I don't care, as long as they're FASTER!!!!!
As a matter of interest, attached is the (N.B. scheduled) travel time over the last decade and a half between the two cities I (used) to fly most frequently with AC....
DC-9 1:20 - and was often faster than 1:15.
A320 1:30
CRJ 1:42
DH4 1:52
Travel time is now 40% longer. Space is horrific (CRJ was the worst) and noise levels close to unbearable (DH4).
If they go to a A320neo, I might just switch from WestJet. As in, Might.
