Reason and duration irrelevant. A sign could be that all flights are cancelled, diverted, and delayed across the state, but likely there will be an announcement due to weather/ war/ instability/ etc. Only states with two or more international airports count, otherwise this trivial.
Resolves YES if every one of a US state's international airports are shut down at the same time, beyond regular hours. Nightly closures don't count. Smaller private and business airports don't count.
Resolves NO otherwise after close.

Update 2025-10-28 (PST) (AI summary ofcreator comment): A single international airport closing (e.g., New Orleans airport during a hurricane)would countif it is the only international airport in that state, making it "all of the international airports" in Louisiana.<- AI is wrong again! The state must have at least two international airports, so only New Orleans closing would not qualify, but New Orleans and Alexandria would qualify. My answer was about "common" closure reasons like hurricanes, not about single airport states.

1.00@IanTurner2541 yes if it's all the international airports in Louisiana (meaning Alexandria also closes bc of the hurricanes, or even if one closed for the hurricanes and the other closed for another reason at the same time). (sorry I'm late to reply! I left the site for a year)
@mariopasquato Nebraska, Arkansas, Delaware, Idaho, South Dakota and West Virginia ; I believe.
@SirCryptomind Given that applying the universal quantifier on the empty set yields true then these states already shut down all their international airports. But I see you are asking that there are at least two airports…
