Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

I didn’t not like that I could not select my seat and ended up with the worse seat.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

All good except paid for wifi that did not work

Some of these FA’s need attitude check. Snarky bitches

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Flight was canceled 12 hours before take-off due to “weather”

The flight was short and that was the best part. The flight was about 90 minutes delayed.

I got upgraded, so comfort was not an issue. But as always, it is the people from baggage handlers, flight attendants, pilots etc. that make the difference.

The lady who gave me my boarding pass for check in was extremely rude.

Did not like the seat spacing. The seat was very narrow and tight.

The crew were great. The boarding process was unclear where to line up. Plane was very old. Flew on a new plane flying from LA to Houston. Business class was great. Plane from Houston to Merida was very old. The plane from LA to Houston made me think I should fly United more. The plane from Houston to Merida made me think I should stick with Aero Mexico and Volaris.

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The flight was so short that the lack of leg room didn't bother me for long. The plane was smaller so only two seats per row and there were chargers. However, they didn't serve any snacks.

3 hour delay was brutal though not Spirit Airlines fault. the control tower would not let us take off because of weather

Beware of all the extras. Nickel and dimed. Everything was extra. It turns a $90 fare in to a $400 fair quite easily.

It would have been nice to have been on the flight

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

It wasn’t as horrible as I would have expected, however, to not provide water and change so much for bags is a ripoff to say the least.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.

Good except my suitcase was completely broken when it arrived on belt. Now I have to go through a process to try to get ANY back. Not happy

They changed our gate 30 minutes before boarding began. We noticed about 20 people missed their flight due to doors closing early.

I hope to avoid flying with them in the future. First flight got cancelled then got stuck with a 13 hour layover in Denver. The process was long and frustrating to many people.

First time flying Frontier, I am not sure the Ala Carte menu of options is for me.

Flight was delayed on the runway for 40 minutes the crew did not even offer even water to passengers to compensate for the flight delayed. The flight was delayed due to aircraft mechanical issues. Worst customer service ever

See my previous comment which is mostly about our flight from Phoenix to SFO

Terrible. Initially we were shocked by the outrageous baggage fees we needed to pay at check in for our so-called "discounted, economy flight" - we paid over $200 (!!) for one check-in and 2 carry-on bags - this felt like a real bait-and-switch" scam. Our flight from Phoenix to SFO was delayed by 4 hours. Multiple apparent causes (from needing to make space for other planes that were landing late to problem with cabins pressure system, and whatever...). After de-boarding and re-boarding we still waited at least an hour on a cramped, poorly ventilated plane before take-off. Seats were cramped, uncomfortable - did not recline at all. No water until we were flying for a while. No complimentary snacks. Upon arrival at SFO my luggage was sent upstairs to the check-in counter. The customer service person there refused to let me examine a bunch of bags that were sitting on a nearby cart because it was "behind the counter", rather made me wait until another attendant did an exhaustive and failed (?computer) search, came back and told me they were unable to locate my bag. I asked her to look on the cart, lo and behold, there was my bag just a few feet away! Missed my choir rehearsal that evening due to all of the delays. One more thing, a few days later my husband and I tested positive for Covid. Since we both are fully vaccinated, careful about masking and have never had Covid previously, we will never know, but suspect we may have acquired the infection during the prolonged wait on your poorly ventilated plane (person in the row in front of us was coughing). After registering a complaint, we received a measly $50 voucher for future flights. Needless to say we have no intention of flying with Frontier Airlines ever again.

I liked getting off the plane. Everything else was well below standards. Not even offering a bag of peanuts for free for a 4 hours flight is ridiculous.

The whole experience was bad. Didn't know no complimentary drinks or snacks. $4.39 for a soda is ridiculous even a bottle water. A carry on was $74 just crazy. I don't think I will take this airline ever again. Very bad

Delayed...attendants checked every single bag and item for sizes before boarding.

There was no wifi, there was no usb charger on the planes Frontier lowered the weight limit on suitcases from 50 to 40 pounds Frontier now charges for a seat...really? If i don't pay for a basic seat, do i stand the whole flight? Frontier now charges for the carry on, just like for the checked suitcase The bundle pricing is way over priced.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.
