       As part of our risk management strategy, we periodically
       purchase crude or heating oil option contracts or swap
       agreements to manage our exposure to the effect of changes in
       the price and availability of aircraft fuel. Prices for these
       commodities are normally highly correlated to aircraft fuel,
       making derivatives of them effective at providing short-term
       protection against sharp increases in average fuel prices. We
       also periodically enter into basis swaps for the differential
       between heating oil and jet fuel, as well as jet fuel swaps, to
       further limit the variability in fuel prices at various
       locations. To manage the variability of the cash flows
       associated with our variable rate debt, we have also entered
       into interest rate swaps. We do not hold or issue any derivative
       financial instruments for trading purposes.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       &lt;b&gt;&lt;i&gt;Aircraft fuel derivatives:&lt;/i&gt;&lt;/b&gt;&amp;#160;&amp;#160;We attempt
       to obtain cash flow hedge accounting treatment for each aircraft
       fuel derivative that we enter into. This treatment is provided
       for under the &lt;i&gt;Derivatives and Hedging &lt;/i&gt;topic of the
       Codification, which allows for gains and losses on the effective
       portion of qualifying hedges to be deferred until the underlying
       planned jet fuel consumption occurs, rather than recognizing the
       gains and losses on these instruments into earnings during each
       period that they are outstanding. The effective portion of
       realized aircraft fuel hedging derivative gains and losses is
       recognized in fuel expense in the period the underlying fuel is
       consumed.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       Ineffectiveness results, in certain circumstances, when the
       change in the total fair value of the derivative instrument
       differs from the change in the value of our expected future cash
       outlays for the purchase of aircraft fuel and is recognized in
       interest income and other immediately. Likewise, if a hedge does
       not qualify for hedge accounting, the periodic changes in its
       fair values are recognized in interest income and other in the
       period of the change. When aircraft fuel is consumed and the
       related derivative contract settles, any gain or loss previously
       recorded in other comprehensive income is recognized in aircraft
       fuel expense. All cash flows related to our fuel hedging
       derivatives are classified as operating cash flows.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;

       Our current approach to fuel hedging is to enter into hedges on
       a discretionary basis without a specific target of hedge
       percentage needs in order to mitigate potential liquidity issues
       and cap fuel prices, when possible.

       We also have outstanding contracts for approximately 5% of our
       projected fuel consumption for each of the second through fourth
       quarters of 2011 using 3-way crude oil collars, which have not
       been designated as cash flow hedges for accounting purposes. As
       of March&amp;#160;31, 2011, the fair value recorded for these
       contracts was approximately $2&amp;#160;million.
   &lt;/div&gt;

       &lt;b&gt;&lt;i&gt;Interest rate swaps:&lt;/i&gt;&lt;/b&gt;&amp;#160;&amp;#160;The interest rate
       hedges we had outstanding as of March&amp;#160;31, 2011 effectively
       swap floating rate for fixed rate, taking advantage of lower
       borrowing rates in existence at the time of the hedge
       transaction as compared to the date our original debt
       instruments were executed. As of March&amp;#160;31, 2011, we had
       $377&amp;#160;million in notional debt outstanding related to these
       swaps, which cover certain interest payments through August
       2016. The notional amount decreases over time to match scheduled
       repayments of the related debt.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;

       All of our outstanding interest rate swap contracts qualify as
       cash flow hedges in accordance with the &lt;i&gt;Derivatives and
       Hedging &lt;/i&gt;topic of the Codification. Since all of the critical
       terms of our swap agreements match the debt to which they
       pertain, there was no ineffectiveness relating to these interest
       rate swaps in 2011 or 2010, and all related unrealized losses
       were deferred in accumulated other comprehensive income. We
       recognized approximately $2&amp;#160;million in additional interest
       expense as the related interest payments were made during each
       of the three months ended March&amp;#160;31, 2011 and 2010.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;

       Any outstanding derivative instruments expose us to credit loss
       in the event of nonperformance by the counterparties to the
       agreements, but we do not expect that any of our four
       counterparties will fail to meet their obligations. The amount
       of such credit exposure is generally the fair value of our
       outstanding contracts. To manage credit risks, we select
       counterparties based on credit assessments, limit our overall
       exposure to any single counterparty and monitor the market
       position with each counterparty. Some of our agreements require
       cash deposits if market risk exposure exceeds a specified
       threshold amount.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;

       The financial derivative instrument agreements we have with our
       counterparties may require us to fund all, or a portion of,
       outstanding loss positions related to these contracts prior to
       their scheduled maturities. The amount of collateral posted, if
       any, is periodically adjusted based on the fair value of the
       hedge contracts. Our policy is to offset the liabilities
       represented by these contracts with any cash collateral paid to
       the counterparties. We did not have any collateral posted
       related to our outstanding fuel hedge contracts at
       March&amp;#160;31, 2011 or December&amp;#160;31, 2010. We had
       $21&amp;#160;million and $30&amp;#160;million posted in collateral
       related to our interest rate derivatives which offset the hedge
       liability in other current liabilities at March&amp;#160;31, 2011
       and December&amp;#160;31, 2010, respectively.
