May be this is not the right place for the question but I could not find where else to put it.
IAH-FRA-GDN 11th Oct ( booked in O PZ was available so upgraded to P)
GDN-FRA-IAH 15th Oct. (Booked in O) but flight UA8866 is a codeshare operated by LH and I cant seem to find any way to apply any kind of updates to it! ( PP/Miles/SAUA).... Any suggestions on how to get it ? Also its do not know how full the cabin is so any help there is appreciated!
I am Platinum and will be 1K after this trip if that matters.
Thanks!
K
