I talked to a KLM manager when boarding in CPT two weeks ago.
"Seat choice" has not been implemented yet for the flights departing South Africa.
BUt it will be soon.
So enjoy the free emergency exits while they last (they are usually blocked in the Internet Check-in anyway but maybe they forgot).

I heard KLM even wants to start charging for the two-seaters at the back of the all-passenger aircraft.
Fifty bucks for "more privacy" or will it be $100 bucks (50 per seat) ???

And does this mean that all the two-seaters on board of the A332 will also cost 50 bucks. Or is it going to be free on this aircraft?
Very consistent indeed.
Consistently BAD if you ask me.
