We have backpacks that might work for a personal bag IF we don't pack them full, but IF we wanted to abide by the strict 40x30x15 cm (16x12x6"), do you have a backpack you would recommend? We may need a few for our family of 4 so budget friendly is good. Prefer backpack style. I have researched and have a few options, but would like to know what you have found. (Does not need to fit a laptop.)
*Sounds like Air France is our most strict airline during our travels. This is on the way home should we need to check instead of carry on.
