The answer is the costs are offset by the Mexican Tourism. That's why they make it a hassle comming from Cancun to Belize. By offsetting the airline cost they get more tourism dollars on total. Makes little sense anyway even in the US. If a flights almost empty they will sell seats low to cover the expenses and not lose. If it's in demand it will never be discounted. I've found flights From LAX to Huston / Belize for 365.00 RT. Makes no sense. From Texas or Miami you will rarely find under 600.00. A friend just found one for 159.00 RT. from Texas. $$$$$$$$$ makes the world go round. Air Travel is one thing I wish was static. More people would travel more and the world would be a closer place.
