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!

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

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Seats were really tight and the seat belts did not give enough slack.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

The WiFi has been awful on my last few Delta Air Lines flights.

Only one side of the heafphone jack work. Crew was friendly and helpful.

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

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

leg space better than expected. two washrooms for one plane isn't enough.

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

Maybe add a seat trade app for flyers that didn’t get seats together

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

I was forced to check my carry-on backpack despite there being space - but it came out on the baggage carousel so fast it didn't even delay my pickup. Otherwise a good flight. Boarding began early (which was disadvantageous for me) but fine.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

Flight cancelled. Added a day and a half to my travel. American Airlines DID put me in a hotel for two nights, but have not given any money back for any of this! I spent money on an apartment at my destination that I basically wasted because I could not arrive.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

The plane was very warm and the crew turned on the lights for the entire snack service.

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

My experience was okay. The flight did not offer even water without a fee. Also had to pay extra for my carry on, as I was told I had to check my bag, even though it said I had the option to carry on a bag when booking. This costed me an extra $100. Would likely not fly with Spirit again.

Seats were comfortable but dont recline at all. Checkin online was easy but didnt provide a gate until last minute. Flight attendants were very unkind, not friendly and didnt go over safety procedures in case of a crash. No free snacks or beverages, not even water.

The booking was cancelled the next day. Spirit Airlines refunded Kayak cheapflay the full amount, but I was only refunded half. Costumer service is disgusting. Be careful. You can lose your money.

Spirit airlines was extremely uncomfortable. The seats were hard.. the constant up selling (from lack of food or even water to $15 for wi fi ) was annoying. Not a recommended airlines

Our experience was not a good one. Our flight got cancelled and was not given any accommodations due to the inconvenience. We lost time on our vacation due to this inconvenience

They are very particular about size of the bag. Mine is small bag and has wheels. Bag wheel edges are bit outside of the measurements bucket. They charged $99 as carryon bagage

The plane flew smoothly and the crew was polite and kind. We loved our flight!

The senior flight attendant was engaging, funny and made everyone feel at ease. She is an asset to your team.

Terrible-extreme delay with very little communication, plane was overfull, luggage was returned on baggage claim in filthy condition.
