I've taken four flights with Southwest within the last three months and every single flight was delayed.

I've taken four flights with Southwest within the last three months and every single flight was delayed.

I liked the new boarding process. I thought the buyup options (legroom, early boarding) to be easy to request and reasonably priced. All the Southwest team from gate to in-flight were so nice.

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

We had a 5 hour delay on the tarmac in Baltimore

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

It went well. Plane wasn't full. Will be great when assigned seating is in place

As always it was a pleasure to fly on southwest.

Excellent! There was a delay due to the weather and they did all they could do to keep us comfortable & updated. Thank you!

Couldn't connect to the internet and movies. Needed help.

Wi-fi was out for the whole flight. I pay a premium to fly Delta because it has wifi and because it was out I didn’t get to work on anything I wanted to. I’ll have to make it up later this week by spending less time with my family.

I just wish the boarding process/time to take off after boarding was quicker and more efficient. I also wish that the overhead luggage was managed better. almost every time i fly there is no space for carry ons and they are either checked or I end up having to store it several rows back from my seat. Delta should not offer carryons for all customers if there is not actually space for everyone

Flight was fine, it was on-time and was not cancelled which is very good. However the small cabin bag was forced check-in although once I entered into the flight there was lot of space which would have accomodated 10 such bags. Moreover this caused delay on arrival of my bag due to which I missed my booked cab and had to wait for another 20 minutes before the next taxi (Uber) arrived.

Only flew a short distance from Buffalo to New York City JFK SO it was okay

Delta seems to be getting worse. They are trying to take any comfort away from poorer people to make more money selling it to the rich. I paid for delta comfort and on my flight from Rome to jfk I had a tv that would go on and off automatically and literally no electrical outlets or usbs worked which was advertised in the price of the fare. The infotainment system wasn’t fully working. Luckily the movies worked and the plane was needing a lot of repairs. The jfk to Tampa flight they stuck me next to this really larger guy who was half in my seat and they should have made other accommodations for him because now you’re interfering with the fare class I paid for and act like I shouldn’t care because I didn’t pay for first class. I couldn’t even pull out my tray table because of this guy. The safety video tv screen you couldn’t even see it. It made me a little scared to fly delta anymore, because if these planes are this much in need of servicing, I have to wonder if the plane is going to make it to the destination.

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

Cancelled my flight. Left me in airport for 12 hours. Rude gate attendants. Worst delta experience I’ve had. I hope they have a focus group and return to thinking about customer service.

an he late. super rude gate agent, to every person. spoke down at people.

It was good. The leg room was not great in Row 1.

Crew handling the boarding at the gates are quite aggressive with the passengers and must be given training/ refreshing courses to improve customer experience.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

Mostly good, flight take off in time and land earlier I can’t ask for more..

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Uncomfortable seat. No help for my disability. Staff refused to help me put my carry-on in the overhead bin. So I had to check the bag.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

The delays were not communicated well at all. I was in the airport for over 9 hours with little knowledge of if I was actually going to reach my destination.

It was OK, but it was delayed about an hour, and my luggage didn't arrive till about an hour and a half after the flight

Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.

Our trip to Spain turned into a stressful ordeal with cockpit issues and FAA air traffic disruptions. Our American Airlines flight from Raleigh to JFK was delayed nearly four hours, causing us to miss our connections to Madrid and Jerez. We were left stranded in New York with children, even running out of diapers while trying to sort everything out. American refused to cover hotels or rental cars, leaving us to arrange and pay for them ourselves. The delays also disrupted our prepaid rental car reservations in Spain. It was a frustrating and expensive start to a family trip we had spent months planning.

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

Very cold on board it was like having 16hours sitting in a fridge

My experience was excellent for a business trip. I like the smaller jets because everyone gets either a window or aisle seat and the boarding and de-planing goes much faster. I really like the schedule American Airlines has between Atlanta and NY - lots of options. Crews are great and very accommodating. Sometimes the flights are not full and they let people move around once the boarding doors are shut to spread out.

Primary flight attendant in FC wasn't that engaged throughout the flight. All other aspects of flight were good.

On time departure & early arrival. Made a long day much better.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

Frontier is good until they cancel your flight. Way too many cancellations.

Flight was delayed but it was very smooth. Crew was very nice. Seats are uncomfortable but ok.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

The worst. They don’t follow procedure for boarding per group. Flight got delayed for no understandably reasons, they changed our destination from PR to Miami, left us inside a plane for more than 8 hours, then cancelled flight in Miami leaving us stranded. Poorly managed re-accommodation for a new flight and overnight stay so I have to spend in a new ticket and my own hotel room to been able to get to my office next day. Lost 2 days of work and as a doctor, patients loosing their appointments. to other flights and besides

I was 2 hr arrive in the airport and 45 min in the line . After take to my turn . The agent tell me I’m later . I can not board . So my vacation was going to the floor . Just for their bad customer service agent in the airline

Since they are a budget airline, I wasn’t expecting too much but they did some things well. They were on time, the plane was clean, boarding was fairly straightforward and the staff was cheerful and friendly. The only downside was comfort. The seats were fairly hard and after a 2 hour flight your rear end is not feeling so great. Maybe a little more cushion in the seats, Frontier!

The flight left over two hours late. They charged me $180 to bring a carry on. There was an error with the spelling of my name and Frontair agent lied that I would need to pay $200 for her to fix the spelling, and pressured me that if I don't do it quick I would lose the flight. I called back and another agent said it costs $75 to fix. All in all, this company is a complete scam.

I took my first and last flight with FRONTIER. The seats are not able to be reclined so it’s not a very comfortable experience when you take a flight of 3 hours or longer. You must pay for your luggage either carry on or check in, so taking all this in consideration at the end what you think you’re saving your paying in services that should be included. Not a beverage in sight. . You’re seriously better off getting on a proper airline such as Delta, AA, United, etc.

Crew was excellent. Plane was small cramped Airbus A320. Seats were narrow.

Be prepared for crowds and chaos upon arrival at the Orlando airport
