108 See 49 C.F.R. § 1560.1 (2015) (enabling the “TSA to operate a watch list matching program known as Secure Flight, which involves the comparison of passenger and non-traveler information with the identifying information of individuals on Federal government watch lists”).

109 Adamsons v. Am. Airlines, Inc., 444 N.E.2d 21, 24 (N.Y. 1982) (finding that the airline permissibly refused passage to individual in extreme pain due to undiagnosed, mysterious illness).

110 In the case of a passenger complaining of discrimination based on 14 C.F.R. § 382.21(a), no private right of action exists to the refused passenger. Violations of the Act generally will result in an investigation by the Department of Transportation and possibly the imposition of fines against the airline. See, e.g., Boswell v. Skywest Airlines, Inc., 361 F.3d 1263, 1265 (10th Cir. 2004) (concluding that the “ACAA [Air Carriers Access Act] establishes certain administrative remedies but not a private right of action”). The Eleventh Circuit held that the Air Carriers Access Act (ACAA), 49 U.S.C. § 41705, does not create a private right of action for disability discrimination by the airlines. Love v. Delta Air Lines, 310 F.3d 1347, 1349 (11th Cir. 2002) (discerning “no congressional intent to create [] a private right of action” under the ACAA).

111 See generally Abdullah v. American Airlines, Inc., 181 F.3d 363, 365 (3d Cir. 1999) (“[D]espite federal preemption of the standards of care, state and territorial damage remedies still exist for violations of those standards.”); Nettels, John C. Jr. & Irby, Jerrick L., Standard of Care Preemption in Aviation Litigation: Halting Steps to a Coherent Analysis, 76 J. Air L. & Com. 327, 337 (2011)Google Scholar (arguing that “courts are likely to apply a presumption against finding express preemption under any of the relevant federal aviation statutes”).

112 49 U.S.C. § 40120(c) (2012). Some courts have interpreted the savings clause to indicate a general congressional intent not to preempt state-law tort suits against airlines. See, e.g., Gilstrap v. United Air Lines, Inc., 709 F.3d 995, 1004 (9th Cir. 2013) (noting that the court had “in several instances held that state-law personal-injury claims are not displaced by the FAA”); Martin ex rel. Heckman v. Midwest Exp. Holdings, Inc., 555 F.3d 806, 808 (9th Cir. 2009) (finding that for field preemption to exist, the court “must infer that Congress intended to exclude all state law personal injury suits from the area of air traffic travel, even though it didn’t say so,” and that the “FAA betrays no such intention.”); Taj Mahal Travel, Inc. v. Delta Airlines, Inc., 164 F.3d 186, 194 (3d Cir. 1998) (“[T]he continued existence of statutorily mandated liability insurance coverage is strong evidence that Congress did not intend to preempt state tort claims.”). This tort analysis is distinct from two other express preemption provisions: 49 U.S.C. § 41713 (preempting claims “related to a price, route or service”), and 49 U.S.C. § 40101 (providing a statute of repose for product liability claims against airplane manufacturers).

113 Compare Abdullah, 181 F.3d at 364 (finding that state law claims exist for violation of federal standards in a claim brought by passengers injured during flight as a result of turbulence) with French v. Pan Am Express, Inc., 869 F.2d 1, 1 (1st Cir. 1989) (finding that federal aviation employment policies preempted state statute regulating drug testing for employees).

114 See, e.g., Summers v. Delta Airlines, Inc., 805 F. Supp. 2d 874, 880 (N.D. Cal. 2011) (finding preemption of negligence claim for failing to provide assistance while disembarking, but not for claim for failure to warn of a dangerous condition, because no specific area in FAA covered this type of claim); Peterson v. Continental Airlines, Inc., 970 F. Supp. 246, 250-51 (S.D. N.Y. 1997) (refusing to extend preemption to a claim that fell within the airline’s standard of conduct as a “service” under 49 U.S.C. § 41713 because there was a dispute about the reasonableness of the service provided).

115 See 28 C.F.R. § 104 (2002); see also 28 C.F.R. § 104 (2011) (incorporating the James Zadroga 9/11 Health and Compensation Act of 2010 (Zadroga Act), Title II of which reactivates the September 11th Victim Compensation Fund of 2001).

137 See, e.g., Bragdon v. Abbott, 524 U.S. 624, 655 (1998) (finding that HIV-positive status is a disability).

138 Similarly, see Pandemic Preparedness In The Workplace And The Americans With Disabilities Act, U.S. Equal Employment Opportunity Commission, http://www.eeoc.gov/facts/pandemic_flu.html [https://perma.cc/YG68-YZ6R] (last updated Oct. 9, 2009) (“May an employer covered by the ADA and Title VII of the Civil Rights Act of 1964 compel all of its employees to take the influenza vaccine regardless of their medical conditions or their religious beliefs during a pandemic? No. An employee may be entitled to an exemption from a mandatory vaccination requirement based on an ADA disability that prevents him from taking the influenza vaccine. This would be a reasonable accommodation barring undue hardship (significant difficulty or expense).”).

139 Specifically, 49 U.S.C. § 40127 (2012) provides that an “air carrier or foreign air carrier may not subject a person in air transportation to discrimination on the basis of race, color, national origin, religion, sex, or ancestry.” 49 U.S.C. § 41310 (2012) prohibits air carriers and foreign air carriers from unreasonably discriminating against any person in foreign air transportation, and 49 U.S.C. § 41702 (2012) requires that U.S. carriers provide safe and adequate transportation. Finally, 49 U.S.C. § 41712 (2012) prohibits unfair and deceptive practices by air carriers.

140 See, e.g., Letter from Peggy R. Mastroianni, EEOC Legal Counsel, to the public (Mar. 5, 2012), http://www.eeoc.gov/eeoc/foia/letters/2012/religious_accommodation.html [http://perma.cc/E6JK-7JJJ] (“The Commission and courts have consistently found that Title VII defines religion very broadly to include not only traditional, organized religions such as Christianity, Judaism, Islam, Hinduism, and Buddhism, but also religious beliefs that are new, uncommon, not part of a formal church or sect, only subscribed to by a small number of people, or that seem illogical or unreasonable to others.”).

141 See Zucht v. King, 260 U.S. 174, 176-77 (1922) (rejecting an equal protection challenge to a school vaccination mandate: “A long line of decisions by this court … also settled that in the exercise of the police power reasonable classification may be freely applied, and that regulation is not violative of the equal protection clause merely because it is not all-embracing.”). For a more recent application of this doctrine, see Workman v. Mingo Cty. Bd. of Educ., 419 F. App'x 348, 355 (4th Cir. 2011) (rejecting the claim that state vaccination mandate infringed on religious liberty).

142 Prince v. Massachusetts, 321 U.S. 158, 166-67 (1944). Similarly, see Jacobson v. Massachusetts, 197 U.S. 11, 35 (1905) (finding that a state has police power to mandate vaccination, which overrides an individual’s liberty interest). There is rich literature on the continuing vitality of Jacobsen. See Gostin, Lawrence O., Jacobson v. Massachusetts at 100 Years: Police Power and Civil Liberties in Tension, 95 Am. J. Pub.
