The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

Mediocre. Boarding is now unpleasant. The employees, once friendly and nice, are now regularly speaking sternly to passengers, badgering them to do things right so they can take off on time and gate check bags because they don't have enough overhead bin space. The pretzel snack was crushed flat and broken into even smaller pieces, which happens frequently lately. Drink service was suspended before they reached my row.

The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

It was canceled. Supposedly weather. But there was no snow in Baltimore. At least we found out before driving to airport

Delayed. Hot. Passenger next to me was so large I couldn’t move.

The flight went very well, but the flight attendants didn't serve and food or drinks other than 1st class due to rough air but to be honest it wasn't that bumpy and I felt that they could've at least offered water and coffee perhaps. Also serving 1st class only is a bad look. I've been in 1st class many times and I would've felt that if the turbulence was too rough for the main cabin, it would be too rough for 1st class too.

My seatback screen didn’t work so that sucked because that’s what I was going to do on the plane.

The whole experience was excellent. As it most often is with Delta

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Boarding and crew were fantastic, but I paid for a window seat with no window. Seat 11D on a CRJ-900 apparently does not have a window. Lesson learned.

boarded at 5:30 pm, pushed away from gate at 6pm ... takeoff was not until ~6:45pm; disappointing

Smooth boarding, pleasant and professional lady checking us in. Crew service was excellent, again pleasant, but professional. Nice touch-down on landing! Thank you Delta. 💗

Paid for wifi that didn't work. No plug in seat to work. No entertainment.

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

Much better than Spirit. I was please by the easy fast check in and boarding

Everything except the food and entertainment. It was a great experience though

The attendant on board was amazing. She should be doing business/first international long haul.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

Survey sent before we actually left. Delay after delay. Now a crew problem.

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

One day, I do so hope for a gluten free snack! Seems like with the rest of the world FINALLY figuring out what gluten free is, American Airlines would too. Fingers crossed!!

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.
