Thanks everyone for all the good advice
Let me add some additional comments:
This would be what I am hoping for. I'm booked in Y-class and I have just over 40,000 EB Points that will expire this summer, so if the planets align I'll be in C both ways and burn my points before expiration!
In this specific instance, while a complimentary op-up would be nice, it actually wouldn't make any difference to me as this is probably the only chance I will have to use the miles before they expire...
Also, I'm currently status-less in *A, so the complimentary up-op scenario is not very likely. (will be UA 2P/*Silver after the outbound part of this trip)
Aah, the never-ending quandry of where to book your miles... (getting a little OT here)
I was EBG for a number of years but after I relocated to IAH I chose to jump ship to CO as they are hard to beat to just about any destination out of IAH.
I might have another relocation coming up, this time to a part of the world that CO
nor Skyteam doesn't even serve...

So I'm jumping ship to *A.
My biggest peeve with EB is the fact that your miles expire, which aggrevates me to no end. That, plus the fact that I can get *G status with 50,000 UA miles versus 70,000 EB points. Also, the majority of my travel is in cheapest-fare-economy, so the *G lounge access will be a definite perk.
