Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Good and consistent Printer in lounge did not work for me :(

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

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

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

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.

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

The first flight was better in terms of the aircraft.

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

The gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They delayed our flight by 45 minutes and then re-updated the departure time back to normal schedule with no notification, email, or app update causing probably 40 people to miss the flight as they left without us.

Cramped seats. FAA should make airlines have more legroom, for even short people complain

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?
