Pat, I think that is true about diversions especially because of high winds as this happened to us a couple of years ago trying to land in Ottawa from Cuba. After three tries, we were diverted to Toronto and sat on the runway there for three hours waiting for the weather conditions in Ottawa to change.
There were a couple of passengers that had a panic attack and had to be removed from the plane by security and medics. They said they would not get back on the aircraft and were going to rent a car and drive from Toronto to Ottawa. I guess they were not convinced that driving in a storm was more dangerous than flying!
