Linlithgow is only 11 miles/18 km from Edinburgh International Airport .
By far the easiest option is to take the newly opened tram from the Airport to Edinburgh Park Train Station (about 10 minutes) and then change there for a train to Linlithgow. This costs around £9 for an adult with an all inclusive ticket and the whole journey takes around 30 minutes (allow extra time late evening or early morning for reduced train services).
There are no direct public transport links to Linlithgow from Edinburgh airport, however a dedicated airport bus service, Airlink Express, service 100, runs from outside the terminal building to Edinburgh city center (Waverley Bridge) Adult fares are £3.50 for a single, £6 for an open return and the journey takes an average 25 mins, tickets can be purchased from the kiosk at the bus stop. Once in Edinburgh city centre, there are direct bus and train links to Linlithgow.
Although there is no direct bus from the terminal, the number 38 which operates between Edinburgh-Linlithgow-Falkirk-Stirling does stop near the airport. Passengers must walk from the terminal towards the Hilton hotel, then continue on out of the airport complex, past a secure car park service, continue under the motorway bridge and then up some stairs and on to the motorway bus stop. This walk takes about 10-15 minutes and is not suitable if you have a lot of luggage, are disabled or a large group of people. There is a chance a taxi may run you there in a few minutes. The service is fairly regular (timetable - add/subtract about 5 minutes to/from ratho station for airport times) and runs from early morning until late at night and fares are very reasonble. Journey time to Linlithgow is about 45 minutes, although if using the bus to get TO the airport allow a lot of time for delays, especially in the mornings and other buys periods. It may be worth getting the service before the one you think will allow you extra time just to be sure!
At night/early morning the service may start or terminate at Linlithgow Cross, but for most of the day it will run through the main street of the town and out towards Falkirk.
Another option is to take the local 35 Bus from The airport to Edinburgh Park train station and then take the train from there to Linlithgow. Almost every train bound for Glasgow, (And every train bound for Dunblane or Sitrling) which stops at Edinburgh Park station will also stop at Linlithgow. The journey from Edinburgh Park to Linlithgow is non stop and takes around around 15 minutes.
Linlithgow is conveniently placed on the Central Scotland line, therefore benefits from regular trains to and from Edinburgh, Falkirk, Glasgow and Stirling. Trains to and from Linlithgow (LIN) station are operated by First Scotrail . The station only has two platforms, Platform 1 for eastbound trains and Platform 2 for westward trains.

Linlithgow is small enough to walk around. FirstGroup operate the 'Town Service' bus number L1, which loops round the town via the residential areas of Springfield, Braehead, Listloaning and Linlithgow Bridge. As it's a very small town, you won't find taxis available for hire (even outside the train station) and will need to call to arrange a pick-up in advance - but they can usually get to you in about 10 minutes. A search for "Linlithgow Taxis" will give you a few phone numbers, or just ask at a pub.
