My biggest complaint with the book is that it's a bit short on recent details. Coverage of Island Air, for example, is pretty much limited to the start as Princeville Airways, the acquisition by Aloha and name change to Aloha IslandAir, the crash on Molokai, and the final name change to Island Air, and the sale to Gavarnie Holding, though the acquiring company isn't mentioned by name in the book. Omitted from Island Air's history is the airline's brief flirtation with the Dornier Do 228 and eventual replacement of the Twin Otters with the Dash 8. It also missed the point that a contributing factor to Mahalo Air's downfall was the replacement of new ATR-42s with older examples that ended up costing the airline a lot in maintenance expenses. I can forgive omission of some of the recent events due to the lead time in book publishing, such as Island Air's planned acquisition of Q400 aircraft and details on Mesa and FlyHawaii's plans (though FlyHawaii is also not mentioned by name). But completely omitting Pacific Wings is a definite oversight.
However, one must keep in mind that it's easer to find out about more recent events, and perhaps omitting them now is reasonable course of action in favor of waiting to see how they effect the industry in the long term.
