@P365 @MikeBKY For situations where an airliner was rerouted and forced to land in a State that does not recognize your License To Carry, one might be covered under the FOPA
Firearms Owners Protection Act of 1986 aka “The Peaceable Journey Law”
This act allows a person to transport a firearm through states in which he or she does not hold a valid permit, as long as he or she may lawfully carry (whether by permit, constitutional carry, etc.) in the state of origin as well as the destination. The owner of the firearm must be in transit and not stay in the state where possession would be illegal. Furthermore, the firearm must be unloaded and contained in a locked box or out of the driver’s reach, unless state law allows otherwise. In some states, the drivers must pass through the state without stopping, and in others only short stops are tolerated.

Even this could get more complicated for situations where the airline puts someone up in hotel for a night because their next available flight is the following day.
Would it be possible that the airport keep the gun locked up in their “armory” (if that even exists) until the next flight ensues?
I’m not an attorney, but it does seem that FOPA would protect those passengers who unintentionally land in States that don’t honor reciprocity.
