Can anyone explain why travel to Cancun, especially flights BACK to the states (Chicago or Minneapolis in particular) take anywhere from 18 - 27 hours, or more, requiring a night somewhere (Dallas, Atlanta, etc)? It didn't use to be like this. you could get down there in 4 hours and back in 4 hours, or thereabouts. Now, it seems they want to punish the Saturday to Saturday trade, but Saturday to Saturday is how the hotels set up their packages. Please help!!
