Exceptional. The gate crew responded quickly and got me onto this earlier flight as the final passenger, saving me more than four hours of wait time for my reserved flight.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

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

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

Very good. Sad to learn Southwest is going start to charge for bags

Exceptional crew! Friendly and professional. Pleasant attitude and treated everyone with respect.

The flight was promptly on schedule and Southwest delivered everything they promised. No excuses for any shortfalls just 100% ownership of their responsibilities and business. The boarding and seating policy is a complete shambles. What started out as a great idea when Southwest first hit the market has been turned into a disaster due to the lack of integrity in many of the people who fly Southwest and take advantage of Southwest generosity at the expense of their fellow passengers.

Crew was excellent - Plane was fine. Media was good, could use more kid shows; Not a fan of the brownie brittle -- snack could be slightly better.

Left on time and arrived early. Brand new plane and no parts missing. Comfortable seats. The actual Captain spoke prior to the flight and reassured everyone about safety. Crew was so nice and fun. Perfect flight!

Everything went smoothly and the plane wasn’t full. It was delayed though. The delay was increased due to a crew change which was frustrating.

Your survey needs a N/A option. I didn’t use the entertainment or eat food.

Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.

Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

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.

The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.

We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

Fine not above and beyond as I had a connection that was delayed due to maintenance

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

Onboarding - it would be great to see on the screen what group they were boarding. It was very confusing on who was boarding (even though they called it out) they were not clear and the space to board was strange.

Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

No enough space plus only allowing one laggage instead of two like other airlines.

Qatar airways ,boarding arrangements at Hamid international airport could been better

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.

Frontier is good until they cancel your flight. Way too many cancellations.

I know Frontier is a “no-frills” airline. I understand the concept. However, I jumped on some tickets for our family vacation, expecting to play a bit of a game to figure out the family bags and not over spend. In the end, I got the short end of this deal by far. 1. I did not expect them to charge the baggage fee for each direction. It makes the fee look high-ish at a glance, but reasonable. Then when you get to checkout and realize you have to pay it twice to come home with your luggage, it becomes ridiculous. 2. The low checked bag weight limit. I am used to packing a 50lb bag with my preferred airline. Frontier’s artificially low 40lb limit more quickly triggers the extra weight fee, which almost DOUBLES the price of the bag if you go over ($79 for the bag/$75 for the next 10 lbs) 3. The fee for a carry-on bag is the same as a checked bag but with a lower size and weight limit. Make it make sense! 4. The seats are terrible. My 2.5 hour flight almost had me losing my mind. I’m 6’3” and my femurs barely fit in the space provided. My knees had to wiggle just right to jam into the crack next to the armrest of the seat in front of me. The cushioning was thin and inadequate. I am tall but I’m not a freak. These seats are unacceptable. 5. I overheard the woman next to me speaking with the gate agent about being charged a $25 fee for not checking in online - she checked in at the airport counter when she arrived. That’s ridiculous. She was old and in a wheelchair. She had a paper boarding pass, and was obviously not tech savvy. She should not be punished for that. 6. They do not have good placement in the terminals. It was always out on the end or down on a subfloor, and we had to walk out on the tarmac almost every time. In Denver. Their home airport! 7. Every time I loaded a new page on the website while buying my tickets or my bags, it was constantly trying to upsell me on some esoteric bundle. Like, a pop-up every time. Very annoying. 8. No screens in the boarding area (at least where we were) to confirm you’re in the right place. Just static gate number signs. I am sure these are standard practices for Frontier, and I should have read more about them before I purchased tickets, but as a result of this single round trip, I do not plan to ever use this cut-rate airline again. I would rather pay the normal amount for a ticket and be treated like a customer instead of a mark.

Our flight was delayed 2 hours and when they changed the the time to 1 hour I wasn't alerted and when I checked the gate the plane was still there but they already shut the doors so I had to buy another flight.

Great except upon arrival it took them a long time to open the doors

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

Terrible. Delayed my family flight for several hours affecting family plans

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

The seats are tiny and they don’t recline. The planes are dirty and very small. You have to pay for carry on and even the personal item that you’re allowed is smaller than with other airlines. Flights are usually delayed and there’s no screens or any amenities or entertainment.

I have come to accept Frontier as an absolute no-frills airline, paying for everything I want. A 4.5-hour flight should provide me with a complimentary beverage—rather, $4.9x for a soda. Or a bottle of water ought to be extended at no cost. 4 beers are on the menu, but only 1 type of beer is available (at $9.95). Also, so many restrictions to using a voucher from Barclay‘s Credit Card. Finally, try to reach a live agent for Frontier- impossible!
