Does Panama have a good domestic flight network?

I want to travel the country, but I don’t want to have to rent a car and drive around.

Panama has an excellent network of domestic flights, that can get you to virtually any part of the country cheaply and quickly.  There are more than three domestic airstrips around the country, including on many of the islands on the Pacific and Caribbean coasts such as the Kuna Yala territory and the Las Perlas archipelago.  This makes it very easy to get around by air, as Panama is not a huge territory.  There are several airlines that ply these routes, and the two main airlines that fly domestically are Air Panama and Aeroperlas.  The main hub is the Marcos A. Gelabert airport in the Paitilla neighbourhood of Panama City, also knows as ‘Albrook Airport’.  Not all destinations have daily flights, and some are only seasonal, so you should check ahead to plan your itinerary.  Finally, there are also companies that do charter flights, and many private airstrips around the country as well.

Is there only one international airport in Panama?

Do I have to fly into Panama City when coming from another country, or are there other airports that receive international flights?

While the Tocumen Airport in Panama City is definitely the main hub for international flights (and probably for cheaper flights as well), there are two airports in Panama receiving international flights, mainly via Costa Rica: Bocas del Toro and the Enrique Malek airport in David.  The David airport has been undergoing major expansions, and there is an active campaign to make it ready for international flights from the U.S.  in the coming few years.
