AirlineRatings names 'most excellent' airlines for 2018
http://edition.cnn.com/travel/article/airline-excellence-awards-2018/index.html
I think that how spacious economy seats are is one of the most important factors to choose airlines when flying between long distance.
when you board an aircraft which has narrow seats in economy class, what happens?
First, it's difficult to go to toilets, when you are not seated on aisle seats.
Second, while eating inflight meal, it's difficult to make a way for passengers who don't sit on aisle seats and wants to go to washrooms.
Third, when neighboring passengers are so fat that parts of their bodies invade your area, it's nightmare.
Based on the ranking, I'd like to choose best airline for my trip.
