PS KLM-AirFrance, IME, are the world champions at losing baggage.
When I lived there, and used to fly to South America, we used to have a sweepstake as to whose baggage would not arrive, since there was almost always someone’s bag not arrive.
I still say, get a car, drive to Germany or Belgium. The faff will be less, and there’s no fixed flight times. Save the flying for the week long annual trip to the Alps or wherever.
G/L getting from home/office to an alpine resort with 4 hours. When I lived in Holland I could probably manage 30mins to Schiphol, 30min checkin/bagdrop, 30-60min security queue, 30min min before flight, 1hr flight, 1 hr to get bags, 1hr min to anywhere like the Alps near Geneva. If that’s not > 4 hours claimed for driving to Germany, then having to rebuild bike rather than put wheels back in is probably enough to tip the balance. All for 1 and a bit day’s riding to get the last flight back on a Sunday.
But then I know people who have got up at 4am, first flight to GVA, ski all day, taxi back to GVA for 9pm flight home. And said they’ll do it again. Expensive day out.
