       In February 2011, we cancelled the orders for two EMBRAER 190
       aircraft previously scheduled for delivery in 2013.
   &lt;/div&gt;

       As of March&amp;#160;31, 2011, our firm aircraft orders consisted of
       53 Airbus A320 aircraft, 51 EMBRAER 190&amp;#160;aircraft and 14
       spare engines scheduled for delivery through 2018. Committed
       expenditures for these aircraft, including the related flight
       equipment and estimated amounts for contractual price
       escalations and predelivery deposits, will be approximately
       $270&amp;#160;million for the remainder of 2011, $470&amp;#160;million
       in 2012, $535&amp;#160;million in 2013, $800&amp;#160;million in 2014,
       $925&amp;#160;million in 2015 and $1.20&amp;#160;billion thereafter.

       In March 2011, we executed a seven year agreement, subject to an
       optional three year extension, with ViaSat Inc. to develop and
       introduce in-flight broadband connectivity technology on our
       aircraft. Committed expenditures under this agreement include a
       minimum of $9&amp;#160;million through 2017 and an additional
       $22&amp;#160;million for minimum hardware and software purchases.
       Through our wholly-owned subsidiary LiveTV, we plan to partner
       with ViaSat to make this technology available to other airline
       customers in the future as well.
   &lt;/div&gt;

       As of March&amp;#160;31, 2011, we had approximately $31&amp;#160;million
       of restricted assets pledged under standby letters of credit
       related to certain of our leases which will expire at the end of
       the related lease terms. Additionally, we had $19&amp;#160;million
       pledged related to our workers compensation insurance policies
       and other business partner agreements, which will expire
       according to the terms of the related policies or agreements.
   &lt;/div&gt;

       In March 2010, we announced that we will be combining our
       Darien, CT and Forest Hills, NY corporate offices and relocating
       to a new corporate headquarters in Long Island City, NY. In
       September 2010, we executed a 12&amp;#160;year lease for our new
       corporate headquarters in Long Island City. Other than this
       commitment, we do not have any material obligations as of
       March&amp;#160;31, 2011 related to this corporate relocation, which
       is currently scheduled to commence in 2012.
   &lt;/div&gt;
