Day of the Dead (Día de los Muertos), early November, is the primary event affecting travel to Benito Juárez International Airport (MEX). Visitors flock to Mexico City, Oaxaca, and nearby sites for traditional festivities, increasing demand and possibly fares during Nov 1–3. In the U.S., late-November Thanksgiving travel may also raise passenger volume at McGhee Tyson Airport (TYS). For travelers on the TYS–MEX route, book accommodations and transfers early if attending events, and allow extra airport transit time. CTA: If you plan to visit Mexico City for Day of the Dead, secure flights from McGhee Tyson Airport (TYS) to Benito Juárez International Airport (MEX) and reserve tours in advance.
