As the airlines continue to try and squeeze out every penny of profit, one of the ways they do it is by putting as many seats in an aircraft as possible. As a result, we’ve seen seat pitch --  the space between a point on one seat and the same point on the seat in front of it, according to Wikipedia -- and seat width steadily decline.

The average seat pitch in coach class on U.S. carriers is between 30 and 33 inches, and seat width is 17 inches to 18 inches, which isn’t very comfortable, even for shorter people. With all the controversy over passengers being blocked from reclining their seats thanks to the Knee Defender, below is a list outliting seat pitch and width in economy class for the top five U.S. airlines.
