I can't talk at length about that. All I can tell you is that my experiences in talking with the people who are operating up there is that, with the distances you have to fly and the distance the aircraft is able to fly with a full load of fuel, it sometimes causes layovers, which causes crews to not be able to go to the next stop. Before, they would have an extra two or three hours to fly. They would make it to the next site and complete the run. They may have to lay over a day now and do the remainder of the trip. From what I have heard, it has caused serious issues, there's no question. With crews being as limited as they are, it's true.
To answer your other question, the last 737-200 will be out of service with Air Inuit next summer.
