Always make sure that there are plenty of sick bags in the back of each seat pocket, make sure that rubbish like lolly wrappers are removed from under the seats and seat pockets from the previous flight, make sure the windows are spotless, especially if doing a scenic flight and have the seatbelts nicely presented.
Most importantly don't become complacent, even if you've done the same flight 100 times before, there's always more to learn, and have fun along the way!
