Make, or have someone make, a reservation. Remember they stop flying to AC when night comes. Depending on how much baggage you (and the others on the flight to AC) have, your luggage may not come on the same plane that you come on. At Tropic Air you can wait in the waiting room. At Maya Island Air, you can wait on the large covered porch area. That's our preference, but we often take Tropic air because they seem to have a greater number of the larger planes, and we think we have a better chance of getting our luggage on the same plane that we are on. On the other hand, it's really nice sitting out on the porch at Maya Island Air, with something with rum in it in your hand, looking at the palm trees and chatting with others hanging out on the porch. Sort of gets you into the mood of the place.
In any case, the people you're dealing with are really, really nice.
