In Panama there are two airports receiving international flights: Tocumen International Airport (PTY) located in Panama City and where almost all international flights arrive and the Scarlett Martínez International Airport (RIH) located in Río Hato, Coclé where smaller aircrafts arrive and it’s close to the Pacific Coast beaches. But it’s most likely that your flight will arrive to Tocumen. Some international flights arrive to Isla Colón airport coming from Costa Rica and also the Panama Pacífico airport from Colombia. If you don’t have  ground transportation already booked, it’s always a good idea to count with reliable transportation as taxi drivers will charge at least 4 times more than the usual price.
