I've been staying at Starwood for a while now (Platinum), but I'm also diamond at Hilton. I had a recent 4 night stay at Hilton and I checked my HHonors account - I got a ton of HHonors points (I know 1HH does not equal 1SPG point), but I also got over 1,000 points on Aeroplan. I could have had points on virtually any airline (Delta, American, United, .... a rather lengthy list). Got me to thinking that I've missed a lot of airline points because 1) I've switched my loyalty to Starwood, and 2) I don't fly Delta (doesn't work for me). Am I missing something?
