Dear Ms. Cvrkel:

By letter dated December 10, 2012, the staff of the Securities and Exchange Commission (the “Staff”) provided certain comments to the annual report on Form 20-F filed on April 30, 2012 by the Central North Airport Group (Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., or the “Company”).

The Company is in receipt of the Staff’s comment letter and is working to prepare a response.  However, the Company is not able to respond within the requested ten business day deadline included in the comment letter.  Therefore, in accordance with our U.S. counsel’s discussion with Ms. Jean Yu earlier today, the Company respectfully requests an extension to respond to the Staff’s comment letter during or before the week of January 14, 2013.

If you have any questions or require any additional information with respect to the above, please do not hesitate to contact our U.S. counsel Jorge U. Juantorena at Cleary Gottlieb Steen & Hamilton LLP at (212) 225-2758.
