City Airport Transfers
London City Airport Transfers are very popular among those who travel to Stansted or Luton Airport.
This is the airport for big fishes mostly and some of the ugliest rich bastards in the world. Still there are domestic flights which some of the mid-level mangers will use to travel to Glasgow, Ediburgh or Birmingham.
There is a taxi rank outside and is probably the busiest taxi rank you have ever seen with hundreds of taxis in a long, long cue.

It's very wise thing to do to order a taxi to London City Airport well in advance. You should always allow 5 to 10 minutes extra time and ask for a approximate time between your address and the London City airport as taxi can get stuck in bad traffic and you could miss your flight.
When booking a taxi from London City Airport to the City allow approx 20-30 minutes for the journey. When you ask the operator or a taxi driver he will be able to tell you rough time needed to get there.
