Does anyone know how much the seat pitch varies on Continental''s 737s? I recently flew DTW-IAH and had a 737-300 outbound and a 737-800 on the return. CO''s website claims both have a 31 pitch, but I can say with absolute certainty that there was more effective legroom in the -300 than the -800. The -300 was uncomfortable - the -800 was some form of medieval torture device. Do the two have a different pitch or are the seats that different? If its the seats, I certainly hope they go back to the seats that were on the -300. I may relocate to Houston soon, and if that''s the legroom that''s standard, I''ll be connecting through DFW instead.
