We have
legacy/major
National / LCC
Regional
ACMI (can’t say cargo, since there are passenger only ACMI)

A Frontier, Spirit, Allegiant, Sun Country and the rest of the National LCC’s are not legacy or major airlines.

An example. People still run to leave a Frontier, Allegiant or Spirit when a Delta, United or American calls....
they just aren’t the same category carrier.
