The plaintiff-appellant Williams was an employee of Ground Services, Inc., a division of a company which had contracted with Pan American World Airlines to perform the ground handling of its passengers’ baggage. He was injured at the Miami International Airport in the course of his employment by the alleged negligence of a Pan Am employee while they were both engaged in that process. After receiving worker’s compensation benefits from Ground Services and its carrier, Williams brought this third-party damage action against Pan Am. The trial court, however, granted summary judgment to Pan Am on the ground that it was.a “contractor” — for transportation services with its passengers — which had “sublet” part' of that “contract work” — its obligation to transport their luggage — to Ground Services. On this basis, Pan American was held immune from tort liability to Williams as a Ground Services employee under the exclusive remedy provisions of Sections 440.10,1 440.11,2 Fla.Stat. (1981). We disagree and, upon the opposite holding that Pan Am is, as a matter of law, not immune, revérse the judgment below.
Even assuming, contrary to the thrust of West v. Sampson, 142 So.2d 74 (Fla.1962) and the holding of State v. Luckie, 145 So.2d 239 (Fla. 1st DCA 1962), cert. denied, 148 So.2d 278 (Fla.1962),3 that exclusive-remedy-compensation-immunity may ever exist outside the familiar general contractor-construction job situation4 it plainly does not in this case. Two closely related, if perhaps analytically distinct reasons, compel this result. First, as in the controlling case of Florida Power & Light Co. v. Brown, 274 So.2d 558 (Fla. 3d DCA 1973), Pan Am’s “primary obligation” in transporting their luggage arises not out of its countless individual contracts, that is, the tickets, with its passengers, but from generalized statutory and common law requirements that it do so. See e.g., 49 U.S.C. § 1301, et seq., § 1374; State ex rel. Burr v. Jacksonville Terminal Co., 90 Fla. 721, 754, 106 So. 576, 584 (1925); State ex rel. Postal Tel.-Cable Co. v. Wells, 96 Fla. 591, 600, 118 So. 731, 736 (1928); Atlantic Coast Line R. Co. v. Campen Bros. Co., 114 Fla. 386, 388, 154 So. 131, 133 (1934). Indeed, Brown is a fortiori case to this one, because, in contrast, a single express written agreement to supply electricity to a shopping center was involved. Nonetheless, this court held that the primary obligation allegedly “subcontracted” to the *70plaintiffs employer was not based on the contract, but upon F.P.L.’s statutory duties as a public utility.
Second, the purportedly “sublet” work of carrying baggage was, at best, but a small, surely not indispensable portion and was thus, to use the legal term of art, merely “incidental” to the essence of the “prime contracts” — which was clearly to transport the passengers themselves. Under the now highly-buffed judicial gloss which has been placed on Section 440.10, Pan Am is not entitled to immunity for this reason as well. State v. Luckie, supra; Florida Power & Light Co. v. Brown, supra; Cork v. Gable, 340 So.2d 487 (Fla. 2d DCA 1977).
Because it is so obviously and decisively distinguishable, we need not decide whether Hart v. National Airlines, Inc., 217 So.2d 900 (Fla. 3d DCA 1969), cert. denied, 225 So.2d 533 (Fla.1969), upon which the appellee almost wholly relies,5 retains any viability whatever in the light of the later decision in Florida Power & Light Co. v. Brown, supra, and the other authorities already cited. In Hart, the airline’s duty of transporting mail arose, not by operation of law, but out of a specific, one-purpose, written contract to that effect with the United States government. Moreover, it was that very contractual purpose, to handle mail, which was the subject of the subcontract with the plaintiffs employer. Thus, both of the reasons we have identified for denying immunity because they are not present in this case were satisfied in Hart.
For these reasons, the judgment below is reversed and the cause remanded for trial.
Reversed.
