The odd thing about Delta is that when it had an "alliance" (or whatever it was) with CO - you could often get Delta reward flights on the CO website cheaper than you could get them on the Delta website. That is still true of the CO website - and some of the flights it offers on other carriers (like Air Canada if I recall correctly). You have to be a little careful though - because some flights that would be front of plane BF on CO in 2 class planes are middle of plane business-class on flights that have 3 classes of service. That isn't always true though. We once got a CO reward ticket on Virgin Atlantic "Upper Class" (MCO to London). I think that may be the only time I've ever been in the front of a plane that had 3 classes of service.

I don't purport to understand the logic behind any of this - because there doesn't seem to be any! Robyn
