Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

It was a crowded flight. They did the best they could.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Horrible. First delta flight was delayed. I ran to my connecting flight and arrived to the gate 13 mins before departure. I told the gate agent “I’m here”, she told me flight was closed while giving my already confirmed seat to an stand by passenger. I said again “madam, I’m here with my confirmed seat” and she said “no you’re not here@ and gave two stand by people a boarding pass and let them board. I asked “madam, why do you do that?”, and she repeated “you’re not here”. That was very rude. I’m disappointed of delta. It used to have a good customer service. Things have changed, but not for good.

full flihgt but crew and passengers all helped eachother we landed early! however we then had to wait 40 minutes on the tarmac to get into the gate there were people trying get connecting flights, assume its an airport issue but still frustrating

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

Do not get fooled by the term “Delta One” flat bed! The seats were super narrow. The ottoman for the feet was so narrow that when you recline the seat in flat bed position, you can only fit one foot in the 8” width space. There was only 1 flight attendant for First Class. The breakfast took 2 hours to get served. Instead of offering French Toast, the served bread pudding. The champagne with orange juice or Mimosa tasted terrible. Almost all the movies offered were ridiculously old. For a long flight from San Francisco to NY, it was frustrating! I DO NOT RECOMMEND this flight!!!

Really big guy next to me Attendants moved him to an open row

the entertainment for the flight from DAL-LGA was not available.

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Everything was good except for deplaning in NY. Took way too long!!

Jet Blue keeps getting iit wrong. 4 hour mechanical delay followed by terrible boarding experience. This is my third horrific jet blue flight in 2024. I am going to try to avoid this loser in the sky

no wifi and the aircraft was very old with tiny 4” screens.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

Flawless trip. Pilot came out and introduced himself, welcomed everyone, made a light joke to put everyone at ease. Arrived quite early.

JetBlue's check-in was great, but there was an in-flight flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'No, bathrooms are locked! Go back to your seat!' The flight was more than an hour delay, which made me almost miss my connecting flight. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them so long to get a hold of maintenance and for maintenance to get started. Most importantly, my 3 checked baggages are missing! I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all missing!

Safe takeoff and landing Better snacks and coffee. Headphones for the TV monitors.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

We waited to takeoff for about 1 hour delay for a 20 min flight.

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

the head jack on my seat didn't work and the power outlet didn't work for my seat

That flight was smooth, and staff we courteous. it was a full flight so very tight. The boarding through security was not properly controlled. it was rushed and the scanning process for our bags, etc. was pilling up at the other end with no time to empty our belonging my personal items almost toppled over on the floor if i hadn't caught it rapidly. Was it just that time, or always like this - cant say. other than that all else was fine.

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

I liked that we arrived earlier, you could improve your snacks give away

We learned certain countries (a few) require a notarized letter from an ex to give permission for children to travel to those countries with the other spouse together with birth certificates. To find this out one hour before flying—not good. Nowhere is it documented by the airlines though they require it. Make sure about all documentation required.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Comfort of seats, ease of boarding. Food selection could be better

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

One of the worst flights I have ever taken Delayed over an hour without communication from the crew; very scary Entertainment not working Crew NASTY cabin cold

May never fly American again Delay in take off WITHOUT EXPLANATION Cabin freezing Crew NASTY entertainment did not work entire flight

It was wonderful upgrading to first. Plane was so cold thou. Crew was great. Wish there was a food option in first for such a long flight. Doesnt matter the time of day. Chintzy.

The flight was so short that the lack of leg room didn't bother me for long. The plane was smaller so only two seats per row and there were chargers. However, they didn't serve any snacks.

Horrible trip. I won't fly AA again Boarding was a nightmare because they squeezed people into the waiting like sardines. My connection was 30 minutes and the run to the gate was horrible. Then the flight was canceled AFTER boarding. The Flight attendants did not know what to do and gave out the wrong instructions. They finally sent us to a different gate. Again, the waiting was like a sardine tin. The flight was okay and my baggage arrived fine.

Over an hour delay in departure but I was notified beforehand. Another delay on tarmac upon arrival at LGA. We ended up departing the plane almost 2 hours later than expected

Frontier is a crappy airline nothing about it is honest

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

Terrible. Seats are bad and the baggage policy is inconsistent

Better than I expected but I did pay for a seat and carry on bags ahead of time.

I hope to avoid flying with them in the future. First flight got cancelled then got stuck with a 13 hour layover in Denver. The process was long and frustrating to many people.
