Lots of people fly them... doesnt mean the like them.....
I personally think its a good move... but rick makes some good points....
I can tell ya Delta is the one pushing our E175's to replace the E170's we already fly for them..... what do they gain? SIX more first class seats.... same with the 900's they have in service... and its my understanding they may be converting some of the 700's to a 2 class service.....
I suspect the Q400 can be bought in a 2 class config..... that might could be a huge selling point for some companies........
Cetainly some pax just plain dont care... but I believe more care than any of us would like to admit..... Im am positive Horizon will do fine with them.
