Re: Erratum to Motion for Leave to File and Response ofVirgin America Inc;, filed March 30, 2012, in Docket DOT-OST-2012-0029

Dear Ms. Wright: Due to a typographical error, the first complete sentence on Page 2 of the abovecaptioned filing incorrectly states "CFM53" engines instead of "CFM56" engines. Please replace Page 2 ofthe filing with the enclosed Erratum page, which contains the correct text in bold type.

cc: All parties listed onthe attached service list. Very truly yours,

### Erratum- April, 2, 2012 Virgin America will likely be required to restrict sales, further decreasing available seats on what is already the second smallest aircraft proposed in this proceeding. Virgin America is, in fact, and as reported in the Flight Global article, currently in the
process ofupgrading the thrust for the CFM56 engines on its A319 aircraft. However, Alaska's suggestion that Virgin America might somehow be required to "restrict sales" of seats in the DCA-SFO market is entirely without merit. The upgrade that Alaska has put at issue requires the straightforward installation of an engine data plug and identification plate, accomplished during the course of overnight maintenance visits. Virgin America has already initiated the
process ofmodifying its flight and maintenance manuals for the upgrade, with the upgrade itself scheduled to be completed for six Virgin America A319 aircraft, including the three aircraft that would be used for Virgin America's proposed DCA-SFO flights, by June 30, 2012, well before the date onwhichVirgin America wouldbegin operating such flights.

March 30, 2012 Respectfully submitted,
