I have perused the board for info about Maya Air. I see the weight restriction is 55 lbs. Does anyone know if that includes/excludes backpacks, etc, that would ordinarily be carried onboard a larger airline? The kicker is that we will have scuba stuff, some of it wet. So while it looks like a good deal relative to the bag drag, it might not be if we have to pay mucho dinero for extra weight. Ideas?
