Great Bag - Recommended buy
Used this bag last year for a 10 day trip in Hungary, it went through the airport no problem, complying perfectly with the carry on sizes (requires upgrade to XL).
The stow away straps were really convenient and comfortable to wear meaning it fits into the overhead compartments very easily.
At 1.3kg, it doesn't use up too much of your weight allowance and has enough space to carry a weeks worth of clothes including a change of shoes. There's a built in laptop sleeve and other small pockets that make storing, organising and accessing items (passport, money, phone charger etc....) really easy.
