It seems pretty cut and dry to me: $1.8 billion in sales, 400 airplanes, 1400 pilots....sounds like a major to me!
Let's see: UPS, FedEx, Alaska, Continental, oldTWA, America West, Airborne Express.....they are majors - but EJA is bigger.
Don't forget that up until a few years ago, commuters were 135 - they are only 121 cause the feds requires them to be. They were considered airlines - albeit Scheduled Part 135. So, EJA is a 'Unscheduled Part 135" with licensed dispatchers and an airline type schedule/work rules and conditions.
If it quacks like a duck....
