When first commenced, 9C operated the NCL-MAN flights at reasonably odd times and did not really concentrate on the peak periods, i.e. the morning and the evening.
I believe Eastern and the J31/2 would better operate the flights. This airline seems to have it right, and generally, on the more popular routes, operates two morning flights, one lunchtime flight and two evening flights to satisfy the demand for the peak periods. I suspect 9C won't do this; they'll operate one morning flight, one late morning, one afternoon and one evening flight. I don't think NCL-MAN requires this and besides, the AT4 would appear to be a little large.
Anyhow, just my initial thoughts.
