Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

We sat on the plane on the tarmac for 4 hours.
I'm not a fan of Southwest's model. I don't like the herding style of boarding.
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
Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗
5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.
Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!
Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market
It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane
My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.
The entertainment and wifi mostly didn't work on this flight.
Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.
The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.
I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us
I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog
Excellent service despite turbulence during the flight. Flight attendants were remarkable!
Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.
Food choices were very limited. Taste of the dishes was average.
I liked all the informational texts. I always knew where to go and when .
Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.
The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.
It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.
The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.
The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.
Communication since no reason or explanation was given for 3 hrs delay
Flight was delayed several 3 hours - no reason was given and no communication what so ever.
No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.
Excellent from start to finish. All staff members were amazing!
Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.
Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.
It was too hot in the cabin. The AC did not help.
Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.
Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking
It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable
I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.
Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.
The plane failed preflight inspection, so we sat there for 90 mins while they tried to fix it. Ultimately, everything was remedied and we made our connecting flight; instead of a 2 hour layover at the airport, we spent it waiting on the plane.
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.
Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?
Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.
Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.
Stuck in Phoenix for two days, not even a hotel voucher offered.
Every day about it was very different all the boarding pass where all wrong l miss flight no refund all crazy
