MichaelFlew with SouthwestLAS-SANJan 2025
It’s a quick flight and sometimes turbulent leaving the desert. You may not get drinks service due to the brief flight time and safety measures.
LouieFlew with SouthwestLAS-SANApr 2024
Honestly, Southwest's short flight time and 2 free checked bags make it the best deal out there!
JosephFlew with DeltaLAS-SANFeb 2024
Your seat selection may be changed at check-in and you may not be able to change your seat to what you originally selected while booking so be aware of this possible issue.

No leg room AT all extremely uncomfortable flight water even cost 5 dollars

Seats are very uncomfortable pls make your seats comfortable pls pls pls

I was comfortable because I upgraded. I would not have been comfortable in economy. It was a short flight so there was limited food service and no inflight entertainment.

Seats were surprisingly comfortable, and crew was polite. I did not like the baggage fee prices, the minimal amount of flight choices for my area and the difficulty of the self service bag drop.

Delayed fight LAS to LAX. OK, fog in LA, not your fault. But all your staff, onboard in in lounge, speak so fast, enunciate so poorly and often have a accent that it is impossible to understanding anything they are saying.

It was smooth. It’ll always be annoying that nothing is included in the booking (seats and bags particularly).

No carry on available to purchase at any point, charged for water, no power to charge phone. Other discount airlines have this.

I could not print my boarding passes and had to see an agent. However, the agents were very friendly and helpful.

It was cancelled unexpectedly so we rented a car and drove home.

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).
