I am traveling from Norway to the US with my dog in-cabin on Friday. I am currently booked on a Boeing 330-300 from AMS to SEA in a window seat in a 2-person aisle, but wondering if it wouldn't be better to be in an aisle.

Could anyone share their experiences of traveling long distances with a dog under their seat in this model of plane? I want to avoid bothering other passengers, as well as avoid getting deep vein thrombosis from not being able to move my legs. Advice gratefully received.
