Does the EC seat map adjust in size for each route?
I'm on an Economy Flex ticket originally in Row 18. When I got the bid up email I went to investigate as I booked this a while back and forgot where I was. It let me select row 12 on a 752 which according to the seat maps is in EC (i.e. blocked out middle seat like intra-EU J).
On the bid up offer it is showing EC and Saga as my bid up options even though I went in and out of the booking and the free row 12 seat selection held.
