We too had been looking at flights from Detroit to Cancun..Jan thru March. They started out in the high $900's and we just kept checking everyday. Price came down to $462.00 pp, and like Shammy said, by flying on a Wednesday instead of Tuesday it dropped even more. Of course we booked that flight..however our friends who aren't retired and not as flexible are looking at high prices for a week in February and possible may not make it down this year if they don't get any lower...Keep looking and hopefully you'll hit on something
