Cyrano, firstly, you're quite right, I was mistaken as to how long the INV route was operated, I should have checked my facts. Also WHBM I don't know why the ground staff told you the flight was full, that will be forever unexplained, maybe they were expecting and Embraer!? I'm sure you understand though that stipulated weight and balance tables for particular aircraft layouts (with their constraints) will dictate where the passenger load have to be located on any particular flight. I understand that it might seem all passengers have been crammed into a small area of the cabin without good reason (incidentally I have checked and this service operated with 66 pax on board), other factors such as hold loads etc. would affect the weight and balance for this configuration but they wouldn't have placed all the passengers into the front of the economy for no particular reason. The groundstaff were probably a bit phased by this strangely configured beast arriving in place of the 319!
