Booked two seats with good legroom together with my wife. They last minute placed me between two strangers. When we tried to change it they would only offer use worse seats or make us pay an additional 580$ each to upgrade to economy plus. No other options and 3 days before we leave so we can’t make any more plans.
We’ve had the displeasure of flying with Air France twice in two years and they pulled the same thing on us both times.
If you book specific seats with this airline, there’s a good chance you won’t get them so watch out.
