They have expanded at a steady rate but have a very good product both in the airline and the holiday company. I know they have bought a lot of B738 but the B733 are long in the tooth now and are coming to the end of their life, I can only speak for Manchester but there is only 1 B733 left and that is due to finish here shortly however they have certainly earned their bread over the years and I am sure PM did s good deal with Boeing as the B738 comes to the end of it`s production life and the MAX only just getting going.
