Dot2Dot[1] was a demand responsive airport bus service and company operating in London, United Kingdom.

It started operations on 1 November 2007, after National Express rebranded the Hotelink business it acquired in April 2007.

[2][3][4] Dot2Dot operated a mixed fleet of Mercedes-Benz Sprinter and Volkswagen Crafter minibuses and carried passengers from London's Heathrow and Gatwick airports to any location in a defined area of Central London or Canary Wharf, and vice versa.

[5] On 18 July 2008, Dot2Dot withdrew the service to Gatwick Airport, though this was later re-instated.

[6] National Express announced in late 2008 that not having turned a profit, Dot2Dot would close in early 2009 if no buyer was found.
