Chicago (Midway) to Burbank Ca. , to Oakland to Honolulu Back to Oakland to Chicago Midway. The flight crews were very nice and attentive to all passengers. Coming home, (Oakland to Chicago), there was very low cloud coverage. An instrument landing was needed and performed very well. I did not see the ground until we were about to touchdown. "Great pilot(s)". Love Southwest hope they will soon go to Knoxville.
