London has six airports serving pretty much the entire world! Some airports are much easier to reach central London from, some only fly to Europe, some are just for budget airlines... it's worth weighing up your options before booking any flights. Take a look at our public transport page to figure out your best options for reaching central London.

London Heathrow Airport 

Heathrow is not only the largest airport in Europe, but the busiest airport in the world! It's very easy and cheap to reach the city centre from Heathrow, but it isn't served by budget airlines.

Train
The Tube (Piccadilly line) leaves all terminals very regularly and is only £3.10 for a single journey with an Oyster card (see public transport) for a single trip to Zone 1, where you can change to any other line to reach your final destination. It takes around 1 hour to reach central London.
The Heathrow Express to Paddington station is very fast (10-15 mins), but also very expensive at £21.50 for a one-way ticket (if bought online, £26.50 at the station). Bear in mind that you will most likely be taking the Tube to reach your destination once you arrive at Paddington!
There is also the Heathrow Connect to Paddington station which is slower but cheaper at £10.10 for a one-way ticket or £7.80 to Ealing Broadway station.

Bus (1 hour) 
Easybus have just started routes from Heathrow to Shepherds Bush station, with prices as low as £1 if you book well in advance!
National Express coaches to Victoria station are comfier, but are usually more expensive... if you're lucky and book well in advance you can get fares as low as £6.
If you arrive in the middle of the night, the night bus N9 runs to central London; fares are £1.50 with Oyster card or contactless card (see public transport).

Taxi (1 hour)
Expect to pay ~£50 for an Uber and much, much more for a cab hailed at the airport.
 

London Gatwick Airport 

Gatwick is London's second airport located to the south of the city, quite a few budget flights fly from Gatwick.

The journey takes 35-40 minutes. Tickets may be cheaper if booked well in advance.
The Gatwick Express to London Victoria station is more expensive (£19.90 one-way) and only cuts 5 minutes off the journey time so really isn't worth it!
