Yeah, but he gets royally screwed on the conversion. He's dating a French girl so he's gotta be broke (or soon will be).
Ah, that makes sense on short notice with very specific flight requirements. I think that also eliminates Aeroplan from the process because Saver inventory is required for partner awards.
I wouldn't do this, but:
11,000 Membership Rewards points could be transferred to 3,663 Starpoints. This would bring the SPG balance up to 21,663, which could transfer to UA 13,331.
It appears that Points.com will exchange 20,000 Aeroplan for 7,467 Mileage Plus
60,000 + 25,000 + 13,331 + 7,467 = 105,798. It would cost $188.13 to buy the remaining 5,000 UA miles.
