I used Tempelhof for the first (and I guess last) time last week. It is wonderful - why are modern airports not like this? The history and architecture are fabulous of course but it also works incredibly well - admittedly having so few flights means nothing is really under pressure. As noted elsewhere public transport links are excellent one can be in the city centre within 15 minutes of walking off the plane. From the departure lounge to seat on the aircraft takes less than a minute. I guess it is an anachronism in the 21st century but it is sad to say goodbye to an airport with real character.
