Mount Kanlaon's eruption on 3 June reached Alert Level 2 that resulted in the cancellation of 74 domestic flights from NAIA and vice versa, as well as other nearby domestic hubs.

The Civil Aviation Authority of the Philippines (CAAP) and the Manila International Airport Authority (MIAA) announced the cancellation of 74 domestic flights from Manila along with various domestic hubs, as of 8:30 a.m on Tuesday, 4 June 2024, due to the eruption of Mt.
