Hi! Me & my family are leaving in about a month to go to Cancun for my wedding. We are flying from SFO to Denver then have an hour & half layover in Denver before departing for Cancun (all flights are Airtran or Airtran operated by SW). I have read that in some cases passengers need to re-check their luggage in order for it to make it to their international destination- or is just returning not leaving? Anyone know anything about this?
I'm also assuming we will need to go through some sort of customs security check at Denver? It would be great to know if we do- I don't want to stock up on water & snacks for the flights in SFO only to have to throw them away at Denver if we need to go through security again. Muchos Gracias!!! =)
