The medium carrier should fit under the seat, as long as there are no life jackets located under the seat (it was a problem for me but it was on an Air Canada flight). The top will smush a little, it'll take some wrangling, but it can be done. Try to push it as far back as you can since you will have little room for your feet. Good luck!
