In my experience, while it may be tougher than it was, I always find AAdvantage to be the most redeemable -- even though I'm not a big AA flyer. This becomes more and more important as the others - ESPECIALLY DL! - get much tougher. This comment re DL is actually more in regard to the subtle increase in mileage requirements, with "25,000" evaporating at a painful rate.

And welcome, AJBT.
