In December, the APFA posted a document alleging that its plan was 99% funded as of Jan 1, 2010.

Given that the overall funded percentage of all four AA plans was only about 66.5% on 12/31/09, I'm skeptical that the FA plan was 99% funded, but that's what the APFA said.
One thing is for sure, over 1,000 pilots have retired early since 2008, and unless they were brain dead, each one probably exercised the lump sum option for their A plan balance. In 2011, nearly 500 retired, and it's not unreasonable to assume that perhaps $750 million or more was withdrawn from the pilot plan - leaving it severely underfunded. Last week's 10-K confirms that the overall funded percentage was worse on 12/31/11 than it was on 12/31/10.
As of 12/31/11, the overall funded percentage of all four plans was just 63%, down from 67.5% at 12/31/10 even though markets recovered in 2011. In 2011, the investment gains equaled 7.9% of the value on Jan 1, 2010.
All of my percentages are computed with the Accumulated Benefit Obligation (which AA uses when it publicly states the funded percentage).
