Flew Siem Reap to Phnom Penh on the ATR72. Be warned as a backpacker (or anyone who travels with carry on luggage only) that the overhead compartments fit nothing much bigger than a handbag. So you'll be nursing your bag under your feet or on your lap for the flight. The way the seats are constructed (2+2 layout) also means you can't stow your bag under the seat in front in the window seats. Not sure how well maintained the plane is either crossed my fingers and hoped for the best really. Luckily this flight is a very short one and landed quite early. Captain and cabin crew very friendly and free drinks served on a very short 30 min flight a welcome touch in the hot humid weather. The flight did have something i haven't experienced on a plane since the 1980s - the distinct smell of cigarette smoke!
