Is it unusul? No, not for a company staring bankruptcy in the face.
The question was is it unusual for a 75 year old company that has long term leases for most of its facilities?
Yes, cash flow is critical, but AA's cash flow is not sufficient to service the debt and pay all the bills. That's why the company has continuously borrowed since 2003 and has sold additional stock since 2003 and has sold off non-core assets since 2003 - all in an attempt to raise cash.
Yes and they spent much of that money on new terminals, new computers, appliances, mods on aircraft and all sorts of other non-essential expenditures. They would add winglets to save fuel, big expense, down time on the aircraft, labor and the parts but not repair ground power units, a small expense, very little labor, no aircraft down time. So they would have these fancy winglets on a plane with the APU running all night. It would be like me paying for Solar Panels to save electrcity costs and then turning everything on and leaving it on. Like I've said, they've been burning the cash. From 2003 till somewhat recently AA was paying down their debts after 2003, not long ago it was much, much less than what they are quoting now, all of a sudden its $29billion? Wasnt it around $10 billion two years ago? IIRC we discussed how AA claimed they owed over $20 billion back in 2003 and you said they never owed that much, so do you really believe they owe $29 billion now? If so how much of that is tied to aircraft orders? Is this BK just a ploy so AA can buy new toys?
You have the same deficiencies as Mr Shotwell when it comes to balance sheets. If you bought a house for $150k and borrowed $100k, then your net worth is $50k (asset of $150k less the debt of $100k = $50k net worth). The total of your payments is $260 but that does not define your debt. The liability side of AMR's balance sheet does not include the total payments due on its debt - only the payoff balances, like the $100k debt on your house.
Perhaps a more clear example would be a lease, when the company enters into a long term lease the payments over the term of that lease are added to their liabilities. Sign a ten year lease for $10 million and you just added $100 million to what you owe. Even with the house example AA is in better shape than most of us were when we bought our homes, in my case my debt was double my gross revenues, AA's liabilities are only around 20% more than their annual revenues. If I had torn down my home, as AA did in JFK and MIA and built a new one my debts of course would be much higher, and my home is much older than either of those terminals were.
