Back in the mid 90's a company in Cuba operated AN-2s on intra-island flights - probably still do. Bought a T shirt with AeroTaxi Cuba printed on it. Flew Varedaro to (IIRC) Trinidad on the south coast. About an hour each way.
They let pax sit in the right hand seat for a little while - I was lucky enough to get the RH Seat descending back into Varedaro on the return leg. Part of the 'enjoyment' was to fly low level off shore down the peninsula which was interesting. Kept sitting there until what seemed like 1000' on final when the Co came and tapped me on the shoulder saying something along the lines of 'I need my seat now'...
