A friend and myself booked flights to NRT with the intentions of useing his SWU on our flight. I'm a 2p and he was a 1p at the time now a 1k.

As we go to use the upgrades it comes back that we booked a 'K' class ticket. We were unaware at the time this was not an upgradeable ticket or even that we booked a discounted flight considering that we booked on United.com and did not use a promo code or any other type of discount tools.

Does anyone know of a way I can have united change the booking code to an upgradeable ticket or anyway we can still apply the SWU?

Much appreciated
Thanks
