Yes, three of our 757-200s (as mentioned 'AN, 'LJ and 'LK) have the 35" seat pitch, they almost exclusively operate our Canadian Affair flights but do sometimes operate shorthaul services between flying to Canada. It's an enormous amount of seat pitch and consistently get excellent reviews. The remainder of our fleet (all of the Charlies, 'BA and the other Limas) have a standard charter seat pitch like on our Airbus A320/1 aircraft of between 28 and 30 inches on all seats besides Row 1DEF and 2ABC as well as the emergency exit row seats.
You won't be able to go into the flight deck in flight obviously for security reasons this is prohibited, however you could always ask the crew in flight if the flight crew don't mind or have the time for visitors on the ground. Remember in IBZ there are slot restrictions and turnaround times of 50 to 60 minutes so it might not always be possible, but the flight crew almost always like to say "hello" if they can.
