Yes, for all international travel in 2026, the name on your airline ticket must match the name on your passport exactly. This include your first name, middle name(s), and last name. Security agencies like the TSA and international customs use "Secure Flight" data to compare passenger manifests against watchlists and government records; even a small discrepancy, such as a missing middle name that appears on your passport or a misspelled last name, can lead to you being denied boarding or held at immigration. If you have recently married and changed your name, you must either book the ticket in the name currently in your passport or update your passport before traveling. In 2026, many airlines allow for "minor name corrections" (up to 3 characters) for free, but major changes or legal name updates usually require a fee and the submission of legal documentation like a marriage certificate or a court order to prove your identity.
