A couple years ago I was also flying brand new 320's with an 11k pound higher gross weight than UAL's 25 year old models, and they had 2500 lbs/thrust more power per engine than UAL's. CFM's by the way.
Ours are early models. Newer 320's and 321's are more capable than older ones.
The first A320 came to UAL in December 1993, the last one in October 2002. Not saying they are spring chickens, but the average is still a ways from 25. And none of them have those cow utter looking things dropping out of the overhead panel.
Also. the V2500 is made by IAE, not CFM. Thrust is 26.5K for the 320 and 22K for the 319.
