Just tried to check in online with Qatar, fly Sunday morning, but the damn system won't let me do it!!!! All goes well till I put my grand daughters date of birth in, and it comes up not valid date of birth. She's on the booking as an adult but she's only 8, did phone them couple of weeks ago because had same problem doing the API. Proper peed off. Will I be able to do it over the phone tomorrow anybody know?? Can't find anywhere open tonight to ring!
