RESOLUTION OF DISPUTES

The Sabre Dev Studio site is operated by Sabre from within the United States. This Terms of Use and its performance shall be governed by the laws of the State of Texas, United States of America, without regard to conflict of laws provisions that would result in the application of the laws of any other jurisdiction. If a dispute does arise between you and Sabre, our goal is to provide you with a neutral and cost effective means of resolving the dispute quickly. Accordingly, you and Sabre agree that we shall resolve any action, claim or controversy at law or equity (a "Claim") that arises out of your use of the Sabre Dev Studio site, this Terms of Use, or the parties' relationship in connection with the Sabre Dev Studio site or this Terms of Use in accordance with one of the subsections below or as otherwise mutually agreed by the parties in writing. Before resorting to these alternatives, we strongly encourage you to first contact us directly to seek a resolution by contacting api-support@sabre.com since most customer concerns can be resolved quickly and satisfactorily in this manner.

  • Submission to Jurisdiction in Texas - You agree that unless otherwise mutually agreed by the parties in writing or as described in the Mandatory Arbitration subsection below, any Claims shall be brought in the state or federal courts located in Tarrant County, the State of Texas, United States of America. Unless otherwise prohibited by applicable law, any Claim must be brought within two (2) years from the date on which such Claim arose or accrued.
  • Mandatory Arbitration - Any Claim where the total amount in controversy is less than US$10,000 shall be resolved via binding, non-appearance-based arbitration initiated through the American Arbitration Association ("AAA"). The AAA Rules are available online at www.adr.org or by calling the AAA at 1-800-778-7879. AAA and the parties must comply with the following rules: (a) the arbitration shall be conducted by telephone, online and/or be solely based on written submissions, the specific manner shall be chosen by the party initiating the arbitration; (b) the arbitration shall be conducted by an arbitrator in Tarrant County, Texas who is approved or otherwise affiliated with the AAA; (c) the arbitration shall not involve any personal appearance by the parties or witnesses unless otherwise mutually agreed by the parties in writing; (d) the arbitrator may award injunctive or declaratory relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party's individual claim; (e) unless otherwise mutually agreed by the parties in writing, the arbitrator may not consolidate more than one person's claims, and may not otherwise preside over any form of a representative or class proceeding; and (f) any judgment on the award rendered by the arbitrator may be entered in any court of competent jurisdiction. If subparagraph (e) above is found to be unenforceable, then the entirety of this Mandatory Arbitration provision shall be null and void. YOU UNDERSTAND AND AGREE THAT, BY ENTERING INTO THIS TERMS OF USE, YOU AND SABRE ARE EACH WAIVING THE RIGHT TO A TRIAL BY JURY OR TO PARTICIPATE IN A CLASS ACTION WITH RESPECT TO THE CLAIMS COVERED BY THIS MANDATORY ARBITRATION PROVISION.
  • Improperly Filed Claims - All Claims you bring against Sabre must be resolved in accordance with this Resolution of Disputes Section. All Claims filed or brought contrary to the Resolution of Disputes Section shall be considered improperly filed and void. Should you file a Claim contrary to the Resolution of Disputes Section, Sabre may recover attorneys' fees and costs, provided that Sabre has notified you in writing of the improperly filed Claim, and you have failed to promptly withdraw the Claim.

ATTORNEY'S FEES

If Sabre takes any action to enforce this Terms of Use, and such Claim is not resolved pursuant to the Mandatory Arbitration provision under RESOLUTION OF DISPUTES, above, Sabre will be entitled to recover from you, and you agree to pay, all reasonable attorney's fees and any costs of litigation, in addition to any other relief, at law or in equity, to which Sabre may be entitled. Moreover, you agree that Sabre may debit your credit or debit card or charge you for any such amounts.

INJUNCTIVE RELIEF

You acknowledge that a violation or attempted violation of any of this Terms of Use will cause such damage to Sabre as will be irreparable, the exact amount of which would be impossible or difficult to ascertain and for which there will be no adequate remedy at law. Accordingly, you agree that Sabre shall be entitled as a matter of right to seek an injunction from any court of competent jurisdiction, restraining such violation or attempted violation of these terms and conditions by you, or your affiliates, partners, or agents, without having to post a bond or other security.
