Good to know, I guess no training around just based aircrafts from private owners and bizjets?
Basle to my knowledge does not have any such restriction. They are a French airport anyway. As far as I am aware you can fly there without slot or anything. Also pricing is not outrageous, at least I never heard anything negative.
Geneva has slots but is also not beyond the pale if you don´t take handling, which you are not required to in small planes. I have not tried to fly there recently but hear that it is very well feasible.
Am I to assume those people are regularly using their microlight aircraft to cross international borders in Europe, which would be relevant to this discussion? Would (for example, using my proposed utilization from Germany) 75% of flights in those aircraft cross international borders? If so would they regularly fly within a large number of European countries? Is that what you are teaching them to do?
Well, I’m teaching them to fly according to ICAO airspace “regulations” on an international airport. They can fly anywhere in the world, but where they actually fly is up to them of course.
In practice most stick to Norway, Sweden and Denmark. Anything further requires additional days just to get there and back again. Luggage is severely limited with 450 kg MTOW and two on board. There is also language and more “aero-cultural” barriers. It’s easy to fly in Scandinavia, with any sort of airplane, and we have more than enough space. I would guess though, with 600 kg and more speed with the 915, longer trips will become more doable.

Geneva
Someone I know used to fly in to Geneva once or twice a year until a couple of years ago. The grass runway was in quite poor condition but the tarmac is available unless they’re busy
Last I checked, 2-3 years ago, Geneva was about €200, plus parking. Got to watch the parking costs – search here for Sion parking which makes the landing fee insignificant
