When CAL LITE ran out of GSO there were similar comparisions. while the numbers are dated, the gist of the matter is the same
2 737s sitting across from each other, (callite/usair), before you put fuel in it, oil in it, crew it, sell the tickets for it, pay for the gate space for it, perform maintence on it..... there was a 30,000 dollar per month difference in the two planes
this came from someone higher up signing a contract to buy/lease the airplanes 30,000.00 PER MONTH more than the other airline. so before you even pushed back you were running at higher costs than the other guy BECAUSE someone else put that deal together. not benefits, not hourly pay, not seniority, ect..... just like the 600 million in "non performaning investments" of the early 90s. fuel hedges that went against the airline because they were derivatives using the YEN. again another huge mistake.
so for the purposes of this thread, how much does airline A pay for the 737 and how much does UAIR pay for the 737.
that is something none of the "worker bees" have control over nor can any amount of givebacks cover continual descisions similar to that.
simple enough to check under aircraft rent in sec documents
