Alright here is some extremely simple math with numbers to explain how easy it COULD be...

American Airlines alone flew roughly 100 million passengers in 2013. If you raised those 100 million tickets sold that year by $10, you have just generated 1 Billion dollars more in revenue for that year. Divide that out by a work force of 40,000 crews (include flight attendants, airline pilots, mechanics, etc.) That is a $25,000 a year raise for 40,000 crew members.

That 100 million passengers is how many passengers were carried on American metal. This doesn't include the 10s of millions carried on their regional feed.

I think it is easy to ascertain that raising pilot wages would not be difficult, and it would not really hurt the mainline companies at all. However, until pilots keep thinking short term and vote in concessionary and limiting contracts selling themselves short, a raise that everyone wants will never happen.
