Just changing tack slightly .I'm probably getting a D class RTW fare and will cross the USA from SFO to JFK. I would like to upgrade to NF(Premium Class) using 1k confirmable 500 mile certs However, I see on the back that they cannot be used to upgrade to NF from D.
As I can't access UAMP eug site (its down)I don't know if this also applies to to eugs.
It doesn't on the standard 500 milers.Does anyone know?
Since F seats are few on these 767 services,
I'd like to grab one as soon as one comes up.
Thanks
