Tocumen International Airport

The main airport is in Tocumen, about 24 km from Panama City, and its code is PTY. Known as the "hub of the Americas", it operates international flights to over 65 destinations in 30 countries. There are some 15 passenger airlines, the main ones being Copa Airlines and TACA. The journey to & from Spain (Madrid) is operated by Iberia, sometimes with a direct flight, and others with stopovers in San Jose, Costa Rica or Miami. Upon landing, entering the country is very slow (I pent about 2 hours between immigration queues and baggage scanning). Once in the street you have public buses and taxis (25USD) to get to downtown.

Tocumen is the biggest and most modern airport in Central America, with flights reaching several continents and it is now the end point of the world's longest flight -- Dubai to PTY. Arrivals, immigration, and customs is easy and straightforward. The terminal has a surprisingly large and upscale selection of shops and boutiques. Exiting the arrivals hall is orderly and not confusing; look for the official taxi stand; prices are set according to the zone you are traveling to, though they are higher than if you walk out of the airport and hail a taxi on the street. (You can also walk out of the terminal to the street and catch a bus, although buses now do not accept cash and ride cards are apparently not sold in the airport.
