Sacrament staff are always polite and helpful. Airport is easy to maneuver and boarding is straightforward.

Delayed 5.5 hours

10.0 Wonderful
Great flight. Outstanding Service. Southwest was able to put us on a direct flight to Denver when the connection could have been affected by a later arrival to Baltimore. The direct flight was less expensive that the flight with the connection in Baltimore.

Getting worse with new changes.

4.0 Mediocre
Delays delays delays. Late taking off, late landing, wait for a gate, etc.
T
4.0 Mediocre
Internet was not functioning.

2.0 Poor
Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.
L
10.0 Wonderful
On time. Communication good. Smooth flight
P
2.0 Poor
I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.
T
6.0 Okay
Late again.
