I used to travel fairly often between Salzburg and London Heathrow, which has very few direct flights outside of weekends in the ski season. One option was to book a through ticket on the Lufthansa bus Salzburg-Munich then fly, which meant of course that the bus journey had to have a flight number. I particularly loved that there was a pick up at the halfway point of Rosenheim in Bavaria, which means a lonely bus stop in a car park just off the motorway also got assigned an airport code.
Lufthansa at least used to operate a "flight" from Frankfurt to Cologne main railway station. This included flight attendants in the ICE train cars, and a luggage conveyor at the railway station
I’m not sure what kind of spam merchants operate the website “kiss & fly”, but none of the following claims [0] are true:
“IATA code – ZPR. Rosenheim Bus Station operates domestic and international flights. Friendly staff will help passengers with customs and passport control, checked and carry-on baggage. Lounges with comfortable seats, bars, restaurants, duty-free stores, free Wi-Fi will not let you get bored while waiting for your flight.”
