Glad they got a sale...wonder how many units they sold. Can't be that many as North American Airlines only has 11 airplanes:
"Since 1990, North American Airlines has been a world-class international carrier with a superb history of safe, reliable and financially successful operations. With a reputation for first-class technical and operational performance, we operate a fleet of 5 B757-200 and 6 B767-300ER aircraft serving millions of passengers at destinations around the world."

5000 units sold from the 30 airlines they mention in press release is only 166 units per airline.
