Schedule TO - Exhibit (a)(1)(A)     U.S. Offer to Purchase

Forward Looking Statements, page 4

   1. The safe harbor for forward looking statements in the Private Securities
      Reform Act does not, by its terms, apply to statements made in connection
with a tender
      offer. Please revise to clarify, or to delete the reference to the Reform

Purpose of and Reasons for the U.S. Offer; Plans for OMA following the U.S.
Offer, page 23

   2. We note the statement here that    [w]e have from time to time met, and
will continue to
      meet, with potential counterparties to [potential synergistic
transactions], although to date
      none of the discussions have resulted in definitive agreements, plans or
      Pursuant to Item 1006(c) of Regulation M-A, please describe in additional
detail the

          plans, proposals or negotiations    that might result in one of the
       transactions listed.

Withdrawal Rights, page 38

   3. Here and throughout the Offer to Purchase where you discuss shareholders
  ability to
      withdraw tendered shares, note that shareholders who tender in the U.S.
Offer may
      withdraw their shares at any time after the 60th day from the
commencement of the
      Offer, pursuant to Exchange Act Section 14(d)(5).

Source and Amount of Funds, page 39

   4. We note that you will pay for tendered shares with proceeds from a
financing agreement
      that will be signed and consummated    on or prior to the Expiration
Date.    When the
      terms of the financing for the Offer are set, you must amend to provide
the disclosure
      required by Item 7 of Schedule TO and Item 1007(a) of Regulation M-A. See
      comment below regarding the Financing Condition, and the timing of
satisfaction of that
      condition with respect to the Expiration Date.

Conditions of the Offer, page 56

   5. All Offer conditions must be satisfied or waived as of or before the
Expiration Date.
      Revise the first paragraph of this section to clarify.

   6. Revise to clarify what is meant by a    limitation on prices    for
purposes of these Offer

   7. We note the Financing Condition on page 57. In our view, when this
condition is
      satisfied and the Offer becomes fully financed, a material change will
occur in its terms,
      requiring that the Offer remain open for at least five business days
thereafter and further
      requiring an amendment to the tender offer materials with additional
disclosure (see our
      comment above). Please confirm your understanding in your response

   8. Refer to the last paragraph in this section and the statement that
each such right shall be
      deemed an ongoing right which may be asserted at any time and from time
to time.
      Please note that if an event occurs that    triggers    an Offer
condition while the Offer is
      pending, the Offerors must promptly inform target shareholders whether
they will waive
      the condition and proceed with the Offer, or assert it to terminate.
Please revise this
      language accordingly.


   9. We note that the Offerors are affiliated entities who currently own 15%
of Grupo
      Aeroportuario and that this is a partial offer that will result in them
owing up to 39.7% of

       that target company if fully subscribed. While the combined Offers are
not expected to
       result in a going-private transaction, please confirm that this is not
the first step in a series
       of transactions that may have that effect. See Rule 13e-3(a)(3)(i)-(ii).
