Lots of new destinations in the future. (Some which may surprise you)
The number of 170s to be acquired is planned and therefore can’t be made public until Dougweiser’s money men give the green light.
As far as increasing fleet numbers, I wouldn’t count on it.
My opinion is they’ll do a one for one swap with the existing fleet of 140/145s
Recruiting is so far behind that it’ll be a miracle to keep cheeks in the seats of what we have numbers wise now.
Expect attrition to increase which will only exacerbate the staffing situation.
