I am flying to Japan via United, and their Travel Ready Center is rejecting my vaccine documentation even though I am fully vaccinated. What's wrong?

    What sort of rejection message did you receive? For example, are they saying that your documentation is illegible? That it is missing required doses? That it is a forgery? Commented Oct 22, 2022 at 20:36

    @RobertColumbia as far as I remember United doesn't provide an error message. It's basically "yes" and "no". When I had an issue I needed to call them

You may notice that your first and middle name is merged in the name field they've forced upon you. Bad programmers.

This will obviously not match a US COVID-19 Vaccine Record Card, and so your card will be rejected.

To solve this, in the United Airlines app, upload your vaccine documentation in your profile > TSA Precheck®️ and travel documents > COVID-19 Vaccine Documentation

This one does not merge your first and middle name together. Go back to the Travel Ready Center and upload your vaccine documentation again. This time, a pop-up will appear, allowing you to use the documentation you previously uploaded, without uploading a new file. Documentation verification should pass this time, allowing you to check-in using the app.

Failing this, you need to physically go to check-in or the gate with your documentation and they'll sort the mess out for you

    As a programmer I feel mildly insulted. It's less the choice of programmers, and more the issue of decades (probably close to half a century) old legacy systems which did not get updated when people realized they need to handle anything but the most basic of names.

    Also as a programmer, it's imperative to test various use cases and not ship broken products while requiring their use in a mission critical application Commented Oct 25, 2022 at 15:18

    @I'llEatMyHat That's why working with names sucks. UUID's for everyone?
