Pisa International Airport (PSA), also known as Galileo Galilei Airport, is a relatively small and efficient terminal, but in 2026, you should still plan to arrive at least 2 hours before a domestic or European flight and 3 hours before a long-haul flight. If you are traveling only with carry-on luggage and have already checked in online, 90 minutes might suffice during the off-season, but the airport can get incredibly congested during the peak summer months due to the high volume of low-cost carrier flights (like Ryanair). Security lines can be unpredictable, and because many gates require a bus transfer to the aircraft, the boarding process often begins earlier than expected. If you need to drop off a rental car, add an extra 30 minutes, as the rental car center is located slightly away from the main terminal and requires a short shuttle or a 10-minute walk. For those departing on international flights outside the Schengen Area, allow extra time for passport control, which can sometimes have significant queues during the morning and evening rush hours.
