Our flight to Philadelphia was full and the gate announced that there would probably be a full state for carry-on luggage at Zone 5 of boarding. In reality, they announced that the overhead bins were full after Zone 4 had boarded. Passengers need to be prepared.

If you have any metal in your body (e.g., spinal fusion screws) make sure you get in the line for the TSA security screening booth that makes you stand on the yellow marks with your arms over your head. I wish I had known this before I wasted time in the alternate line with the walk-through detector.

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!

Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

2+hrs delay without any reason provided and a cramped flight

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight was delayed due to crew being not on time

Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

The seat cushions were very worn so they were extremely uncomfortable.

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

Flight was on time with no issues. Price is very competitive. Flight schedule works well for me

They charged late fees for selecting seats (no $0 options). They also changed my gate within the last half hour and are refusing to reimburse my costs to drive across the country with two small children in a rental car.

I was waiting in line for the restroom onboard, the flight attendant told me to step back two rows and stay on the carpet. She was rude and I expected a tik tok experience with me getting thrown off the plane. She was rude and frankly there was no where else to stand.

I needed a cheaper option than Southwest who are almost as bad as Spirit...did the check in the morning of the flight and assigned the last row, middle seat. Paid 20.00 at the airport for an exit row window in 19 and all 8 rows behind me which sold occupied on their seat map were empty....so they force to you to pay for a better seat....I was alone in row 19 and shortly after take off two huge fat people came and grabbed the other seats, I rang the call button for the attendant and said I paid 20.00 for this seat and they just moved in here...I either want to be reseated, or have them take their original seats or a refund of what I paid, the attendant made them move back to their original seats. Worst, worst worst airline in the air....never again, never again, never again.

It was cancelled a few hours before take off. Spirit has yet to confirm I will be refunded for the trip

gate agents with the different rules at the different airports. made me pay for my bag as a carry on instead of a personal item, yet it fit under the seat on the way from Indy to Ft Laud

charging $3 for really bad and cold coffee on airplane flight is ridiculous.

We flew Spirit because it was cheaper but the seats were so uncomfortable. I don;t need to be fed snacks on a plane but when it's a 3-4 hour trip then at least a drink is nice. The flight attendants had nothing to do the whole flight except for gossip loudly to each other right behind our seats, and they talked so much my husband couldn't even rest! I was fine with no tv or entertainment but the seats were so uncomfortable with no recline, no padding, and I am short but even for me to leg room was tough for a 3-4 hour trip. We probably would fly spirit again if we had to, but it's definitely not our favorite!

There was absolutely nothing good about this fight. They delayed us for over 2 hours to give our plane to a flight going to Tampa. By the time we got to norfolk conditions were too bad to land so they took us to Charlotte to refuel so they could fly back to Fort lauderdale. There was almost no communication from the pilot, no wifi, no chargers, and they wouldn't even give us free water when we were stuck in Charlotte refueling.

Checking in and getting to gate fast and leasy at Laguardia airport. There is no entertainment on the plane and food was for purchase. Great experience flying with spirit

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.

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

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.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.
