I gave up and just booked via a travel agent in the UK who I found here on Flyertalk (bazza1603). I went to the Qatar ticketing office in IAH and was told if I want to book cash I need a passport scan of uncle's passport, which I don't have. If I booked credit card the lady said I may or may not get an email to verify the credit card, and if I didn't, he may or may not be asked at check in. Just too much uncertainty so I just paid the 20 pounds and had the TA pay Qatar directly. Also they mailed the ticket to his house and have a UK phone number in case anything goes wrong.
