Commuting no problem on the 380. Of the daily departures there are 3 FO slots on 3 day trips (will be 5 for part of summer), 6 on 4 day, and 6 on 5 day. So the majority of trips are longish, most get back early, none too late for flights to France, and only 1 of the reports (2 in summer) isn't commutable from France on the same day

Might need a read up on the new Crew Members responsibilities under EASA and FRMS.
If your commuting in and operating say in the evening to HKG if something happened you might be in some bother....
