How do you put a signiture on the flight ii?

To put a signature on a flight itinerary, you typically need to access the document in a digital format, such as a PDF. Use an electronic signature tool or app that allows you to upload the document, add your signature, and then save or export the signed version. If you are working with a physical copy, you can simply print the itinerary, sign it by hand, and then scan or photograph it to keep a digital record.
