She is currently booked economy (K), if that means anything to anyone.
BTW, this is the return portion of the trip. The connection in FRA involves a 9-hour layover. This is another LH flight to BUD about 4 1/2 hours earlier.
I guess it never hurts to ask. Where is the proper place to ask? At the departure gate of the earlier connecting flight at FRA? Someplace else?
Last time I asked to fly standby was before deregulation!
