Now all these aircraft on order may never come to fruition but it certainly is possible growth is on the horizon, especially as the smaller regionals start to fold.
They'll never see that many aircraft. The amount of 70 seaters will soon be maxed out at delta and united and the only way for that to change would be a change of scope. There's no way that is happening in the next decade without some sort of financial meltdown.
