After spending most of my night sick, we received a phone call from crewing telling us that three of our flight attendants were in the hospital from food poisoning. Another delayed flight but a blessing for me, more time to sleep and recover from my restless night. It was 10:30 a.m. and we started preparing the plane to fly to Stockholm. Just as we had already boarded the passengers we received a phone call letting us know we didn't have a permit to fly over Turkey. So, after 5 hours waiting in Iraq we finally received the permit and flew the plane to Stockholm.
