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.

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.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Very good. Sad to learn Southwest is going start to charge for bags

Our flight was diverted from being a non-stop to getting within 150 miles and requiring another plane. We heard 4 or 5 different versions from SW as to why we had to stop, then wait for a replacement plane. Five hour delay, weather did not come up as a single excuse.... communication was not clear and well explained. No one really took charge!

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.

WiFi on the flight was not working. Thus, entertainment options were limited.

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

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

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.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Coach seating is debilitating, neither my husband or I can walk the following day

Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

The airplanes were so old and out-dated it was terrifying to fly on them.

It was very good. Our flight was delayed and we as a result missed our connecting flight but rescheduled to the next day. The Need Help staff was so great and offered us compensation that was beyond satisfactory.

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

Love delta but the delays and long waits for updates was just too much this time.

Flight was 3 hours late so only had an OK experience

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 ;)

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Crew professional. Easy bag drop off. On time. Good entertainment.

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

Good experience but the snacks are not gluten free, so I cannot eat them.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

I was a little disappointed of not having an android charger. Only one it was for an iPhone. I've flown American in the past and had access to one.

They switched my flight to Spirit, Never using Kayak again,

i was denied boarding, even though i had an assigned seat, checked in on line and was at airport early. Then they refused to fully refund the the fair and replacement fair because they claimed it was "no show/denied boarding". I will never fly this airline again

I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.

This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

It was a no frills flight. Would have liked to be able to charge my device

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

Everything went as planned. Crew was great. Seats were still not that comfortable.
