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.

One of the best airlines for fast boarding, on time arrivals, and top notch service!

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.

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

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

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.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

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

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.

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

Delta flight overall it was goodT!the crew could do more and the food could be better.

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

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

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 great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.

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.

The Mario was so helpful and provided amazing customer service however l have being waiting for a callback for almost a week now and have not heard anything further after l informed them l wanted to change my date of traveling because of my hospital appointment even send them proof and l was unable to use manag your booking on their website is a bit frustrating and l would appreciate an update on My request as soon as possible. And have called them times without numbers no response

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

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

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.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Delayed 6 times. Eventually rebooked and missed a whole day of my vacation. Hot mess

Unfriendly gate staff and significant delay once we were on the plane.

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

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.

No fault of Frontier staff: plane was very late, reached Orlando at 1 am, took a while to get luggage. Weather, gov financial shutdown impact on TSA, air controllers seemed to have multiple flights backed up. Frontier staff seemed to cope as gracefully as possible. It did reassure me that I and my new hip could adapt to travel challenges. Food/entertainment were irrelevant to my trip.

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

Everything was on time and smoothly run. All employees appeared happy and enjoying their job. The delay in take-off was unrelated to anything in Frontier’s control. I wish there were a caffeine-fee, sugar free soda drink option besides water. There are multiple zero sugar caffeine free options.
