Hi everyone
Have checked a ticket for an up coming flight.

In the endorsements/restrictions section it says the following:

Endorsments/Restrictions *M*NON END / NON REF / VALID FLTS DATES SHOWN ONLY / UPLIFT VALUE RESTIRCTED

Anyone know what the last bit means? Does it mean I'm less likely to be offered an upgrade (if available of course!) through MMB or at the airport as a POUG. I'm travelling WTP. What does the M Non End bit mean??

Does it mean something different altogether?! Just curious!....

Thanks
