On the full flights CPH-FRA/MUC/VIE/ZRH and my regular FRA-LEJ/NUE I am getting op-ups basically every single time they say "Today's flight is fully booked, therefore we restrict the amount of carry-on baggage...". Out of about 40 flights this year, at least on a third of them. But NEVER on a long-haul.

On SK I did not get a single op-up once on shorthaul. Guess there are just so many EBG/EBDs on thr manifest while for the LHG flights, only very few SEN. And since I always buy last minute, I guess my ticket value is pretty high which makes a difference on LHG op-ups.

Did not have a single CU since 2017. But had a good run in 2015-2017.
