I am plat, last week I flew economy flex ticket fare.
Before checking I was supprised to select the exit row seat because before it was possible with flex plus
I asked crew how much do they charge for the exit raw after getting the price about 85€ for 6h flight
As Plat I explained there is no charge before Check in and during check in why should I pay
after checking with the purser about 5 min the crew offered me the exit seat for free
If you are plat you are at home and feel’confortable
the exist seat it is the worest seat my advice keep the twin seat 47 on 777
on 380 exit makes sense for the single seat row 69 approx
