Air France flight diverted to Montreal after Ebola exposure fears and U.S. restrictions

On 2026-05-21, Air France flight 378 bound for Detroit was diverted to Montreal after U.S. restrictions related to Ebola exposure risk led authorities to deny boarding/entry to a passenger. According to CBP and Air France, the passenger had recently been in East Africa and was escorted off the aircraft after landing. The action reflected implementation of Ebola-related travel restrictions rather than a new outbreak declaration.
