I have been slightly better with standard seating over high density on routes that I have competition. Not sure if that has anything to do with the seating or not. I think I have slightly better frequency on those routes as well though. It always seems like load factors stay about the same regardless of seat type on the aircraft, but maybe that is just me. If you have 40 seats and are selling 33 on a regular basis, dropping down to 32 roomier seats on the airplane has actually resulted in fewer seats sold for me in the past. I am assuming it has something to do with the way company and route image affect load factors? Of course that was back during ver. 1.2. Not sure if that has changed since. Feel free to correct me if my experiences are different from others. I have not spent nearly as much time in game here as most.
