We flew on United and found out after purchasing the ticket (on Priceline) that you don't get to pick your seat if you buy an economy class ticket, which is the only class you can purchase unless you want to spend a ridiculous amount for your ticket. United has in writing on its website that they don't try to seat you next to family/travel companion if you have an economy ticket, and you can't reserve your seat until you're at the gate! We were on a brand new looking Boeing 737-800 for 5 hours and that thing squeezes you in with now leg or shoulder room (I'm only 5'5"!), and even the restroom is tight for me! I noticed that farther up in the plane the seats have distinctly more leg room and are wider. United is charging the same for what they now call "economy" - what a crock! Never again will I fly "the friendly skies"!
