Eh???
Stating that "The Emb-145 only needs approx 22 pax to break even depending on what fare levels are set..." is, I am afraid to say, gibberish.
How many pax are needed to make it "break even" (and we could spent ages deciding how that is calculated) depends on how much it costs to run, how many seats are sold, which route it operates, whether the crew will be overnighting etc etc etc etc etc....
You could equally argue that it needs just one pax to break even if the fare level is correct, or indeed that it will NEVER break even depending on the fare levels....
