London Aiports
London is one the most served destinations in the world. To handle all those passengers, the city hosts 5 airports; London City, Gatwick, Heathrow, Luton and Stansted (and 2 smaller ones without scheduled services). London also has one of the biggest public transport networks within its boundaries. That doesn't mean that you should consider changing from one of London's airports to another. Just avoid that! To comfort passengers while stuck in traffic jams, some buses even have toilets on board. That says enough. If there's no way to get around a change of airport; plan a couple of hours for that trip and enjoy sight seeing.
Amsterdam Schiphol Airport
Amsterdam Schiphol Airport is one of the biggest airports of Europe. It's modern and pretty well organised, although you might not have that idea if you are roaming around terminal H, the low budget terminal. It's as basic as it can be; no shops, no restaurants, no toilets, and planes have to be accessed by old fashioned stairsways. But hey, you want to fly cheap: suffer and smile then :) The accessablility of Schiphol Airport is excellent. Of course you can jump into a taxi, but taking a train from Schiphol's indoor railway station brings you often as quick to your destination, and way cheaper. Trains from Schiphol to Amsterdam, Rotterdam, The Hague, Utrecht and several other cities run around the clock.
