Haven't had any deaths on my flights, but this afternoon did experience my first medical emergency. Fortunately it was during boarding and we were still at the gate at IAH, when a passsenger in the back suddenly had a seizure. Boarding was stopped, and paramedics arrived in a few minutes. I was in F and could hear the flight attendant that were still at the front of the plane talking about it with the captain and giving him updates while the other flight attendants and a passenger who was a nurse attended to the passenger. After the paramedics arrived they took him off the plane, boarding resumed, and we departed less than 30 minutes late. By this time the weather around IAH was getting bad quickly, but we did get to takeoff and after a very bumpy flight arrived at AUS a half hour later.
