Hi Flying Hare,
with what you describe I would think twice. I know people who are doing commutes like you have in mind, but they are very dependent on flight schedules and rostering. My personal opinion is that in the long term, long-distance commuting only works OK from places like London, PMI, maybe the Canaries, where there are plenty of direct connections. (For any other place, one should live within a day’s drive so if all goes wrong, you can still jump in your car and drive to LUX.) I’ve seen people begging load masters, mechanics, colleagues obviously, and even ATC to expedite procedures so they could make the flight home from LUX.
It was worse of course when we had no MyID travel and every Luxair ticket had to be requested and booked the old-fashioned way. There’s less minimum transit time now to catch a flight home and tickets can be booked online at short notice.
We have a bunch of ID-deals nowadays with all kinds of airlines however those most useful like LH or KL are still out of reach and will probably never come.
Bear in mind too, that for the kind of commuting you have in mind you will most definitely need an apartment close to the airport as juggling the hotels will hardly work for you.
Sorry for sounding a bit pessimistic, still I hope this helps.
Cheers,
Rudolph
