Getting between London's airports
If you have to transfer from one London airport to another, here are your best options
How can you get from one London airport to another?
The easiest way is just to take a direct National Express bus (Nationalexpress.com) for £15 to £30.
With the exception of Heathrow-Gatwick (£18–£55 by private transfer, depending on how many you stuff in the car [2–8]), taking a taxi or car service is prohibitively expensive (expect to pay £80–£140 or more). And it is barely faster than the bus, if at all.
Below are the general amount of travel time and ticket prices you can expect:
Connecting Heathrow to another London airport
- Bus: £22.50; 50-70 min. (Nationalexpress.com)
Connecting Gatwick to another London airport
- Bus: £22–£33.70; 3–3.5 hr. (Nationalexpress.com)
- Bus: £20–£21.50; 2.5–3 hr. (Nationalexpress.com)
- Train: £27–£30; 75 min. (includes 10 min./£2 for the Luton shuttle bus.]
Connecting Stansted to Luton airports
- Bus: £15–£16; 80–95 min. (Nationalexpress.com)
You can also always go into central London from one airport and then back out again to another, but that gets time-consuming—especially since no two airports use the same central London train station.
The National Express bus will be faster and cheaper, so just do that.
Theoretically, to connect Heathrow with either Stansted or Luton you could ride the Jubilee line from Heathrow to Baker Street then walk a few blocks to switch to an Easybus shuttle to Luton or Stansted for a total cost of £5–£16, but that would take a minimum of 1.5 to 2 hours. To me, the small savings would not be worth it.
