Airline reviews

One, we were met with more than six hours of delays with no information flowing from the airline to the passenger. I had to continually refresh for updates to departure time - which changed multiple times throughout the day. Updates were never pushed to me nor was an explanation provided for the delay until this morning. Two, while they claim that "due to the short flight" no beverage service would be provided. Our flight was mostly empty. I'd think given the massive inconvenience, SW could have shared a Diet Coke and some peanuts. And BTW, SW used to always make these available on this flight back in the day. Let's be honest, this is cost savings at the customer's expense.

I like the staff members they were super nice and helpful very sweet people :)

Unfortunately, I left my headphone's case in the bag of the front seat. I was seating on 9C. Hopefully the found it and I can get it back. I have not been able to get in contact with Southwest. Other than that, everything went fine.

It's a shame that SW was previously my preferred carrier until they started imposing all these fees (luggage, seats,etc) and pulling back on other perks. I only flew with them this time due to time frame I needed to be at destination. Wasn't provided gate info during check-in, Gate info wasn't displayed at airport until last minute, gate info didn't match what SW personnel announced at fate. Kind of a mess.

Delayed and once landed waited very long for the luggage

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

It was good. I wish you had gluten free snacks for my husband.

Great quik boarding, friendly gate agent and crew. Let early

The wifi was barely operable. just enough to charge me, not enough to be useful. I wasted 2 hours of time I could have been working. So now, I' have two hours of work this weekend to catch up on thanks to Delta's crappy technology. Plus I'm out the money!

It’s a 3 hour flight with no entertainment and no WiFi due to Delta using old planes on this route and food is cold. Today we were told no potable water on the flight to even make coffee or tea. Ridiculous service in this direct route for business travelers and non business travelers

Audio Visual Equipment lacking content and features. No connection ability for noise cancellation pods

All good except the dining. Both meals were the worst I’ve ever encountered on any previous flight.

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Nothing, it was a fraudulent transaction. You probably should have caught that.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Flight was delayed due to maintenance issue. Missed my connecting flight. Got rebooked in a middle seat when I had a first class ticket.

First no airplane at the gate because the previous flight was canceled (and they didn't know?) Then we board and there's a maintenance issue. Then we're told the technician doesnt have the right certification and they need to call another. Then FINALLY we are taxiing. But wait! Flight plans expire after 3 hours and we were not granted permission to take off. So taxi was halted while a new flight plan was filed. Then....no beverage service. Never flying American Airlines again. If they mess up operations this much, how good can their maintenance or training possibly be?

There is was everything terrible all my flights was delayed so I missed my connection flights

Unfortunately the flight was delayed by almost 2 hours, so I missed an appointment arriving into DFW

Comfy and timely flight thanks to Cathay to all crew and the captain for our smooth landing.. above all thank You Lord for our Safe flight ❤️🙌🙏🏽

I love having an opportunity to choose different the dietary restriction. Crew was very nice. I was watching movies & TV shows entire flight.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Got home at 3am after deboarding the plane. No compensation offered by American

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Terrible. Delayed my family flight for several hours affecting family plans

Flight was delayed and then my second leg was completely canceled. Had to get a refund

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

My flight was canceled I was promised a reginf still not received.

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

It was a short flight so no food or entertainment….

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

I like the easy check-in and boarding process. I love the non stop flight
