Major carrier with "300 airplanes and a very limited network"? Not so...... I guess filing BK twice has it's advantages .I remember it differently. US made the leap from "major carrier" to low cost carrier. That's what saved US. That's why US isn't on the brink of bankruptcy and is doing fine as a stand alone. On a side note US is a "major carrier" even though it is a LCC. Admittedly a dysfunctional major carrier just the same.
