Most of the Tropic Air and Maya flights from BZE to San Pedro hold 11 or 12 people (I think). Don't know how they get so much luggage on the planes, but nearly alway get all of it to SP with your flight. They do have some smaller planes ... for example, we took a side trip to Tikal a couple of years ago. On the return flight from Flores, we were treated to 4 place Cessna. Thought my wife would jump out of her skin when the pilot made a sudden maneuver to get a better view of a waterfall. Also, we took a 4 seat plane from San Pedro to Orange Walk on the way to Lamanai. Nice smooth flight very early in the morning. BTW, Orange Walk's "runway" (I was going to say "airport", but that would really be an exageration)looks more like a short straight dirt road in the middle of a cane field.
