Lodging IS covered if it is incidental to the trip. If you need to stop to sleep, you are covered under FOPA.
Incidental to the trip means if you stop to sleep on a trip between MA and NY, no you aren't covered.
But if you stop to sleep on a trip between MA and TX, you are covered.
Without reading about that specific instance, I can't comment. Could he have headed straight home after a flight? Did he instead CHOOSE to stay at a NJ airport?
Also, its pretty well established that Port Authority airports in NY and NJ ignore FOPA and let you sort it out in the courts.
Sorry, but the 3rd Circuit Court of Appeals disagrees with you.
The case everyone is talking about (mostly incorrectly), is
Revell v. Port Authority of New York & New Jersey, 598 F.3d 128 (3rd Cir. 2010)
Basic facts: Revell was flying to PA, via Newark. Gun checked properly in his luggage. Missed his connection to PA. Airline put everyone on a bus to PA, but Revell got off the bus to find his luggage, and then missed the bus. Got his luggage, stayed overnight at the Airport Sheraton, and when he went to check in for his flight the next day, got busted. He tried to sue the Port Authority for his arrest, claiming denial of rights under the color of law. He lost.
Regarding his claim that 18 U.S.C. § 926A. (FOPA) covered him during his hotel stay, here's what the Court said (emphasis added):
"18 U.S.C. § 926A. It is clear from the statute that a person transporting a firearm *136 across state lines must ensure that the firearm and any ammunition being transported is not "readily accessible or... directly accessible from the passenger compartment of [the] transporting vehicle."
Id. Looking solely at the allegations of Revell's original complaint,
it is also clear that what happened here does not fall within § 926A's scope because his firearm and ammunition were readily accessible to him during his overnight stay in New Jersey.
Revell attempts to invoke the protection of the statute by alleging that "[d]uring the transportation of the firearm, neither the firearm nor the ammunition were readily accessible or directly accessible from the passenger compartment of the aircraft or the bus [that he took to the hotel]." (App. at 25.)
But only the most strained reading of the statute could lead to the conclusion that having the firearm and ammunition inaccessible while in a vehicle means that, during the owner's travels, they can be freely accessible for hours at a time as long as they are not in a vehicle. The complaint reveals that Revell's luggage containing the firearm was, in fact, available to him while he was at the hotel. He alleged that, "[a]fter retrieving his bag, because there were no more connections to Allentown until 9:45 a.m. the following morning ..., [he] went directly to, and stayed the night at, the Airport Sheraton Hotel." (App. at 23.) He further alleged that he returned with his luggage directly to the airport the next day and that a TSA agent, after x-raying the luggage, opened it with a key that Revell gave him. Taking those facts as true,
it is clear that the gun and ammunition were readily accessible to Revell during his stay in New Jersey and, thus, by the allegations of his own complaint, he was not within the scope of § 926A. Dismissal of the § 926A claim was therefore proper.[13]"
The Court held that the key is whether or not the gun is "readily accessible to you" while in the "bad" state, and staying overnight at a hotel clearly makes the gun "readily accessible," and FOPA does not apply.
