Substantially all of US Airways' employees meeting certain service and other requirements are eligible to participate in various pension, medical,
dental, life insurance, disability and survivorship plans.

The following table sets forth changes in the fair value of plan assets, benefit obligations and the funded status of the plans and the amounts recognized
in US Airways' consolidated balance sheets as of December 31, 2011 and 2010 (in millions).
Year Ended Year Ended
December 31, December 31,
2011 2010
Fair value of plan assets at beginning of period $ $
Actual return on plan assets
Employer contributions 8 14
Plan participants' contributions 16 16

The following table presents the weighted average assumptions used to determine benefit obligations:
Year Ended Year Ended
December 31, December 31,
2011 2010
Discount rate 4.13% 4.93%
US Airways assumed discount rates for measuring its other postretirement benefit obligations, based on a hypothetical portfolio of high quality
corporate bonds denominated in U.S. currency (Aa rated, non-callable or callable with make-whole provisions), for which the timing and cash outflows
approximate the estimated benefit payments of the other postretirement benefit plans.
As of December 31, 2011, the assumed health care cost trend rates are 8.5% in 2012 and 8% in 2013, decreasing to 5% in 2019 and thereafter. As of
December 31, 2010, the assumed health care cost trend rates were 9% in 2011 and 8.5% in 2012, decreasing to 5% in 2019 and thereafter. The assumed health
care cost trend rates could have a significant effect on amounts reported for retiree health care plans. A one-percentage point change in the health care cost
trend rates would have the following effects on other postretirement benefits as of December 31, 2011 (in millions):
1% Increase 1% Decrease
Effect on total service and interest costs $ 1 $ (1)
Effect on postretirement benefit obligation 16 (12)
Weighted average assumptions used to determine net periodic benefit cost were as follows:
Year Ended Year Ended Year Ended
December 31, December 31, December 31,
2011 2010 2009
Discount rate 4.93% 5.51% 5.98%
