I am looking for a flight for June6th thru June 12 leaving STL to CUN and the cheapest i have been able to find is USA3000. But they only have the 6th open for departure and nothing for return home on the 12th.
But as i started looking around and doing some searching on their site and other sites they have flights still available but only when booking the hotel and air together.
My question is do they hold a certain amount of seats for people who book the hotel and air? Its makes sense since they would be making more money off of them.
Just wondering because the best i can find is 840 for 2 people round trip with 1 stop and usa3000 is like 200 bucks cheaper and is a nonstop flight.
I have looked on all the different sites sidestep kayak and went to Continetal United AA and Frontier and nothing comes close????
Any thoughts or info you could share?
