I think its generally held that 19-seaters cannot cover their total costs if they are leased. When wholly-owned the numbers get better but then c/d checks cost are, proportionally, extremely high, as are staff numbers, given how small the a/c are. Even with high LF's, they struggle to earn enough. The recent changes to the effect of price changes has improved matters for smaller aircraft, you can increase revenues and early experience is that 30-seaters have moved nicely into 'profitability' range when that can be done. I wouldn't think that change is enough to benefit 19-seaters though, but would be interested to hear from if anyone who is trying them out in MT7.
