Terravision (operated by Green Line) offer cheap buses from London to Luton Airport.
Bus 757 departs from central London at Victoria and stops at Marble Arch, Baker Street, Finchley Road, and Brent Cross tube stations before travelling to Luton.
The driving time on these buses is around 1 hour and 40 minutes from Victoria, depending on traffic and the time of day of your departure. Early mornings and late evenings mean faster journey times due to fewer cars on the roads.
Bus 757 to Luton Airport runs 24 hours a day, 7 days a week, including bank holidays. At peak times during the early morning, day, and late evening, buses run every 15 minutes. At other times, they run every 30 to 40 minutes.
Booking a single bus ticket from central London to Luton Airport costs £17.50. It is a much better deal to buy a return ticket, as the price is £19.00 if you return within 24 hours and £25.00 if you return within 3 months. That saves you up to £16.00 if you buy a return ticket instead of two singles. You should buy bus tickets online to guarantee a spot at a particular departure time. Otherwise you can buy them on board if the bus isn’t fully booked.
