Was just watching Airline when a thought occurred to me. What will happen to the financial model of airlines with a single aircraft type when the manufacturer stops producing that type?
For instance: Boeing stops producing 737s and starts making 7X7s(making this up), Southwest has older 737s and needs to replace them.
How will SW and other single type carriers react?
Which aircraft manufacturer will best be able to take advantage of this and why?
Also, please don't make this A vs B, thanks guys.
