It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.

Southwest was greaat! The most expensive but the least upsetting for those we were flying to see.

Boarding was easy. The seats are small and fairly uncomfortable

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Absolutely horrible. Flight was delayed 4 hours and they had no clue what was going on.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays

Flight cancelled 2 hours prior to boarding. No explanation. No refunds.

Delayed by 1.5 hours. Terrible apologies, half hearted at best. It will be a LONG time until i book w Jet Blue again. Very disappointed.

My check in was stressful. I somehow lost my seat from my original booking, the plane showed no availability/no seat when it was time to check-in. I called and was instructed to try to get a seat at the airport. I asked if it was a full flight and the travel agent said the site showed some seating but was not able to secure one for me. Why not? On my way to the airport the app finally revealed one available seat towards the back of the aircraft that I was able to book. It ended up being an overbooked flight, so glad I wasn't stuck.

Flights with JetBlue from San Diego to Boston are a miserable experience. The flight was delayed about 1.5 hours due to “weather” supposedly but the flights for other airlines left on time so it just have been some kind of weather that only affects JetBlue. I had a small carry on - purse. The crew stored it in a bin 2 rows down from me because they were using the bin next to my seat for other people’s stuff. The TV screen in the emergency row seats does not work. It just was awful from start to finish. When we landed, we had to sit inside the plane for a very long time because the plane had to be moved to a different gate.

They made me check my bag and I didn't need to as there was overhead space available. I paid for a seat towards the front of the plane and it didn't recline. I requested a refund and they declined to give me one.

I have to congratulate Kayak (and Dylan the Chatdeal agent) because because when we decided extended our trip in Florida by two days, there were many direct flights oprions back to Boston available on the Friday we wanted to fly on the JetBlue website, but once I canceled the original JetBlue flight on their website, those direct return options disappeared immediatley! I think it's a game JetBlue plays. . Luckily, I checked Kayak and they had a direct flight that wasn't appearing on JetBlue's website and so I booked it, and we were able to fly home direct through the Kayak booking when JetBlue was offering nothing (even though I have been a True Blue member for 20 years, and also am a Mosaic member). So much for loyalty- their algorithm for booking is like a shell game. JetBlue used to be a good company but now they're worse than anyone. Also I was originally booked this trip to Florida, two months before the departure date, I booked the trip on JetBlue's website and then after the payment part, they said there was a problem and that I needed to do the booking again, so when I immediately went to rebook , the price had gone up 30%! I called them and it sounded like they had heard this so many times before and the guy told me to check back in 10 minutes and the price would be back to where it was when I was booking- it but it never was. How could the price go up 30% in one minute two months before the flight???? They're playing a game with their customers. Anyways, I booked a cheaper flight then at a less convenient time. So fast forward two months the night before the 7 AM flight, they sent me an email at midnight when I was sleeping to let me know that my flight at 7 AM had been canceled. The only thing they offered was a flight that night from from a different airport (Providence) to a different airport in Florida (West Palm Beach) or a flight two days later. No compensation, nothing. They couldn't of tried to get another plane to the Boston airport? They had all night to do it. I passed on their ridiculous options and flew with Delta and it was a great experience. Of course, I had to pay a lot more booking on the same day, but JetBlue doesn't care. I put in a lengthy complaint with the agent who assured me someone would get back to me by email within three days and I haven't heard a thing. JetBlue used to be a good company but now they're among the worst. The only thing they still have is decent legroom, but the corporate bean counters will probably start taking that away too.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

Great experience. Good dinner and service. FA's were very nice and attentive.

Mostly good. The WiFi wasn’t working so that was not great.

I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

The flight was fine, once we got underway. It was more than hour delayed

Arrived 40 min early which was great - sat in runway for 35 min so no gain. Then waited for luggage 45 min. They need to staff accordingly knowing its one of the busiest week in Phx

My flight got rerouted due to crew rest. I was sent to Dallas customer service was not very polite. Was given a $40 room voucher for Motel 6 and $12 to eat with. It delayed me by a day. Where if I would have just stuck with my original flight Arizona was delayed to Cleveland and I could have made it home. They put me on a 9:00 flight out of Dallas to Cleveland without my knowledge or consent. When originally I was told it would be 8:45 a.m. on February 1st. I told them I could not take the 9:00 flight because I did not have anybody to pick me up from the airport at that time. I'm extremely disappointed in how I was treated. And I will not fly American Airlines again.

It would be nice to have some low carb options in the snacks.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

Remind customers of the need to have passport or new ID for boarding.

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

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.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

This airline sucks. They offer low rates then charge you for everything, the app does not work well, the seats are the most uncomfortable. Maintenance issues on the flight, and you still have to sit through their credit card commercials. People are nice enough but does not make up for overall poor experience.

Flight was delayed one hour. Notification to the crowd waiting near the gate was terrible…announcements were unclear and very hard to hear and therefore understand. Frontier does NOT send texts to notify, only email. The reader board over the gate itself was NEVER updated to indicate the gate had been changed. It’s like a bunch of children are running things.

We’ve all seen the YouTube vids of out of control passengers. But this was an instance of a highly aggressive, bully flight attendant. Yelling in the face of a vet with PTSD who was texting their family. And no , we had not yet been instructed to put our phones in airplane mode. My suggestion is that you should pay whatever difference there is in order to avoid Frontier airlines. Additionally, after 3hrs trying to get customer service frontier offered a $25 voucher. I declined. This experience was so traumatic. To be verbally assaulted and abused by a flight attendant that has the power to say “boo” and I miss my flight ( which was to a family member’s funeral ). Frontier is unsafe and I cannot impress enough how much I discourage anyone ( esp those with any kind of disability like PTSD ) flying on Frontier.
