Flying and Customs

We are flying in from Calgary, Canada on Oct. 7. Can anyone give us an idea of what we are going to endure as far as flights and customs are concerned?

If you are referring to tighter security now, or just general traveling between Canada and Mexico...things are pretty much the same except you need to be at both airports 3 to 4 hours prior to departure, no carry ons. On this in (PV) things are as before. You will need your passport to depart Canada and enter Mexico.
