Boarding was tough as we had to take a bus out to the plane and walk up a lot of stairs. Difficult with heavy carry-ons that said I got an entire empty row of seats, which was excellent for an international flight. Food was very mediocre but happy with the comfort so not complaining.

Boarding was tough as we had to take a bus out to the plane and walk up a lot of stairs. Difficult with heavy carry-ons that said I got an entire empty row of seats, which was excellent for an international flight. Food was very mediocre but happy with the comfort so not complaining.

After I checked in, I realized we had no seat assignment. It said they would be assigned at the gate. This was really frustrating because I usually use a lounge before flights, but I couldn't because I had to be at the gate to ensure we got our seat assignments. The gate agent arrived an hour before the flight left. I was the first one up to ask about seat assignments. She told us to wait for names to be called. Dozens of other passengers were paged, but we were not. Finally, I asked my husband to ask. He went up and was also told to wait. About 10 minutes later, they called for boarding. We still had not been told our seats. We went back to the desk and they were in a panic, saying we actually weren't on that flight. Then they made an announcement telling the stand by passengers to not board (in case we needed their seats). It was so stressful and unprofessional. Finally they gave us our seats. I have no idea what happened and why the two desk agents seemed to have conflicting ideas about our seats, whether we were on that flight etc.

Subject: Complaint Regarding Disrespectful Behavior by Delta Air Lines Staff at Boarding Gate Dear Delta Air Lines Team, I am writing to formally file a complaint regarding the behavior of a staff member at the boarding gate today, May 14, 2025, at Las Américas International Airport. While we were preparing to board flight DL-1829 to New York, scheduled for 2:28 PM at gate T-11, we were informed that the aircraft was experiencing water system issues and that passengers were advised to use the restroom before boarding. I politely approached one of the Delta staff members to ask whether the lavatory would be partially or completely unavailable during the flight, as I am traveling with a baby in my arms. The employee’s response was extremely rude and arrogant. He replied, in an unnecessarily hostile tone, something along the lines of: “It’s either that or we cancel the flight — do you want us to cancel the flight?” This response lacked any empathy or professionalism. I understand that technical issues can arise, but that does not excuse such inappropriate treatment of passengers. I felt deeply disrespected and disappointed by the interaction. I sincerely hope appropriate measures are taken, and that all staff members receive the necessary training to treat passengers with courtesy, especially in delicate situations like this one.

This is speaking of the original flight leaving on April 30th(DL 1957) not the rebooked the following morning DL 9887. On April 30th, it was unusually crowded at Sangster International Airport (MBJ) the morning my mother and I arrived for our flight. She had to exceedingly long time for a wheelchair, once a wheelchair attendant arrived to take us to thru immigration and security then to go to gate the flight was boarding. We stayed on board for 3 1/2 hrs until the flight crew notified the passengers that flight indefinitely delayed so we had to stay by gate area. Before that my mom had to wait an additional 20-30 mins to deboard the plane. Was given food vouchers, by the time I came back the gate agents said the flight was gonna to reboard, so all the wheelchair passengers lined up. We waited an additional 45 mins, while I received a notification from kayak that the flight was cancelled. And on my delta app updated that flight was being detoured to Miami then from Miami back to JFK. We boarded the plane started to eat, then the flight crew notified us the flight was indeed being detoured & that how come the gate agents didn’t notified the passengers. We stayed on board for another 30-40 mins then was told by the captain that they tried all avenues to get the passengers back to JFK but the crew couldn’t continue the journey and the flight was cancelled. So we deboarded the plane again. Was told that we were going to be setup in hotels for the night. The hotel that we setup to go to wasn’t suitable for my mother’s needs and requested one nearby we were located in Jamaica. So any we had called a taxi to come to take us back where we stayed in Jamaica, that we had to pay out of own pockets.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

third trip overseas with delta recently where the TV did not work- not acceptable for a 8 hour flight! your food really has declined crew great and I am loyal to delta

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Everything was ok!! Just bags came up a little be late.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was On time and landed 30 mins early considering we were flying into Newark. No complaints.

get E+, a must for 5 hours flight if you are tall

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

Multiple delays and not straight answer from the United team

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

The gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

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.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

Newark airport grounded inbound flight and only announced when the flight was about to start taxing.

The flight was two hours late to take off. The captain kept making announcements in English, but the volume on the speakers was low and we could not hear him. The flight attendant’s French translation was loud and clear, but we couldn’t understand French. The crew was nowhere to be found to relay what the captain was announcing. Very frustrating experience. American has to do better.

Paid $35 and not able to access the internet at all.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

You ant watch TV if you don't have a device, the seats have more space, and the snacks are different.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

The flight was canceled and was bounced around time wise with my elderly parents. That being said the gentleman in custody service was amazingly helpful

It amaze me how other airlines leave on time and Spirit always have some type of delay. I’ve flown with Spirit many times, but it reached a point I’d rather pay twice the amount and not deal with this corporation they never do nothing to reimburse people for their time or headaches.

Too many time late and postponed No electrical power for my electric devices

Flight and crew were good, no complaints at all. Easy, uneventful, quick flight. The delays, cancelled flight, hold time to wait for customer service on the phone were not good. One person that answered told me the delays, first on the way to Newark, and again on way from Newark were due to weather (there was no weather on flight coming in); turns out that was not true. Multiple flights were delayed and cancelled that weekend- 6 for the trip leaving on Sunday from what customer service at the desk told me. Newark was having issues with air traffic controller I believe. So, getting false information and only options of rebook (for another day, or one with stops to get in the next day), refund or a credit valid for 5 years, did nothing to help me get to work the next day or get my son home for school that next day. There was no sort of compensation for the wait or cancellation from airline or from airport. Just out of pocket for the uber ride and the missed hours at work.

The seats! Do not nickel and dime! Be transparent about all your fees!

It was fine, Can’t blame you about airport issues.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

We had an 8 hr delay so it was not good

The reservation was cancelled after a day and a half due to family reasons. There was no flight from Newark to Orlando 03.01.2025. Very bad customer service. Never use again.

Overall good experience for the price. Thank you for making travel affordable.
