I am not sure Ill say this correctly, but if I read the scope on 90 seaters they can not be over a maximum certificated weight of 86000 lbs. All of the 90 seaters I saw all weigh significantly more than 86k. I don't believe the 90 seaters can be used. I was told that was one of the sticking points during the contractual writing. The company claimed it was a 96 k lbs. weight limit, the union claimed 86 k and the mediator agreed with the union. R/..... Sluggo
