Sure, but not all easa is the same. Better to check with your home country. I have some old chopper mates up in the belgrano who keep an eye on my stuff.
I have heard some of the 330 guys can struggle to get a lpc from their home country. Getting sim and a tre or whatever they are called now. I can only imagine getting one on the 350 could be an expensive event. Getting your easa 320 lpc out here is expensive too. Certainly a lot lot more than my one was in england. And getting a sandbag for the other seat?
Its just more sense to me to stay on the 320. The cost to change fleet could be invested in property which is more interesting than slogging back and forward to japan at night.
Alternatively go to China Southern where its just a bond.
