tallseabird - further to aeulad's comment (above), all AEU B737-700s are configured with 148 seats.
However, the passengers load on the LGW/DeerLake route is capped at something quite a bit less than maximum number of seats ( wherein a figure of just over a 100 people comes to mind ).
ElectroVlasic - AEU B757-200's have at least a 35 inch seat pitch throughout the whole cabin ( and all with business class type seats ). As I presently understand it, AEU's B757's should take over the Deer Lake route toward the end of March ( when it goes to twice a week - with crew layovers !
).
