Again, and I’ll type slooooow. Look up the definition of a ”Major Airline”. The DOT's Bureau of Transportation Statistics as well as 14 CFR 241, Section 4, "Air Carrier Groupings" both identify Majors as carriers having annual operating revenues exceeding $1,000,000,000. It’s a game of semantics clearly, but since you started it, I figured the facts should be used. Clearly this all started because you initially took offense to Spirit, Frontier, or whoever not being called “Mainline.” I’m done arguing with you, enjoy your time at Frontier or whatever LCC you work for.
