I got a UA RT flight booked in Economy via LH.
My UA MP number including seat reservations are saved via LH website.
But when I open the booking on UA website, it shows no frequent flyer details at all.
When I try to add that information via UA website, it's telling me that there is a mismatch with my name and UA MP details - I think because LH put "MRDR" in there which UA can't process.
I'm a bit afraid to miss out on my opportunity to get upgraded to Eco+ due to UA MP status.
What is the easiest way to fix this? Will it work at check-in? Call UA? Call LH to remove the MRDR from my name?
Thanks
