Sorry to laugh...  I just bought tickets from QA for my family in Los Angeles...  The lady on the phone said they "just need to pick them up at the local office... in Washington DC!"  Sure, in Qatar you can drive across the country in 2 hours, but thats 5000 km!!  Anyway, I eventually picked up the e-tickets at a QA office here (long story) and paid with my credit card....

Here's what they told me: if you purchase online with your card, you need to go to a local office and fill out a form...  I purchased them over the phone so I just needed to pick them up and no extra form needed (thats what the people in the office told me, on the phone they said I needed a form)...

You would think QA staff would know their policies, but that's expecting too much, isn't it?
