I was thumbing threw a book on US commercial airlines that Alaska outfits all of its MD-80s with 135 seats. This book was published in 1996. It is my understanding, backed up by the OAG, that all AS MD-80s now have 140 seats, suggesting that they squeezed in an extra row of coach (5 seats). But, sometimes books can give inaccurate info, especially when the book covers many airlines. The reason I was curious is that I have not noticed a change in seat pitch, and adding a row of coach should decrease the legroom by around an inch I would imagine. Can anyone verify this. Also, I was curious as to whether AS will adjust the legroom on their 737-400s when they add another row of First Class. It seems to me that legroom used to be one of their biggest advantages, but that it is now only slightly better than average.
