Florence Airport to Lucca

Scott,

According to rome2rio.com, you can take a bus by VaiBus that goes directly from the Florence Airport to Lucca. ( Line E1 Extraurbane)

Check the details here: http://www.rome2rio.com/s/Florence-Airport-FLR-Italy/Lucca

Click on the orange bus icon, you will get a new screen, then you can click on the schedules (hot pink bar on the right of the screen)
This will take you to a new screen but it's in Italian.
You just need to click on "orario" to download the bus schedule for line E1

Hope this helps!

EDIT: Roberto will probably have more information for you ;-)

EDIT#2: When you are on the rome2rio website, you will see a map with the bus' route highlighted.

It looks like the bus stop is outside of the airport next to the airport parking lot.
I'm pretty sure you can buy your bus ticket at the airport (newspaper or tabacchi shop) & ask where the bus stop is ("fermata dell'autobus?")

Click on the icon under "ORARIO" column (PDF file) for line E1.
It will download the timetable for the line Florence-Lucca
The airport stop is called: AEROPORTO DI PERETOLA - FIRENZE
This service is not available on Sundays and Holidays.

The stop I think is next to the gas station near the parking lot in front of the terminal. However confirm when you arrive at the airport with the information desk.
