Given the post below, you'll realise we'll go to quite some lengths to get some peace on public transportation. So if you are like us, take this advice when flying to Europe:
Always fly from London City Airport in the middle of the day if you are going almost anywhere. The place is empty and comfortable, you can even enjoy breakfast at an empty bar with a decent drink and converse, gently, with the staff, who outnumber you. This may cost you an extra £100 on your tickets, but blimey it's worth it. You go through security in a jiffy, also by yourself. Terrific.
You'll fly Swiss, or Lufthansa or BA, the sandwich will be nice, the wine free, you probably stop off in Zurich. Zurich is an awful place but the airport is huge and also empty (see above). Whatever the extra time, who cares. Then, if you are flying like we were to Berlin, you fly to Tegel. Tegel is a very imaginatively designed airport with an arrival to exit space not much bigger than your front room and a baggage belt at each gate. You arrive, you pick up your bags, and you leave. You do not have to cross football pitches of shopping. There was no security (they are not breeding islamic extremists in Germany right now I suppose). So out you go and get your taxi right out of the exit.
The Germans were going to demolish the clever Tegel airport and build a brand new spanking Shonefeld, but this Westfield like adventure went tits up somehow, so use Tegel while you can.
