Had to go in the bus to board the flight. Was traveling with just a carry on, but Carry on luggage was recommended to be checked in and it took a while to come to the baggage claim.

Had to go in the bus to board the flight. Was traveling with just a carry on, but Carry on luggage was recommended to be checked in and it took a while to come to the baggage claim.

No problems at all. Thanks for the safe trip. Henry

Flight was on time, inflight service was professional and attendants were so pleasant.

Very Large person sitting next to me and taking up a lot of space including mine

There was no sense of urgency to get us to our destination on time. There’s just no such thing with this airline. It’s not my fault, they don’t have enough help. They sure as hell charge you enough for everything Nothing like being nickel and dimed to death. Money for bags money to choose a seat. You gotta be made for money to fly this airline.

App didn't check me in, lost my upgraded seat Seat didn't stay reclined Lavatory was wet/leaked on my shorts

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

Need to get on train for second flight it’s much nicer when all the gates are together for obvious reasons

Cramped, crowded aircraft. Poorly organized boarding. Tasteless crackers to eat. 40 minutes late. A standard US air travel experience.

Would not mind having movie options an available like Delta, but is not necessary. Did not have food, so cannot appropriately rate that section.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

Staff was far less than helpful at all times. Departure and arrival times mean nothing to Southwest. Extremely disappointed, will never fly with them again, and I’ll be sure to share my experience with all.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

The seats were a bit cramped and worn, but otherwise okay.

I would have liked to arrive on time - not 5 hours late!

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

Flight was great. Efficient boarding. Short flight. Early arrival. Friendly flight crew. The entertainment system did not work well. Could not access it until the aircraft reached 10K feet or more. Lots of glitches.

get E+, a must for 5 hours flight if you are tall

The first flight was better in terms of the aircraft.

we were delayed going into and out of Newark Airport by 3-4 hours each way. Excuses/reasons given were misleading. Weather was cited at first when there was NO weather issue. Turns out Newark had a shortage of staff and runway construction. United knew this and should have NOT scheduled flights when they know we would be delayed so long. I will avoid United and EWR airport at all cost going forward. Delta never looked so good.

A bit rush for transit. Food and entertainment are not available

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Eventless. It was a good flight and good crew. Can’t complaint.

At the beginning of the flight there was some turbulence and the announcement was made that there would be no beverage service. The turbulence only last about 5 minutes then it was smooth sailing. I noticed that first class got their service, but the rest of us did not.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

It was nobody’s fault - but the plane came 4-hrs late and we were updated randomly in 20-30 mins increments which left us hostage to sit and wait expectantly. It was very long and got very late. Our plane didn’t land until nearly 1 am! Also the toilet wasn’t working. The hosts were nice enough but were clearly “about to pass out” as one told me. Lastly, there was no snack or even time for it. Just a bad experience overall.

In flight connectivity (via T-Mobile) was often not working.

Pitch was very small. Knees were on the seat back in front of me.

Several delays. Next flight was worse. Did not arrive home until 2am PT
