Decide on the best method of transport. Heathrow is accessible by bus, coach and train services and has good road links for driving. Taxis provide the most comfortable and convenient route, but are the most expensive method, whether using licensed cabs or a private minicab service. Take the Piccadilly Line on London Underground for the most cost-effective link from central London. There are three underground stations at the airport, one serving terminals 1 and 3 and one each at terminals 4 and 5. Tickets can be purchased at either the ticket office or electronic machines in any London Underground station. The machines accept cash and most major credit and UK debit cards. You can also use a pre-paid Oyster card.
Book your ticket in advance for a guaranteed seat and/or the best price on coach and rail services. National Express is the UK’s largest coach operator and operates hundreds of daily routes from destinations throughout the UK and links between Heathrow and Stansted, Luton and Gatwick airports. Thandi Coaches run an express service from destinations in the Midlands, The Airline connects Oxford with Heathrow 24 hours a day, seven days a week, and Railair connects Heathrow to Reading, Watford and Woking. The central bus station is located outside terminals 1 and 3 with free transfers to terminals 4 and 5.
Take the Heathrow Express from Paddington for the fastest link from central London. As of 2010 trains run approximately every thirty minutes from 5.10am until 11.25pm and take about 15 minutes non-stop. The Heathrow Express serves terminals 1 and 3 and terminal 5 direct. For terminal 4 change for a connecting train at terminals 1 and 3. Tickets can be bought in advance on the internet, at either the ticket office or machines on platforms 6 and 7 at Paddington Station, or on board the train.
Reserve your taxi in advance if taking a cab. Taxis stop conveniently outside each terminal in designated drop-off points. Licensed black cabs operate on a meter system and can be hailed on the street, but are best booked in advance via computercab.co.uk. Addison Lee is London’s largest licensed minicab service. Vehicles must be booked in advance, either by phone or on the internet, and are charged at a fixed fare..
