Not sure why you felt the need to reply

You said fuck you to those who refuse to stow under the front seat. I'm telling you why. It's the only way I can stretch my legs out a bit, having my feet under the seat in front of me. My backpack goes in the overhead bin and obviously doesn't take nearly as much room as a full-size carry-on. Might get 2 or 3 backpacks in the same space. Some people think because my backpack could go under the seat in front of me I should be obligated to put it there. Some demand a stewardess help them find the backpack owners and get them moved so they can put their suitcase overhead. No, screw that... check your suitcase. I checked mine, you can check yours. I'm not making myself more cramped because you wanted to save $40.
