Friend of mine just bid Captain on it in SLC. Currently an SLC 320 FO. He says the 737will be growing slowly over the next two years. According to him the pilots have been told that the base will grow significantly once the new airport comes online in 2020.

Also my soon-to-be daughter-in-law is a Delta FA. She said the FA's have been told the same thing. SLC is to have a lot of new flying.

As they both also said, that and three bucks will get you a cup of coffee...
