A quick update on the 4 upgrade certificates and the possible XPs
Premium eco was booked and I used 2 of them.
FRA-AMS-XXX-AMS-FRA
The upgrade worked fine via the TA.
At the end only the XPs of the booked class were credited.
5XPs each for the feeder flight as officially booked in Eco and 24XPs each for the long haul as booked in PE.
But I flew the whole thing in Business.
The vouchers work as an OLCI upgrade at the counter before the flight.
No gifted XPs for Ultis - FYI
