I don't disagree that regionals aren't losing money. I was at one that made money hand-over-fist when majors were hoping for ATSB loans and filing bankruptcies.
If you think more money (percentage wise) will go into one budget without coming out of another, you might need to go sit in on some budget meetings or something.
I'm no finance major, but you can only have 100% of 100%.
And since you brought it up, the regionals have no direct control over raising their compensation levels with their major airline partners with a capacity purchase agreement (or whatever the preferred term is). Some might have had a little wiggle room, but interestingly enough there was an article in ATW about Skywest and how Delta is pinching down on the regionals (you might find that an interesting read).
The conclusion it brings us to is that the current regional compensation structure leads to what I've termed for years as "management by spreadsheet" where the number of ASMs are bought by the mainline, whether it be the contractual minimum or the max, and all the management has to do is input their costs. If the costs are lesser than the compensation, great they are heros. If not, they lose money. It's not like they can call the marketing department and say "Hey, Paul, raise all the tickets $1.00 to help us cover this budgetary gap!" If the expenses are greater than the compensation from the big daddy, they're done.
Like wise there can be a problem if the managment's current plan is based on a higher-than-minimum contractual compensation rate.
What's always cut first? CEO Pay, interior maintenance of the aircraft or cutting in house maintenance and outsourcing heavy checks?
