Posted By Ken Urquhart Mark, Look at the Airlines web sites. They generally give a description of there various Cabin classes which usually gives some seat spacing and pitch detail. Since September 11th., however, many specific details of cabin layouts and plans of aircraft have been removed from the airline web sites, for obvious reasons. You might therefor be best advised to contact each airline direct and discuss with them. The other issue to consider is that different airlines with the same aircraft have different cabin layouts and configurations. Hope this helps. Regards Ken Urquhart
