Well, I helped give a CL an OpUp the other day.
SWMBO and I were SYD-MEL on a 767 in 25A/B.
Checkin at the totem to discover we're in 26D/E or similar.
SYD J lounge dragon: "Must be an equipment change"
Me: "what, from a 767 to a 767??".
Dragon: "Sorry sir, best I can do if you want a window is 36J/K".
Me: "ok fine".
After a few mins I was actually quite annoyed at being bumped from my carefully selected seats, so I head off the QP service desk instead.
Nice QP Lady: "Must have been an equipment change"
Me: "Nope - try something new"
Nice QP Lady: "Let's have a look who is in 25A..... Oh, it's a CL"
Me: "Why the hell am I being bumped from my carefully selected seats to something worse, by a CL, when J is wide open??".
Nice QP Lady: "i do apologise air"
Me: "Not good enough, stick him in J, or if we have to be bumped, then we should be bumped up, not down".
Nice QP Lady: "You're right sir, here you go, 25A/B for you".... As she picked up the phone to the CL desk to let the CL know the bad news that he was now in 3A
