And, since we are speaking of Delta's seemingly enormous hourly wage increase, much of the additional compensation for a U.S. airline pilot was in defined benefit retirement and legacy work rules like getting paid for trips dropped by vacation or schedule conflicts. Some of this stuff was whittled away by negotiations to 'save jobs' and the rest was cut by 9-11 force majeure and bankruptcy.
As a result, even if the hourly wages look large, the compensation is still reduced from the glory days of the Y2K era.
FedEx and UPS never went bankrupt and still have a surprising amount of legacy 'synthetic pay components' in their contracts. Things like trip rigs, duty rigs and minimum pay per duty period. And, of course, a defined benefit pension program.
