Gentlemen:

Reference is hereby made to the above-referenced agreements (the “Agreements”).
This letter will acknowledge and evidence that American Airlines, Inc.
(“American”) is willing and hereby offers to agree, effective as of the date of
this letter and for good and valuable consideration, to the terms set forth in
Exhibit A attached hereto with respect to the provision of inflight connectivity

If Gogo is also willing to accept and agree to such terms, please evidence and
acknowledge such fact by signing both copies of this letter in the space
provided and returning one (1) copy to the undersigned. In such event, and
without the necessity of further action: the Agreements shall be deemed to be
amended to reflect such terms; and, as so deemed to be amended, the Agreements
shall be deemed to be ratified and affirmed and to remain in full force and
effect. All capitalized terms used in such terms without definition shall have
the respective meanings therefor specified in the applicable Agreement(s).

To the extent that any provision in Exhibit A is inconsistent with another
provision in any Agreement, the provision in Exhibit A shall prevail. The
parties acknowledge that pending execution of the unified agreement contemplated
by Exhibit A, due to the summary nature of certain terms set forth in Exhibit A
and the lack of defined terms therein, the parties may from time to time be
required to agree upon certain details required to properly effectuate such
terms (including by way of example notice periods or materiality thresholds) or
to reconcile such terms with other existing but not inconsistent terms of the
Agreements, and to consider other matters of contract interpretation. The
parties shall work together in good faith to reach a mutually acceptable
resolution of such issues.
