For December travel from Houston George Bush Intercontinental Airport (IAH) to Cancún International Airport (CUN), the best balance of price and convenience is typically early December (first two weeks) and mid-week departures (Tuesday–Thursday). Avoid the heavy travel window from about December 20–31, when airfare and hotel rates rise sharply and flights sell out.

Nonstop flights from Houston George Bush Intercontinental Airport (IAH) to Cancún International Airport (CUN) are the fastest and most convenient option in December, typically taking about 2 hours 40 minutes to 3 hours.
