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.

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.

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

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

We flew early evening on New Year's Eve. Our plane was less than half full... Great for the passenger experience -- not so much for the airline lol. Comfortable, spacious, smooth flight -- and early arrival!

The crew was horrible. Cleo was the most unwelcoming flight attendant I’ve ever had.

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!!!

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.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

There was a group of school age passengers that were very loud and unruly with their chaperones were no where to be found.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

The leg space between me and the seat in front of me was excellent.

Not being able to purchase my check in baggage online was a negative.

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

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.

We liked quick boarding and on time departure. Seats were very uncomfortable.

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.

Frontier is a crappy airline nothing about it is honest

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

I paid for extra leg room. The flimsy plastic seat underneath the floatation seat did not line up with the arm rests. It seemed as if the plastic part was zip tied on but immovable. This caused severe uncomfortable for the duration of the flight.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

First time flying with Frontier . From buying tickets ,getting boarding pass and boarding plane was super easy. Definitely would fly again with Frontier .

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

they charge too much when you arrive in the air port
