forever.
What can you tell me?
