I'm trying to book a ticket online with United Airlines and it keeps asking to enter a valid date of birth.

I have tried all combinations but it won't take it, i.e m/d/y

    For us to help you figure out what's wrong with your entry, we need to know what you entered. – phoog Jun 19 '15 at 22:01

    Did you try with the "international standard" ISO-8601 form of yyyy-mm-dd? Or failing that the non-US form of dd/mm/yyyy? – Gagravarr Jun 19 '15 at 22:10
  • When I tried it, it clearly shows it should be entered as mm/dd/yyyy and indeed entering 06/19/1953 worked just fine. Are you using the US site or something else? What flag appears in the upper right corner of the page? – Nate Eldredge Jun 19 '15 at 22:23
  • Are you booking in the United States? (I'm assuming that if you were using a county-local version of the website, it might have a different date format) – mkennedy Jun 19 '15 at 23:16

    Change the browser :) – pbu Jun 20 '15 at 8:21

Try something with the following format: mm/dd/yyyy

Such as 10/30/1981 for 30th of October 1981.

If it still does not work, try again with different browsers, in this order:

  1. Firefox
  2. Google chrome
  3. Internet explorer (minimum version 10)

    If it still does not work, switch off computer, get a cup of coffee, switch back on, try again. If it fails, reboot again, clear cookies and try anew. (General internet trouble shooting solutions.) – Willeke Jun 20 '15 at 15:29
