飛機座位問題（１０）

The seat pitch vary between airlines...
And for most airlines, First Class will have a seat pitch of around 80" and approximately 35~40" of seat width... While for Business Class, there is a seat pitch of around 50~60" and seat width 32~35"... Finally for Economy Class, there is a seat pitch of around 30~33" and seat width of around 20~22"...
But for some airlines, they have a upgraded Business Class product with a seat pitch of around 80" but with the same seat width of approximately 32~35" and also have a Premium Economy Class product which will usually have a seat pitch of 45~50" and seat width of around 25~30"...
But as I have said, the seat pitch and seat width vary between airlines and their product are different... So it is hard to tell you the actual seat pitch and seat width... And usually there is a range of different seat pitch and seat width depence on airlines...
