Connecting in TGU or SAL or MGA
In looking at award flights from IAH-PTY, I'm seeing all kinds of options to connect in places like TGU, SAL, MGA, etc....since I wouldn't be in a hurry, I thought it might be fun to connect in one of these cities, particularly TGU with it's well-known "exciting" landing patterns. I'm also assuming a CPU would be MUCH easier from IAH-TGU than the direct IAH-PTY flight.
Has anyone had any experience connecting in these smaller Central American cities? For TGU, are transit passengers allowed to stay in the terminal and avoid customs or is everyone sent directly to customs first since I can't imagine there are many people connecting.
