What if a passengers boarding pass and ID do not match exactly?
Secure Flight and travel document checking are both critical security functions, yet they serve different purposes at different points in the security process. Secure Flight is a behind-the-scenes watch list matching process that takes place before checkpoint screening. Secure Flight asks that passengers enter their names as they appear on their government ID and passengers should strive to stay consistent between the name on their ID and the information they provide when booking their reservation. Once a passenger receives their boarding pass, the Secure Flight process is already complete.
At the security checkpoint, TSA strives to ensure your identification and boarding pass are authentic and validate you are who you say you are. Small differences in the name on the boarding pass and ID, like middle initials, should not impact your travel. It is not uncommon for the information printed on boarding passes to differ slightly from the information on IDs, depending on the boarding pass printing practices of individual airlines.
