Cal. Bus. & Prof. Code § 17550.37

(a) “Person aggrieved,” as used in this article, means a passenger, as defined in Section 17550.3, located in California at the time of sale, or a person located in California at the time of sale who made any payment on behalf of the passenger for air or sea transportation or travel services, who has sustained a loss as a result of the failure of a seller of travel to refund payments made by or on behalf of a passenger as payment for air or sea transportation or travel services, where a refund is due as a result of the bankruptcy, insolvency, cessation of operations, or material failure to provide the transportation or travel services purchased by the passenger, regardless of whether the passenger or a person making payment on behalf of the passenger initially contracted with that seller of travel. “Loss,” as used herein, shall be limited to losses that are incurred in a transaction with a seller of travel who, at the time of sale, was registered pursuant to Section 17550.20, and who had been a paid participant at any time during the period commencing with 18 months previous to the time of sale, and ending with the expiration of the applicable time period provided in law for the filing of a civil, administrative, or other available action under the law that is available to the person aggrieved. “Person aggrieved” shall not mean or include a passenger, or person making payment on behalf of a passenger, in a transaction where the air or sea transportation or travel services are furnished by a business entity that is located and providing transportation or travel services outside of the United States and is not in compliance with Article 2.6 (commencing with Section 17550).
(b) Any person aggrieved who files a claim for payment from the Travel Consumer Restitution Fund thereby waives his or her right to bring any action at law or equity that is against the seller of travel as to whom the claim is made and arises from the transaction that is the subject of the claim against the restitution fund. The claim form required by Section 17550.46 shall include a clear and conspicuous notice of the waiver.
(c) The waiver of rights provided for by subdivision (b) shall not apply to any claimant whose claim is denied on any of the following grounds, as set forth in the statement of decision required by subdivision (d) of Section 17550.47:
1. (1) The seller of travel had not been a paid-up participant in the Travel Consumer Restitution Fund at any time during the period of time provided in subdivision (a).
2. (2) The seller of travel was not, at the time of sale, registered pursuant to Section 17550.20.
3. (3) The claimant was not located in California at the time of sale, as required by subdivision (a).
