ReginaFlew with GOLMIA-SEAJun 2025
It is a good connection, it gives you enough time to go through passport control and luggage claim and drop off. Eat close to the boarding gate because the next flight lasts 6 hours and there is no food service on the plane.
FrankFlew with Spirit AirlinesMIA-EWRJan 2025
Don’t get to the airport to early. The boarding is orderly so you don’t have to be there too soon

New York JFK is massive and the signage there for connecting flights is not so good as you need to travel via AirTrain between the different terminals and the signage for this is missing in some places, making it confusing as to which way to go.

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Flight was an hour late, who knows why. It was OK, nothing outstanding.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Flight left early and arrived early. the whole trip was excellent.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

Staff members were not helpful they ignored all calls for an attendant.

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

Internet was a bit expensive and did not work ask that week otherwise a good flight

Food was ok, but not as good as I have had before on AA.

Pretty good. The food was just mediocre, the boarding and crew were good.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Crew professional. Easy bag drop off. On time. Good entertainment.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

The flight was delayed twice with minimal explanation. The terminal and airplane were filthy. The food voucher didn’t even cover a tiny pizza from a kiosk in the terminal. All in all, a pretty miserable experience for a flight to attend a funeral

I will use spirit more New clean aircraft Excellent crew ! Quick boarding process !

The flight was delayed be over 3 hours. I tried to get a refund for Vivian Kirby and my session kept being stopped. I was NEVER able to finish the prosses...after 2 hours of attempting.

For the minimalist experience, it is really a great ride-- feels a little like public transport i guess

I didn’t mind being delayed due to weather, but continuing to post (and not update) that we would be delayed until after the flight was already supposed to have taken off was a bit much. In the future, please announce the delay even if the time is still unknown.

This gate agents are always so rude! I stopped flirting with spirit years ago for that reason I thought it would change by now. It’s so tacky they try to treat you like a school child i hate it

The flight and boarding process was smooth. Wifi was unavailable and I prepaid for it. Have requested a refund

Spirit is a very uncomfortable travel experience. It’s cheap but you are squeezed into the seats like canned meat.

Friendly employees, good seat, on time, Great flight. Pilot and attendants greeted passengers as we deplaned. However, I could not ever understand what the flight attendant was saying on the mic. It was too fast, and too loud.

The flight was delayed four and half hours for paperwork on a maintenance issue. Very frustrating.

The experience was good. No frills but I got there safe and sound and on time.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.
