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.

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.

One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

The seat was not comfortable. 1D. My back was sore all night and the next day.

Terrible all around. Left prior review detailing massive delay/cancellation to then rebook travel. Topping on the cake was lost luggage even after travel to ultimate destination was secured on a new plane(s).

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.

Never went on board this flight. Kayak uses Underpricer (which is a scam business) as it's "customer service provider". This customer service is a classic bait and switch "service". I Got caught in the UnderPricer Bait and switch scam. 14 hours on the phone with people from India with heavy accents and upselling me to useless products. The original sell was a flight on spirit. Then they contact me later, an say after they have my money that the flight is no good as is is only one seat for a party of two. I am still in dispute to get my money back. Went to Spirit direct and had a beautiful vacation. I should never have used Kayak and their rip off artists UnderPricer.

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

I like everything about Southwest. From customer service to crew and prices. I travel a lot during the year and Southwest is the best!!

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

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

Great crew, flight on time, luggage pick up a breeze

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

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

More extra space was awesome. Even though I was on the first groups to board, bin compartments were already occupied by passengers seated on other seat numbers. That is unacceptable.

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

The flight was excellent, I recommend people to fly with Delta

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

When we enter the airplane there were many water drops falling from the ceiling all the way long to the seat , and when it departs were even more over us getting the hair wet , and later on was too hot , the A/C not work well.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

This planes staff was top tier. Everything went great and had a great flight home.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

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

IT WAS A LONG TIME SINCE THE LAST TIME I TRAVELED. I THOUGHT I WAS TO BE LOST BUT EVERYONE WAS PRETTY NICE WITH ME AND MADE MY EXPERIENCE NICE. THANKS

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

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

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

AA was a very good experience. The employees are wonderful

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.

We had a very pleasant flight with very comfortable seats and nice staff.

Seats in coach aren't padded enough for a 6 hour flight

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

the handling of my luggage. It was Lost or stolen At my destination.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that

Uncomfortable seats at row 40 A and 40 C, they didn’t recline. Also, my prior seat selection was not honored.

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

Good- no snacks on a 4+ hour flight is painful but more painful was the lack of WiFi.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

Was left with many other passengers in SJU by frontier airlines due to delay caused by frontier. Worst experience ever and worst airline ever.

It was horrible. My plane was delayed until the next day resulting in me losing a day of work. It’s absolutely unacceptable and I won’t be flying with you any more and I will strongly caution others to avoid your airline as well.

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.

When we arrived we lasted 48 minutes to be able to get off the plane without air and the plane turned off more than half of the passengers because after they started to leave they realized that the bridge was defective

Pro: The stuff was great. Friendly, patient and caring. Our seat row was clean. The bath room was clean. Our flights were close to on time. Con: The leg room is too small. No blankets or pillows. No entertainment devices at all. I can’t remember to have a food choice. I would fly again with frontier for short distances.

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