Mexico City (via MEX): Level 2 — Exercise Increased Caution. Neighbouring Morelos are higher-risk (up to Level 3). Check the state-specific advisory for your exact destination. This is a US State Department safety perspective, not an entry or boarding rule — it doesn't affect whether you can board, only what to be aware of on the ground. Travellers from other countries should also check their own government's advisory.

Mexico (MX) requires every traveller to submit the Mexico Tourist Card (FMM) for entry — best done a few days before departure rather than in the airport queue. Without it, expect to be pulled aside at the border or denied boarding. Apply at: https://www.inm.gob.mx/fmme/publico/en/solicitud.html
Mexico requires proof you'll leave before they let you in. At check-in the airline often asks for this — without it, they can deny boarding because the carrier becomes liable for flying you back.

Have whichever you choose printed or on your phone before you reach the counter.
