Without knowing your tastes, it's hard to come up with good recommendations, but these are some suggestions.
On the fantasy side there's Patricia McKillip, and a couple of Sharon Shinn's books that you might like (_The Shapeshifter's Wife_ and _Summers at Castle Auburn_). Another YA series, Jan Siegel's _Prospero's Children_ and its sequels could be worth a look, though I don't know how easy they will be for you to find.
Given that the latest followups have recently appeared, if you fancy a Dumas-pastiche fantasy Steven Brust's _The Phoenix Guards_ is likely to be in print - and it should last you a good long time on the flight.
From what I've heard about Kitchen Confidential I don't think that I would take it on a long flight. Unless it's to kill your appetite enough to refuse airline meals :-)
