This does seem like an interesting thread, and could be a good question to ask of many airlines. I'm unsure why you "just don't like the A-320", wish you could explain a little more as to why that is, but nevertheless, it is interesting as to why airlines choose the aircraft they choose.
You also "wonder if Jetblue would do better with the 757 just as Song is?" That is a good question, but at the same time, is the B757 really the aircraft that JB
needs? The B757 might seat more people, but would JetBlue be able to fill those extra seats? In addition, is the B757 right aircraft for the fleet at all? National tried to use a common fleet of B757s out of LAS
, and it has since failed.
At the same time, perhaps the B737 would have been a better fleet for JB
, but as Greg pointed out, "Airbus beat Boeing in both price and delivery positions", which is something an airline needs to consider when buying planes. I'm just guessing on this next item, but perhaps JB
wanted to use a different aircraft than SWA.
As for the Embraer order, time will tell how that works out. I do think it is an interesting strategy to get your "own" regional jets instead of contracting with another airline to supply that service. At the same time, this order also goes against what JetBlue has marketed itself as, a single-type operator. It will be interesting to watch and see.
BoingGoingGone also makes a very good point, "Why don't we wait and see if JetBlue even survives 10 years." I understand that Jetblue has been doing very good financially, which has given them a good base to buy more planes and expand, but in some ways I'd be worried about this expansion. As history has shown, over-expansion too fast can spread an airline too thin. While JB
was able to stay under the radar for a while, it is now having to compete more and more with the majors. Song is the combat force of Delta, perhaps once the airline industry straightens out, the competition will become more fierce.
There are many questions, many options, and going back to the first question of this thread, will the A320 be the right choice for the airline? Only time will tell.
