Thanks for the info
ASTechGuy! Here's to hoping web check-in now works for flights to Mexico! Curious.... how do they check your passport when using web check-in?
Finally, if I run into my usual experience of the website telling me to see an agent for check-in (hence the kiosks don't work either), what's the earliest an agent will check me in? If I show up to the counter at 12:30p, can the agent check me in for an 8:45pm flight? I just don't want to park and run into the airport for nothing.
