I've been traveling to Belize regularly for about 10 years and have flown both Maya Island Air and Tropic Air. First let me state that overall there is no difference the overall quality of service, nor the price for these two. Each covers some of the same routes, each has some exclusive routes. Both try to maintain a certain amount of flexibility in how they book and how many planes they fly on a given schedule, which *usually* works pretty well. The planes are almost all small prop planes, there will be no "service" on the flights, and in many cases the "terminal" buildings are tiny and with few services. Having said all that, Maya has gotten me all over Belize many times and I with the right level of expectations on MY part, I've not been disappointed.
If there was a 0 I would put that. We had a 1:30 flight booked with Maya, March 7, 2013, to go directly to Placencia. They oversold the flight, lied to us that "our plane was late," while 12 other people boarded the already late flight to Placencia. They made us wait another 1-1/2 hrs., before putting us on their smallest puddle jumper that then landed 2 other places before our final arrival in Placencia at 5:00, not 2:20 like we had booked. They took no responsibility & never compensated us for our troubles. I WOULD NEVER FLY WITH THIS AIRLINE AGAIN. Tropic Air is a far superior airline with awesome customer service.
