Most people arrive at Pisa for Florence. Be advised that if you are catching a train to Florence, the booking office (it's the Information Office) is to the right of the Arrivals Hall. Do not follow the signs for the trains, which take you way out of the airport building far left. Trains are not so frequent so don't get caught without a ticket if you are a hurry! Also, remember that your ticket needs to be validated before you travel by sticking it in one of the yellow machines on the platform. This is essential as you can be fined for travelling with an unvalidated ticket.
