Hi everyone, I am travelling from EWR to SIN via HKG.. as you know this is a long flight. One the way from Singaproe to Newark (the trip there) UAL was delayed for 5 hrs in SIN but they told me ahead of time and offered to put me on ANA, which was great because it was a Y class economy seat and i got 1.5x premier qualifying miles. Even better, i was upgraded to ANA business from Narita to EWR (just awesome compared to UAL). But then no surprise here. OK, the ISSUE : So i saw my name on the top of the upgrade standby list, 44 out of 50 booked people , and 43 of 44 booked around 2:15pm for a 3:15pm flight. I head to the gate and was shocked, the guy, being very unapologetic, told me that because my leg from HKG to SIN (3.5 hour leg) was not upgraded yet, he could not upgrade the LONGER 15.5 hour leg from HKG to SIN. I thought that United allowed systemwide upgrades to be used on one leg? or has the rule changed since the Continental merger. Even worse, the agent said "if you have a complaint, i urge you to write to Jeff Smisek, President and CEO of United".. what a wise-allick response from a guy who could have remedied the situation. Making matters worse, i'm a 1K (which means jack for now) and been flying United for so many years.. so embarassing if ANA (i'm not even in their club) can upgrade me and not united? Is this true? that ALL legs have to be cleared for upgrades?
