Industry standard is 31. Let me know what carrier's have planes with that kind of pitch. All I can find on SeatGuru is NW's DC9s. To me that inch is a big deal, but then again I'm tall. If biz class were available for an extra $35 at time of purchase over the cheapest fare, that would be fine, but it's not. It is actually $40/60/80 more depending on flight distance more than the full Y. Sorry, I find other carriers products offer much more value for the money at time of booking. If I could be guaranteed the upgrade for $40/60/80 off of any fare, that would be worth my money, but I can't, and won't risk being stuck in 30 inch pitch.
