Hello, We leave for Auckland in 57 days! The general documentation says roll-on carry-on may be difficult and may not fit in the hold, resulting in awkward/expensive land transfer. While this is not mentioned in the personalized docs. I called Tauck, they only referred to the published info. My wife is balking at using a duffel as her carry-on (first class problems) The overheads on Embraer 165's are small and the docs say 15lbs. Anyone with interisland charter experience? I've read about some for Hawaii and Antarctica from a cruise perspective. THANKS
