Just because its called London Gatwick, doesn't mean its in London - its approx 30 miles to South London and 50 To Central London, Heathrow or LondonCity are better options......
I dislike Gatwick airport with a passion. Poorly designed with too many low budget airlines. Overcrowded with shops, shops and more shops! Always try to stay away from Gatwick if possible.
The bathrooms in the arrivals area (south terminal) are hands down the cleanest airportbathrooms i have ever seen. Looked like a bathroom in a 4 star hotel. Im still shocked!
Taxi tip. Never Ever take a taxi between Heathrowairport and Gatwick. Exorbitant price. Pure robbery. 160 £ .crazy.take the bus. Frequent service comfortable and MUCH cheaper.
Make sure you check visa requirements BEFORE reaching the airport and being told to go back to the embassy to sort it out and come back for a later flight.
Gatwick Airport is the eighth busiest airport in Europe and until March 2017 had the world's busiest single-use runway, with a max. of 55 aircraft movements per hour. It serves more than 200 destinations (more than any other UK airport) in 90 countries for more than 46 million passengers per year.
