Knotcher;
I disagree with the guppies being "new". The airplane might be straight off the assembly line, but it is at the end of its' product cycle. We are buying "old" generation airplanes, that will have to compete with 320NEO's and GuppyMAX's for the next 25 years.

I think the timing on buying more NG's is way, way off. Should have bought NEO's. 321's with big motors are a gigantic step up from 900ER's, and the 321 NEO is going to do an almost good enough imitation of a 757 for most airlines needs. 900ER's are an abortion by comparison.

As far as passenger experience there is very little difference. Yeah the old TV's hanging in the isle aren't that great. But neither are the little 12 inch LCD's, 3-4 rows up from you.

Both suck compared to an Airbus or 190 with 1 inch wider seats, and LiveTV for free like Jetblows.
