ages 11,13,13,15. Is a direct 10 hour 14 minute flight (direct Dulles to Honolulu) too much for kids to endure? I've never been on a flight that long... longest has been to Europe. Alternative is to split the flight into two legs via LA or SF. I guess it comes down to the specific kids but can imagine the 11 year old wanting out of the plane 1/3 way there. Maybe if they're loaded for bear with iPhone/iPads/movies/shows they'll be fine.
