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.

The crew was amazing; Von, Vera and Guadalupe were very friendly and attentive throughout the entire flight. They were friendly and welcoming to everyone. A solid and dedicated team for sure!

Terrible. I was bumped off of my original flight and spent the next six days fighting to get back on it. I lost hours of my vacation trying to get this situation corrected.

Our flight was canceled after several delays. No hotel vouchers offered, minimal help for resolution leave me ultimately to cancel and book on an other airline. Then waited to get bags for more than 3 hours This whole experience has been awful!!!

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

I like for how they process during check in. It was very smoothly.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

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.

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.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

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.

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

Multiple delays and not straight answer from the United team

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 ;)

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

Flight was cancelled 3 hrs AFTER etd. Thetefore Missed connection from JFK to New Zealand . No accommodation provided… This cost ne aporox 1000 USD in extra expenses and turned whst should have been a 24 hr trip ftom Boston - New Zealand into a VERY expensive , late 70+ hr nightmare … Complete nonsense!!!

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

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.

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

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

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.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.

Unfortunately, spirits crew had us boarding and parking the plane often, would wait long periods of time before allowing the people attending the flight on the plane to know what was going on this caused for my plane to not only get diverted but then canceled at an airport 2 hours away and basically stranded with charter buses MAYBE being hired. I was left with no choice but to stay overnight and use a comp room in Altantic City to then arrive home the next day. This trip was the first time seeing my partner since he joined the Air Force and this stressful ride caused unwarranted tears on what was supposed to be an east flight home. I understand weather is unpredictable but to have passengers deboard to then reboard an hour later to taxi on the runway for another hour to then basically leave an entire fight stranded. I waited almost 30 minutes at the airport and not one employee could tell me about a charter bus so I had to leave and make accommodations to stay overnight and get a ride home.

This was the first time I use Spirit Airlines and was pleasantly surprised. It was a last-minute booking and I was happy to see there was availability on your airline for a price that was affordable. The staff was friendly. The only things I thought were missing, were the ability to recline the seats, although I don’t use that very often, and it would’ve been nice to have power access at the seats to plug in my devices.

Very good. Nothing more or less than expected. No complaints.

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.
