This isn't a fair statement to make with regards to the E175. That aircraft, regardless of where you sit, is more comfortable than any mainline bird. You won't have a middle seat and if you sit up front, you have your choice of sitting by yourself. 1A and 4A are the best seats in the industry on the domestic side. And considering LAX-SEA isn't a hub to hub AA route, I'm just glad they aren't flying the CR9 or E145 between those cities. With AA, between LAX-BOI and LAX-SEA are comparable in terms of aircraft utilization. In fact, this is a newish route within the AA route structure. And this is coming from someone who is 6'5", FWIW
