My worst fear flying air transat was the seating. Overall it was not that bad. My hubby who is 6foot 4 was a little cramped but we have had worse.
A suggestion to others, PLEASE don’t recline. Our seats could not recline ( exit row) and you were in my space
We did have no entertainment system there or back. That was no fun. And there is no plugins for electronics when they die.
The only other issue was the app. It was incorrect for departure time coming home and was never updated. Could be an issue for people not using the transfers from the company.
At least they serve beverages. Bring food unless you want airline prepackaged over processed items.
