Low cost airline
I am not sure JetBlue is
:
As you know
the A320 are equipped expensively
, the landing fees at JFK
and other major airports are very high (5, 10 , 15K...).
Low cost airplane for SW
, low or n
landing fees, labor under control
, in a position to seriously take on the big guys in every part of the country
.
The models between SWA and JB are very different. But here lies the opportunity of upgrading rapidly and having a good seniority.
I would go with SWA
