People who’ve been flying to Japan from Europe since the Air Route changes, how has it been ?

Hi everyone,
If all goes well (and that’s a long shot with everything that’s been going on for 2 years now) I am to go to Japan later this month or in early April and I was curious about your experience or your acquaintances’ regarding flights (especially departing from Europe). Since the air route was changed I haven’t been able to read or hear proper stories of people traveling to Japan. How has it been handled for you ? Did you have to change your tickets ? Did you originally have a direct flight which changed into connecting flights ? Was it cancelled ? Which company were you traveling with ? Which route did they take (southern route over the Middle East ? Or maybe another ?) How long did your flight last and so on …
I haven’t booked my tickets since my CoE hasn’t arrived yet because of the EMS / Japan post situation (And I thought my bad luck would be over with Covid “””ending”””)

I am also curious about Finnair which is usually one of the cheapest option while flying from Europe but I wonder which route they’re using to fly to Asia.

Any account of your experience, story, advice could be helpful.
