Transport:

Most recommend arranging transport in advance; see the thread in limos, taxis, transfers here. The airport authorized taxis are charitably described by some as a "taxi mafia", and unless you know how to deal with this ilk avoid them. Uber/Lyft is not allowed to pickup at the airport, although they can dropoff.

N.B. Members are reporting lengthy delays checking in (high demand times suggest 2.5-3.0 hours prior to departure) and delays on arrival for immigration and customs, particularly during high traffic times / high season. This can vary according to demand - spring break, Christmas plan for long lines.

Travelers from the USA no longer need to complete an FMM form on arrival, just the passport and flight# is enough to get through immigration.
