I have a seat close to the back plane on the LH 572 flight. I called to ask if I could select a seat at the front of the cabin in the priority section, but they wouldn't do this for me.

As such, I can checkin 24hrs in advance and those seats will have opened up. I was also told that they only assign the bulkheads at the airport. My first flight is out of YVR - would a LH agent there be able to assign a bulkhead to me once the checkin window is active or do I have to see an agent in FRA?

Thanks!
