Booked via Austrian with a LH flight number from Munich <> DC in early January (and 2 Austrian intra-europe connections). 2 passengers but I only have 40 PPs.
The online upgrade tool accepts the flight info and passenger names but will not let me upgrade just 1 passenger.
Is it possible to call LH and split the reservation? Some other workaround? Thank you! I've been searching with no success.
