Reach the most distant destinations of your trip in Panama by plane could be a good idea. Some people once arrived at Tocumen Airport in Panama City decide to fly to Bocas del Toro or David to start their holiday.
There are 2 companies at the moment that provide national flights.
Copa Airlines connects Panama City to David directly through Tocumen Airport, so it's very useful for visitors arriving with international flights that don't need to change airport.
Check the maximum weight of baggage allowed.
