on the third leg, about 30 minutes out, there was smoke in the cockpit. We had to turn around and head back to SLC. that was the bad part. the good part was that we were safe and Delta handled it in a first class way. We did not have to wait hour after hour. it was late so they immediately took us to a nice hotel, provided a nice breakfast the next morning, took us back to the airport and made sure we had money for a good lunch. I am now a Delta Fan.

on the third leg, about 30 minutes out, there was smoke in the cockpit. We had to turn around and head back to SLC. that was the bad part. the good part was that we were safe and Delta handled it in a first class way. We did not have to wait hour after hour. it was late so they immediately took us to a nice hotel, provided a nice breakfast the next morning, took us back to the airport and made sure we had money for a good lunch. I am now a Delta Fan.
