SUMMARY ORDER

Skyline Travel, Incorporated (NJ), Skyline Travel, Incorporated (TX) and Aby George (together, “Skyline”) appeal from the March 30, 2011 final judgment of the United States District Court for the Southern District of New York (Swain, J.) dismissing its action alleging negligence, antitrust violations, breach of good faith and fair dealing, and tortious interference with contract claims pursuant to Fed.R.Civ.P. 12(b)(6). We assume the parties’ familiarity with the underlying facts, procedural history, and specification of issues for review.

Skyline argues that Emirates owes them a legal duty of care based on the “unique bond between them and defendant created by a history of contracts, supporting the existence of a legal duty based on the relationship of the parties.” However, as the district court correctly determined, Emirates owed Skyline no duty of care. The two were parties to an at-will, noncon-tractual business relationship. There is no claim sounding in negligence for refusing to do business with another party, so long as the reason for doing so is not illegal. See, e.g., House of Materials, Inc. v. Simplicity Pattern Co., 298 F.2d 867, 872 (2d Cir. 1962) (“each business enterprise must be free to select its business relations in its own interest”); Turner Constr. Co. v. Seaboard Surety Co., 98 A.D.2d 88, 90-91, 469 N.Y.S.2d 725 (1st Dept. 1983) (“The privilege to refuse to deal exists regardless of *481 the actor’s motive for refusing to enter business relations with the other and even though the sole motive is a desire to harm the other.”) (internal quotation omitted). Emirates needed no reason to end its relationship with Skyline, and owed Skyline no duty to investigate prior to refusing to do business with it any longer.

Skyline also fails to state a valid antitrust claim because it failed to adequately identify the relevant market. Skyline defines the relevant market as “passenger air transportation and related services for New Jersey residents of Indian or Pakistani ethnicity who desired to fly on Emirates between JFK airport in New York, New York and various cities in India and Pakistan, especially in one-stop flights.” This market definition fails to include “all products reasonably interchangeable by consumers for the same purposes.” City of New York v. Group Health Inc., 649 F.3d 151, 155 (2d Cir. 2011)(internal quotation omitted). Where, as here, the complaint “limit[s] a product market to a single brand, franchise, institution, or comparable entity that competes with potential substitutes” or fails to provide a “plausible explanation as to why a market should be limited in a particular way,” the complaint is properly dismissed. Todd v. Exxon Corp., 275 F.3d 191, 200 (2d Cir. 2001); see also Global Discount Travel Seros. LLC v. Trans World Airlines. Inc., 960 F.Supp. 701, 705 (S.D.N.Y. 1997).

We have examined the remainder of Skyline’s claims and find them to be without merit. Accordingly, the judgment of the district court hereby is AFFIRMED.
