Bless those who can afford to go business or first class every time they fly especially on those long-haul flights. If we did that, we couldn't afford to travel as much as we do. In researching some topics for this blog, I ran across some information I found very interesting. Seats are measured by width and pitch. Width is a no-brainer but pitch was new to me. I had no idea. Did it mean the seats are at an angle? Are we not sitting flat in a plane? Here's what I discovered.
Pitch is a measurement from one point on a seat to the same point on a seat either in front of or behind that seat. I guess the point on the seat doesn't make much difference but one picture I saw measured from the back of one arm rest to the back of another. Most of the seats I saw for economy had a pitch of 30-32 inches. This measurement should give you some idea of what kind of leg room you will have (the greater the pitch, the more leg room) but some of that also depends upon how thick the back of the seat is. Some airlines are changing over to thinner backed seats which can lead to a little more leg room but I don't think that's terribly significant.
There is a handy-dandy site that will give you the pitch of the seats on numerous airlines and their fleet of planes. It's called the SeatGuru. You can find seat maps and comparison charts for pitch and width of seats on each plane and even what type of video is available.
Of course if that sweetheart sitting in front of you reclines his seat all the way back all bets are off.
