YVR-YYZ-CPH return booked on a P fare. Needed to investigate the possibility of changing the return to a day later so first verify there is P space for flights I want, reach out to corporate agent (because I have to of course) and ask about it.

"The fee is $383, Mr. WTME"

"Good, do it." <------ BIG MISTAKE MADE HERE. I didn't ask for the itinerary and then went on holiday without reviewing.

I noticed I wasn't asked about seats so went to select seats only to find I had been booked on a V class fare. You can imagine my dismay. I looked at the itinerary and that's where I found that I actually paid a HUGE penalty that was offset by the obviously much lower fare.

Corporate agent now wants another $1000 to fix the issue because there is of course no P class available.

Anyway, the question I'm taking too long to get to; is that a really strange penalty fee? I don't know what to ask or look for to verify this so thought I'd start looking for data points in the community.

Cheers.
