Lancaster has cctv payphone phone shopStansted, Stansted Airport, Round Coppice Road, Stansted, Essex, CM24 1SF.
To take advantage of the best prices you will need to prove you are not a business traveller, en route to the airport, so you will need to provide either your flight numbers or yr holiday booking reference. I don't think you will need to provide this when you arrive at lancaster station but you may be asked to give them on yr journey from the station to the airport.
Going to stansted airport on the train is great, you can sleep, read (even at night), play travel scrabble, or just stare out of the window... The other restriction to buying these inexpensive tickets from the station to the airport is that there must be at least two adults travelling together. But another great advantage is that children go free. All children under five go free, and then one child over five but under sixteen per adult travelling by train to the airport.
be sure to leave plenty of time to get to stansted airport early enough to eat, shop and so on, so check the times of trains from the station before you go. If you end up with time to kill at stansted airport you can always read or play a game again! As you have bought yr train ticket in advance, you don't need to fret about the opening times of lancaster station.
