Alaska Airlines just released its 2011 figures and I thought you'd be interested in a few points based on its filing:
1. Its total operating revenues were $4.3 billion, which is an increase of 12.7% over 2010. Kudos Alaska!
2. People frequently say labor and fuel are the biggest buckets of an airline's cost, and in Alaska's case, aircraft fuel cost $1.3 billion, or about 30% of its revenue.
3. Next is wages and benefits at $990.5 million.
4. So, how does this compare to maintenance costs? Well, Alaska spent $205.6 million last year on aircraft maintenance, or just 5% of revenue if I'm doing my math correctly.
5. Here's one just for fun: landing fees and other rental costs: $238.2 million.
