Stop with the fake cheerfulness and the too often expressed sentiment that all you care about is our safety. Bull…. You use that as an excuse to keep us cowering in our seats. How about you go back to the old standby of telling the truth… like why you overbook, why you are delayed, why we don’t get vouchers for your screwups.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Flight crew and flight were good. But it departed two hours late.

They were friendly, efficient and got our bags to us so fast at the end of the flight.

Amazing. They work with my disabilities with such kindness, attention, wnd diligence. They make it easy for those of us who need a little more extra care.

Quick and easy and nice flight with nice flight crew.

We were traveling with four adults two children. The boarding crew helped seed us all together quick flight from Sacramento to Boise, seamless.

I love having assigned seats and being able to check bags at the gate, if needed. Both are super-helpful when traveling with a toddler!!!

Crew and service were great! Boarding was quick and smooth.

Friendly crew. Snacks were carb-heavy. Flight was quite delaye

the flight was significantly delayed. Not much was done by the airline to compensate passengers

Boarding now takes twice as long since going with assigned seats.

Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.

Flight boarded 2.5 hours late (my second southwest flight of the day with late departure), the gate agent was grumpy and unhelpful. Said she was "tired so we aren't going to follow normal boarding order". No complaints about the actual flight crew.

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Southwest has been a nightmare. Delayed flights, missed connections, systems down. Never again am I flying southwest.

had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.

The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

Requested an aisle seat at the gate and got it. The staff so friendly

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

more room in seats, larger snacks, more comms with delays

Gate agent and flight attendants were efficient, but more stern than warm.

The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!

Seemingly unnecessary delays were compounded by a lack of communication from the flight crew which turned a four hour delay into an overly stressful experience.

I think the crew makes way too many announcements that are: 1) hard to hear in some cases and 2) repetitive. This detracts from entertainment and concentration if working or reading.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

One of my checked luggage was damaged. Cracked on the top by the handle.

I have been flying united for a long time but now I’m done

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Wifi is very frustrating - could not connect and therefore unable to work on the trip

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

Excellent. I had a medical emergency on flight SNA-ORD and the attendants were very helpful.
