Why In The World Did The Boeing 777X Fly To Mexico?

In 2024, Mexico’s Toluca International Airport (TLC) was seen hosting Boeing 777X test flights. While the Boeing 777X was not the first aircraft to conduct flight testing at Toluca, it does appear to be uncommon for Boeing to test its aircraft there. The Boeing 777X has been flying for five years now, having first flown in 2020. Boeing had planned for it to already be in service, but the aircraft has experienced FAA certification delays.
