The airline is debuting what it says is the first ever subscription airline service in the U. S.

Members can sign up and pay a monthly fee starting at $49 and then fly up to 24 roundtrip flights per year. The price goes up depending on how many flights you want access to every year and if you want the option of same day booking.

For now, it'll only work for flights in the West from places like Las Vegas, Phoenix, LA, and Sacramento and only in economy class.
