The airline with the best average grade is Ethiopian Airlines with 8.5/10.
The average flight time is 3 hours and 49 minutes.
This flight was just normal, due to the bad condition of the washroom.
On the other hand, most of the time the dimming function of the window is disable.
The plane was older than VT-ANA.
However, the meal was ok especially the curry chicken rice. The FA was nice and
greet before takeoff and after landing.
I would take AI if there are any special promote to Osaka or Seoul.
