I dont have to. I have proven that our wages are lower than many of our competitors and I've proven that we do more work in house and that the company chooses to do more work in house than they are contractually obligated to.
I suppose thats why they need to keep it secret for competitive reasons.
We keep hearing this figure of $600 million but nobody is saying how they came up with that figure. Are our labor costs $600 million higher than Delta/NWA? Their costs will probably be around $6.8 billion. Not Higher than United/CAL which will be around $6.7Billion while AMR is $6.2. Thats the big three. So in reality AA/TWA pays around $500 million less than UAL/CAL and $600million less than DAL/NWA and they do the most work in house of the big three.
Your posts appear to mistakenly assume that Brundage's $600 million cost disadvantage brick consists solely of maintenance costs. Brundage was talking about all AA's aggregate labor costs, which include some not-so-productive pilots and FAs, both of which fly less than pilots and FAs at the other legacy airlines. AA's pilots enjoy pay rates substantially higher than at UA/CO and AA's FAs, despite their assertions, are some of the most expensive in the industry (save, perhaps, for WN).
Delta/NWA have many more planes, pilots, FAs and fly many more ASMs than AA, yet its labor costs are only slightly higher. Same thing at UA/CO which is substantially larger than AA.
Yes, AA performs more maintenance in-house than the others. How much of AA's labor line item is attributable to TUL and AFW? Brundage didn't say that AA faces a $600 million brick due to its maintenance expenses - you're the one tearing down that strawman. AA's maintenance expenses may very well be inline with the others because AA's line mechanics make so much less than at WN and some other airlines.
Subtract an estimate for AA's overhaul operations' expenses from AA's wages, salaries and benefits total and then divide what's left by AA's ASMs. The result is still more labor cost per ASM than at the other airlines.
AMR's total labor expenses this year will total about $6.9 billion (not $6.2 billion), but that includes Eagle employees at their much lower wages. AA's mainline wages will total about $6.3 billion. Of course, UA/CO doesn't own any regionals so regional pay will be reflected in their contracted services. DL/NW owns a lot less regional capacity than in the past, so some of their regional wages show up in wages and some shows up in contracted services.
