Air India's last name policy requires that the name on the ticket exactly matches the name on your valid government-issued ID or passport. If your last name is missing, combined with your first name, or has minor spelling errors, you may request a correction. However, Air India does not allow complete name changes or ticket transfers. Minor corrections to the last name must be supported by official documents and should be requested at least 48 hours before departure. You can make these corrections by contacting Air India customer service or visiting a local ticket office. It’s essential to review your ticket details immediately after booking to ensure your name, especially the last name, is accurate to avoid boarding issues.
