I am getting ready to book a multi-city trip (domestic) on Qantas and one of the flights I would like to book is on a DHC 8/400. I assume this version is covered by the carry on requirements for the Dash 8? The website says one carryon. Anyone know if that is one carryon plus a personal item, or only one item? Really need to know if my wife can take on a small backpack and her purse?
