Lincoln Central has cctv payphone phone shopHeathrow, Heathrow Airport, Hounslow, Middlesex, TW6 1JHX.
To take benefit of the best prices you will need to prove you are a leisure traveller, on the way 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 lincoln-central station but you may be asked to give them on your journey from the station to the airport.
Going to the airport by train is great, you can sleep, read a book (even at night), play travel scrabble, or just gaze 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 grown ups travelling together. But another great advantage is that children go free. All children under 5 go free, and then one child over 5 but under sixteen per adult travelling on the train to the airport.
make sure you leave plenty of time to get to the airport early enough to eat, shop and so on, so check the times of trains from the station before you go. If you have spare time at heathrow airport you can always read a book 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 the station.
