Taking an easyBus coach is the cheapest way to get from London to Gatwick Airport.
easyBus coaches depart from central London near Earls Court. The closest tube station to the bus stop on Lillie Road is West Brompton on the Wimbledon branch of the District Line.
The travel time is 1 hour, making it a fast trip to the airport. easyBus coaches arrive at Gatwick South Terminal first, then continue on to the North Terminal from there.
With single coach fares from central London to Gatwick starting at £2.00, easyBus offers the lowest fares around. That said, you sometimes get what you pay for. Buses are sometimes known to be late or not show up at all, so make sure to leave yourself plenty of time to get to the airport in case there are issues.
Coaches are relatively small with little storage space for luggage, so make sure to pack in as small a suitcase or bag as you can.
Be sure to print your ticket before you get to the bus stop, and arrive 10 minutes early to ensure that you get a place on the bus you booked. Tickets are valid for 60 minutes on either side of your booking, but you are only guaranteed a seat on the bus you purchased a ticket for.
NB: To get the best price on your easyBus tickets to Gatwick Airport, try to schedule your flights at off-peak times. Ticket prices tend to be lower very early in the morning, in the middle of the day, and very late in the evening.
