I’m wondering specifically which airlines have the most legroom in economy or coach class. I recently took a flight on United. They have made the first 10 or so rows in Economy into an “Economy Plus” section, with extra legroom (charging extra for those tickets). But it seems like the back half of the plane was squished in order to accomodate the extra room for Economy plus – and the plain old “Economy” seats had very little room. I’m wondering if people have seen signficant differences between different airlines. Which are the best in terms of legroom and more spacious seats? Which are the worst?
