Flew back from ARN to LHR on the 779 10/3 and had chosen exit row seats 12A and 12C (A320) on a flight that appeared up until the day as not being that busy. Online checkin allowed us to confirm this at midnight the night before. The next morning we'd been kicked back to 22E/F on the app. I'm Gold and partner Bronze. Blocked seat had been shown between us previously (and many other rows).
Turned out the Club curtain have been extended from rows 9 to 12. The irony was that noone occupied rows 11 or 12. It was quite a novelty sitting in 22F, even if I am 6'4" tall. Thank goodness it wasn't a Neo!
