In the foreseeable future a reservation of mine has a flight on AlaskaSkyWest. I could SDC to AlaskaHorizon leaving an hour later. Looking through a microscope would you happen to have a preference? I have read that some minor differences may exist, such as Horizon's E175s having ovens for First Class meals, while SkyWest's may not, and SkyWest having a coat closet. SFO-LAX doesn't offer meals though, and my idle curiosity may be entertained by people in Main trying to locate the front bathroom.
