Stansted sits about 40 miles north-east of central London, up the M11 in Essex. It's the furthest of the city's main airports, so plenty of travellers check the train first. One ticket on the Stansted Express looks reasonable. Then you multiply it by four, add a cab to Liverpool Street with all the cases, and remember the first train might not suit a 6 am flight.

That's where we come in. Our fares are fixed per car, not per passenger, so families and groups often pay less each than they would by rail. Add door-to-terminal service, a chauffeur who loads the bags and no platform changes, and an airport transfer Stansted trip with us starts to look like the easy choice.
