I’ve been on the road recently. So:
1) The Billa Supermarket in Vienna International (Wien-Schwechat). It’s located on the arrivals level; walk out of customs, turn left, go past the McDonalds, down the long corridor, and turn left.
In addition to the usual supermarket stuff, it has cold shelves full of salads and sushi, an icebox full of smoothies, and a deli that makes sandwiches to order. All fresh and tasty, and less than half what it will cost at one of the overpriced eateries on the departure level or out by the gates. The only drawback is that there’s noplace to eat it, but this didn’t slow me down — I sat on the stairs outside, while everyone went by on the escalators.
2) The showers at Frankfurt airport. Terminal 1, Departure Hall B, outside security. Two each, male and female. Used to be 5 euros each though that might have changed. Nobody knows about these, which is a damn shame. If you’re travelling in Europe, you’ll have to spend some time in Frankfurt airport, so why not take the chance to freshen up?
3) The kids’ playroom at Budapest Ferhegy. Okay, I wouldn’t exactly call this a secret — it’s not hard to find — but it’s the best thing I’ve ever seen: a small indoor playground with a toy chest, free video games and a changing room. Weary parents and squirrelly kids alike will find this a blessed oasis. If only more airports had this!
