I don't know..... Mullin at one point before Song's initial launch had said that 737's would probably play a role in the then future LCC. But by adding an additional aircraft type, the costs of the LCC will go up. Delta has around a 100 757's, so it could move more over to Song and use 737-800's to fill in the gap at mainline. Of course, if Delta does order a large number of 100 seater planes, Delta may go for more frequency on certain routes with smaler planes, thus freeing up the 757's for Song. Delta has never said that it would hold Song at 36 planes, just that by this year's end 36 planes would be flying. A lot depends on how successful the brand is, and what markets Delta thinks it can enter. A lot also depends on what the future of the US industry is. If one of the large carriers were to go under, Delta might expand Song more. Imagine if UA
were to go under, and there is no certainty that it will, Delta could easily move in to the LAX
route with a bunch of Song flights. Ditto with LAX
, and LAX
. If they got certified to fly overseas with 757's, they could even serve HNL
frequently each day from LAX
. That would be a logical market for Song, and it would give them a leg-up on SWA and JetBlue. But that is a lot of if's.
