So sorry about your mom and it's no fun to be given the run-around at the airport. Please know that the locals can go through the GCC line and so of course they never have to wait. In defense of Qatar Airways I was recently in Abu Dhabi and due to many factors (including getting lost on the way to the airport and airport personnel directing me to the wrong place 2 times) I arrived exactly 20 minutes before my flight was to leave! Everything was closed! Luckily someone nice took me to the privilege area and even though they said they would simply have to book me on a flight 4 hours later, managed to get me onto my flight on time. They were awesome. I was so impressed.
