You actually took off.

Delta screwed up my ticket and booking and did not make their best efforts to accommodate or offer a suitable resolution. In fact passed the buck to TSA, who of course had passed the buck to Delta.......bad experience currently without resolution

Our flight left esrly and left ud

Cons: "Overall not bad. Food service can be better but it is due to the pandemic currently. Overall excellent flight!"

Pros: "Great crew. Old plane but comfy"
Pros: "I was fortunately upgraded to 1st class. The flight attendant was adequate. However, did not live up to the level of service I have come to expect."
Cons: "See above"

Pros: "When I finally got off the plane"
Cons: "Everything. No instructions, no pens or pencils, ignorant staff. Got to Cancun and waited 2 hours with no directions to just go they immagration. The forms were in Spanish and the staff could not translate. I’ll never fly Delta again."
Pros: "I did get home eventually"
Cons: "Flight was delayed. Seats are cramped."
Pros: "Flight crew was excellent. We had the emergency exit row so leg room was awesome! Kind bar and soda we good."
Cons: "Flight delay due to the older aircraft and lack of a pilot that knew how to fly it. Bathroom needed some tending to"

Cons: "Direct flight, on time arrival"
Pros: "The kind bars"
Cons: "They gave a hard time checking in because I didn’t mark I had a lap child. I honestly looked and the website wasn’t clear. Then (Bob who checked me in in Tucson) didn’t bag my car seat. And it came super dirty. I’ve never had an airline not bag the caraway. Especially when I asked. Southwest is a better company to work with. Disappointed"

Pros: "got to change my seat and have a spacious exit row"

Pros: "Seats were fairly comfortable, in flight entertainment was good, service was nice."
Cons: "Got to LA very fast but unfortunately had to wait 45 minutes to get our plane docked to the gate correctly. Don't think it was a fault on Delta or the flight crew but it was definitely annoying after a very long day of traveling."
Pros: "Short flight 21 min"
Cons: "Held on plane in Kzo awaiting clearance from Detroit . Kzo airport was great, clean, friendly."
Pros: "Crew service was excellent"
Cons: "Poor leg space"
Pros: "On time, nice crew."
Cons: "Delayed flight for 6 hrs. and acts like it is just business as usual, perhaps it is for Delta"
Cons: "The flight was very bumpy and didn't have the option to watch a movie."

The puddle jumper from Charlotte to Asheville often appears to be a low priority, if not for American Airlines then Charlotte International Airport. We had a tight connection (45 minutes), made worse by malfunction of gateway which took agonizing time to repair. I got no less than 3 gate changes, all in Concourse E, the farthest away from B where we landed. Fortunately airport people were great with a wheelchair for my wife, without which we would have missed the connection. Then, when we arrived at the resigned gate, the wheelchair attendant had to try times to get gate personnel to direct her to the right gate. Finally, when we went down stairs, we were redirected to a plane at least 300 yards from where we went down the stairs. If all that weren't enough, the two flight attendants appeared more interested in flirting with each other than paying any attention to the travelers. Avoid this connection if you can. Delta much better customer service.

Delayed little by little, so there was no chance to sleep longer or go out to eat. Missed connection flight and did not offer allocation, had to request it and $12 for lunch dinner and breakfast. No transport to hotel provided so there is another $120 in uber to get there.

Pros: "Goid"
Cons: "Hit heavy turbulence ,scary"
Pros: "Gate attendant was a superstar."
Cons: "6 hour delay due to part that St. Louis sent for - twice. Will never fly through ST Louis again on AA. Terrible Domino's pizza and water were complimentary after 4 hours delay. Returned to gate twice. 11 a.m. flight arrived at 9:30 PM ( 3 hr flight). Poor gate attendant was left to fend for herself as she was fed false and contradictory information."
Pros: "Boardered ok"
Cons: "They lost my luggage, crew member was short and impatient with elderly people sitting next to me."
Pros: "Gate side crew was amazing in providing repeated delay updates."
Cons: "6:34 flight was delayed until 1:00 am due to not having a pilot. No weather issues just no pilot, poor staffing. Unacceptable."
Pros: "Comfy seats"
Cons: "The crew"
Pros: "Fast and professional"
Cons: "Seats are really small, the A/C doesn’t work very well, very uncomfortable seats"
Cons: "Seat space"
Cons: "Delayed three hours with no communication or compensation. Poor customer service"
Cons: "Seats on American Airlines are the pits. So much so, that my back has gone into spasm. Bottom line, in future I'll do my best to avoid flying American!"
Pros: "Arrived early. Friendly pilot."
Cons: "Attendant did not offer snack choice."
Pros: "The crew is so friendly. Perfect landing. Perfect flight!"
Pros: "The flight was early."
Cons: "More leg room needed."
Pros: "It got us there"
Cons: "Beverage service was cancelled due to turbulence but I’ve been in flights worse and they kept their service Had to wait long for a ramp at a remote terminal then take 2 shuttles to terminal."
Pros: "Friendly flight crew and pleasant to interact with."
Cons: "Had a significant delay due to wind conditions in Chicago. However, instead of waiting at the gate, we waited over 45 minutes on the plane instead of letting us know about this additional delay prior to boarding. Also, the legroom was laughable, as the person in front of me hit my knees as soon as he began reclining."
Pros: "First class seating comfort and service. Even my flight in the main cabin was relatively comfortable, but I'm a smaller stature person so... On time promise kept every flight."
Cons: "First flight TUS to DFW was delayed by 3 hours causeing us to mist all the remaining flights. Had to scramble to find other flights DFW to LHR and LHR to DUB. We arrived at our destination 10 hours. No reason for the delay was given. Lousey service on AA."
Cons: "I’m not sure how this flight was as I missed it due to a delay from YYZ to ORD"
Pros: "Clean, Friendly flight attendant"
Cons: "I don’t understand how a brief meaning less than 30 minutes thunderstorm can cause a five hour delay. Every time I take the route from DCA to STL American is always really late"
Pros: "crew was pleasant"
Cons: "No free wifi"
Pros: "Flight crew very friendly."
Cons: "Everything was as expected. 1 star on entertainment as there was none. Would have liked to have been able to get 3 seats together without extra charges."
Cons: "It was nice. And boarding was good too."
Pros: "Nothing."
Cons: "Everything."
Pros: "On time. Nice plane."
Cons: "Not much leg room, seats are narrow."
Pros: "Nothing"
Cons: "All. Disappointed to see Etihad airlines declining so rapidly. What used to be my preferred airlines, not anymore and definitely can predict the downfall."
Pros: "Streamlined boarding process"
Cons: "Poor leg room and no video . Older plane."
Pros: "It was easy to travel"
Pros: "First class on TUS to ORD flight - very good flight attendant who was very pleasant, attentive and knowledgeable... she remembered which drink I was having."
Cons: "Plane was not board on time. Delayed taking off."
Pros: "Easy and customer service at lax was awesome and very helpful!!!"
Cons: "The 45 minute bag time that's it may or may not be able to go 45 mins within boarding ."
Pros: "This was the same crew and pilot from the flight I took to LAX. His landing was so smooth, I woke up pleasantly upon landing!"
Pros: "Great staff."
Cons: "The hour delay due to maintenance and fueling."
Pros: "Why would a jet this size wobble all the way across the Atlantic! The pretzels were even stale, and they served a "pizza" that was a stale mini loaf with sauce and a little mozzarella. People were starving when breakfast was served. The thermostat fluctuated from horribly hot to freeing - for 14 hrs. The crew slammed things down on table trays, grumped, were giving harsh orders to patrons rather than gently directing them. These ladies do not enjoy their job. I am done with Delta. We were also an hour late taking off due to a door on a cargo hold not closing. I was embarrassed that our Aussie friends experienced this as their first American flight."
Cons: "Food, attitude of flight attendants, comfort of cabin. Pilot took charge of thermostat issue and kept us informed in a friendly manner regarding the status of our take off and flight progress."
Pros: "On time"
Cons: "Boarding numbers"
Pros: "My neighbor."
Cons: "We sat on the tarmac for over an hour for no apparent reason."
Cons: "The airline did not inform us that the flight lands and passengers would need to travel by bus to the terminal. Just a surprise. I would like to know when booking the flight."
Cons: "I nearly missed my flight because I did not have a seat for a flight that I bought a ticket for at full price. Which, would lead one to believe that I would have a seat on said flight. However, coming to the gate an hour before boarding the personnel working gate the said he was having computer difficulties and could not get me a seat and it would be 10 min. I continued to return till boarding to find out I had no seat and I was on standby. Upon going to customer service they replied the airline oversold tickets and every airline does this as if to make this practice ok. Well being in sales myself and if I were to sell x amount of product to one customer ( or several) I better make sure I have it all there to deliver. People rely on you schedule wise. It nearly shot a meeting I had to make in the foot. Very disappointed with the airline and the way things were handled."
Pros: "Speedy boarding"
Cons: "Unmotivated crew, uncomfortable seats."
Pros: "We boarded fast and the flight was smooth. The crew was very friendly."
Cons: "The sears were a little uncomfortable. They went terrible but my back started to go out on my 2 hour plans ride."
Cons: "Boarding was chaotic, with people sitting in wrong seats and walking the wrong way down the plane. Crew were not especially friendly. I know it was at the tail end of a long Sunday, but it wasn't impressive."
Cons: "After having my flight delayed 4 hours causing me to miss my connection, I was placed stand by on a different flight through another city so I could try and make it home on time. I was the first person in line for stand by, but the flight was full so I knew it was a long shot. Waiting at the gate, I was excited because one person didn't show and they were giving him a two minute wait time before I could board. During this wait time a woman passenger came over and said she had just been given a ticket change at the gate counter. The agent at the gate was furious because the flight was sold out and said the woman should not have received a ticket, but should have been placed on stand by. She went over and scolded the other agent for this mistake. Okay, so she should've been placed on STAND BY behind me in line. After the unprofessional arguing between the two agents, they both admitted it was a mistake and she should be second in line for stand by, BUT they did not honor this and placed her on the plane bumping me. Needless to say, I missed my connecting flight because of this and extremely inconvenienced my family and in addition had to pay an extra 75 dollars out of my pocket to keep my dogs at their kennel an extra night because I arrived home 5 hours after expected. I understand that flights end up getting delayed and the agents are doing the best they can to accommodate travelers, but admitting a mistake and not fixing it to make it right is unacceptable. I notified American Airlines of my situation and only received a form letter with enough miles to get me 1/8 of a flight. I don't even care about the miles because I don't plan to ever fly with them again, I want the money for the dog kennel I had to pay extra. I was visiting my husband who serves in the US Army causing separation from our family for long periods of time and this extra headache and expense due to the mistake of American Airlines was disheartening."
Pros: "On time, arrived early."
Cons: "Seats too close in front of you."
Pros: "Flight was on time. Plane was clean. Staff very professional."
Pros: "The plane has improved greatly with their comfort and leg space"
Cons: "With checking my luggage my bag fee was waived a total of seven times this trip because I'm a military wife to see my husband overseas who is serving a year in Saudi Arabi except this past time on October 2nd at DCA airport. Spoke with the Supervisor Ralph who stated it was against policy. How stringent is this policy if it was waived seven times previously? Policy needs to be reviewed with entire staff. I will no longer use American Airlines because their military convenience and policies no longer seem to favor the military. My husband also after speaking with him will also no longer use your airline including all his members he overseas when they return after their year tour."
Pros: "The people"
Cons: "The seats are too small I'm 6'1 and that's not that tall"
Cons: "Several consecutive issues delayed our start, then had a weather hold before we could descend. VERY crowded, got stuck with a window seat with a very large man next to me--better than B or D, at least."
Pros: "I liked that it was on time and that I was a safe flight. The people at the checking counter were nice and helpful."
Pros: "Boarding was efficient and staff was great."
Cons: "Our trip was delayed 3 hours but Frontier gave us a voucher to say they were sorry for the inconvenience. But overall the flight was good and the crew were very professional and friendly."
Cons: "Seats super uncomfortable"
Pros: "Crew were amazing. Seats are very uncomfortable! Tiny seats and small space between them"
Pros: "The direct flight and the price Was excellent"
Cons: "Very good flight"
Pros: "Crew did fairly well under the circumstances. Clean aircraft."
Cons: "4 hour delay because frontier either doesn’t contract for or refuses to pay for deicing services in Phoenix. The pilot stated that Sky Harbor doesn’t have deicing services which I personally know to be false because southwest and delta both have deicing services and their is a deicing location at the airport. Instead we waited for the sun to thaw the airplane and further waited for a fuel truck afterwards. Only the first three rows have reclining seats that you pay extra for. I only recommend frontier for SHORT commutes, as the seats really are that uncomfortable with very little padding. NEVER AGAIN!"
Pros: "The flight itself was a nice flight. The captain and first officer were communicative and the few times we experienced turbulence I felt like they immediately tried to minimize it. I had a good amount of room in my seat (I was not in an emergency exit row) and I had no problems with my luggage."
Cons: "There was a 2 hour delay to take off. When your flight is at 7am and you've woken up at 3:30 or 4 to get to the airport on time, it's a bit frustrating to wait an extra 2 hours to leave. The gate agents were woefully uninformed and when they did communicate with passengers it was vague and unhelpful. The gate agents kept referring to the need for "maintenance" on the aircraft. It doesn't inspire a great deal of confidence in the soundness of the plane to hear that the maintenance crew is trying to "fix something in the cockpit." The Departures monitors and my Kayak app were giving me delay updates before the gate agents were. At one point we switched gates (it was the gate directly across from the original gate) and I watched as passengers at one gate literally traded places with passengers at another gate because the flights had swapped gates. It was comical. Overall, just a disorganized, uninformative, frustrating mess."
Pros: ".."
Cons: "The fact i got stranded."
Pros: "Nothing."
Cons: "The total cost of the flight is just a fraction of what you’ll pay. The nickel and dime you for everything. $38 for a carrying on, same for a checked bag. It was a quick trip and thought a back pack would be okay to carry on.... nope that’s $38, if you pay ahead of time. They charge more at the gate. When you check in they try to get you to pay anywhere from $9 to $21 to pick a seat. Seats don’t recline either. Flight was also late. You’re better off paying the full fare on another flight than flying Frontier. Never again."
Pros: "Pretty much nothing. I'M SORRY AS IT WAS MY FIRST TIME AND I have to tell you that I m usually pretty low maintenance....but damn ....this was was brutal! Price was was great... but not worth the experience."
Cons: "Seat comfort, cattle care of crew, no movie, no real food....you name it."
Cons: "The tickets look like a deal until they charge for every other thing. The information regarding what bag can be carried on without a fee is very confusing. We paid and then saw people rolling cases and putting them in the overhead bin. The seat prices are ridiculous so you don't want to pay for a seat they will assign you for free, I was then told I had to go to the gate to get a seat assignment even though I had already purchased a ticket. I waited for almost an hour before someone showed up. I was told the only seats left were the exit rows. Luckily I am healthy. If I have paid for a ticket Frontier should guarantee me a seat. We had to wait in line even though we had already paid for our bags and some of us went on line and checked in and had boarding passes. Where is the short cut then?? It was so convoluted we will never fly Frontier again. Too much work, let me pay for the ticket and let me have a bag and give me a seat for crying out loud. The flight crew was great. Very nice."
Pros: "Nothing"
Cons: "The seats and the trays are too small there's no space it's horrible and also Landing was horrible I thought I was going to die"
Cons: "11 hour delay .....Flight 740 From phx to den departure @6 am had a mechanical. First it was going to be delayed until 10 am them 11 am then 4 pm then 530 pm .it left at 6 pm . It got in at 9 pm by the time we got the car and got to out friend home it would have been close to 11 . We would have been up for 20 hours ( got up at 3 am to get there for a 6 am flight . We were going to a business meeting in demver in the morning in the afternoon a 70 th birthday lunch for my best friend. This trip was planned for months . We live in phx after it was clear we had missed both events we went back home @5 We ended up paying for a supper shuttle and a rent a car in Denver . We paid all that money To go noware the customer service woman there , was uncaring to everyone on board we were just on our own . I am heartbroken we missed the party ."
Cons: "My flight had a six hour delay and the whole Phoenix Frontier section of the terminal was packed because there were multiple flights delayed. All for mystery "mechanical" issues."
Cons: "They gave our captain to an Atlanta flight. We had to wait for another captain to get to DIA. Then we got loaded up and had to wait for the east gate to open, then they had to map out another plan I.e., the northeast gate (and that didn't materialize) soooo we sat on the plane until we receive the okay to depart on "the east gate". Which was approximately 21:30. We finally arrived at approximately 01:00 a little more than hour late. It took better than 30 minutes for us to get our luggage. Stupid crazy that a person is paying ridiculous prices for pitiful customer service."
Pros: "The landing was good."
Cons: "$40 for a carry on? Come on now. $5 seat upcharge because "window seat"? Chairs that don't recline? You interrupt my already terrible nap so you can try to sell the entire plane your "no-black-outs" Mastercard. The cabin was much too hot, people complained and nothing was done -- adding insult to injury, water costs money. Every aspect of buying a ticket is littered with popups to upsell you to something "better" or more "exclusive". The entire experience from buying a ticket to touch-down was dehumanizing and an insult my intelligence."
Pros: "The desk and gate staff was super helpful!"
Cons: "I understand that weather can't be controlled, but I feel as though more could have been done to get me to Philadelphia...even if that meant sending me to another city instead of Denver, for a layover."
Pros: "The trip was excellent, the flight boarded and took off on time, and we arrived early! Great flight"
Cons: "The seats are not angled to fit the figure of a person. The back of the seat leans back and the head of the seat is perfectly straight up. It meets at a point where that does not line up with the persons body height depending on the person. If you just leave it at one angle of give it the potential to lean back just enough, People will be that much more comfortable. I wasn't the only person who mentioned this on my flight, in fact I spoke with 3 people and overheard others complaints as well. One angle or at least a centimeter of space to lean back...I don't think it will mess with people behind them since there's no tv or entertainment and I think it will continue to bring more people into frontier."
Pros: "N/A"
Cons: "Frontier ingeneral. Very poor customer service, very uncomfortable, no accommodations for taller people with service animal, flight was delayed twice. Won't make that mistake again."
Pros: "I was almost late and they did everything they could to help me get to my destination including running my drivers license to me, as I was realizing at the security check that I had lost it. Then the crew was second to none and far better than other larger airlines. I'm sure most people know through word of mouth or their own experiences that they are sometimes spread too thin to cater to the customer anymore and this, however, was a fresh change of pace. I rarely take the time to fill reviews out but felt obligated in this case to spread the word through my gratitude. I had recently been laid off and they made sure I got on my flight for a job opportunity I needed. I thought the best part was the $59 ticket with tax but you can't quantify real costumer service like that. Thank you again to everyone at Frontier Airlines!"
Cons: "The plane was delayed an hour and a half because of a computer problem."
Pros: "I really did not feel any more crowded or uncomfortable than any other airplane Ive been on. I sort of like that the tray tables are the size of a large cell phone- less bulky than regular tray tables."
Cons: "The crew wasn't bad, just seemed unhappy to be there. There was some confusion with which gate we should be at, changed us three times before settling on the original gate. Boarding was no problem but then we waited without taking off for over 45 minutes. The pilot came over the intercom and informed us that he had no idea why we were delayed to take off, but that he would "find shortcuts" to get us there on time. The biggest gripe that we have is once we landed and went to baggage, several of us waited for golf clubs for close to an hour before a worker realized "they forgot" to turn on the button to allow oversized items to come out. Then she said "sorry I was busy with ticketing and Frontier doesn't have a baggage attendant". I just dont think the extra savings was quite worth the frustration."
Pros: "Updates and communication were helpful. Great prices as well."
Cons: "No free food or drinks. Too many extra fees like for bags and seat selections."
Cons: "The seats on Frontier are not comfortable at all. You can't recline. Also did not like the fact that you had to pay for both carryon and checked bags."
Pros: "Nothing"
Cons: "They changed the gate and told no one and the plane was delayed and they gave no notice"
Pros: "The initial fare seemed reasonable but they charge you for carry on as well as checked baggage big time."
Cons: "When we checked in for the return flight EVERY SEAT had a price tag, and the implicit threat was that your may not be seated together if you didn't pony up."
Pros: "The flight was on time."
Cons: "The crew people at the Frontier check-in desk were very unhelpful and rude. We missed our flight because we arrived at the counter to check our bags past the cutoff time to be checked in by 1 minute (due to long lines). That was partially our fault but the representative who was helping us did absolutely nothing to help us problem solve and seemed almost pleased to tell us that she couldn't take our bags. I rarely see such bad customer service. I have heard that Frontier pays their staff very poorly compared to other airlines and I assume this is why the customer service reps are so jaded."
Pros: "I liked everything except I was a bit surprised to find out it was an extra $40 for my carry-on each way. I would've paid the extra $80 upfront but it seemed a little bit sneaky to add it on when I got to the airport. Otherwise it was a very enjoyable experience."
Pros: "Corporate customer service lady was a complete jerk to me after frontier appeared to close early and didn't give me my checked luggage."
Cons: "As the other airlines were flying out of Denver despite the falling snow, Frontier cancelled almost every flight anywhere. Including ours. To their credit, they refunded our money, but its hard to need to go somewhere and the airline you've chosen is sitting on the ground. Very bad form."
Pros: "Assigned seating was comfortable. Flight not full."
Cons: "2 of 3 reading lights did't work in our row. Luckily I could move."
Pros: "Nothing other than getting from Phoenix to Atlanta"
Cons: "The baggage check in process at Phoenix is a complete joke. What is the point of prepaying for baggage on line if you still have to stand in line for over half an hour while you watch other passengers drop their jaws when they find out how much checking a bag costs, have the agents explaining the process and the price, fumbling for credit cards, processing the payments, etc, then, when you finally get to your turn, you are out of there in 30 seconds. There should be at lease one agent at all times who is dedicated to serving the passengers who do not need to pay. They should be in and out, not standing in line, when there is no payment to process. Then there is the total joke of the refreshments sales process on board the flight. It's not even worth going into that since I will never board another Frontier flight."
Pros: "pre assigned seats, more leg room on A321 than Boing 737, clean cabin"
Cons: "zone 4 boarding"
Pros: "Landing was ten times better landing in st louis than kanding in phoenix...cabin pressure dropoed quickly coming into phoenix.. Very even drop coming into st louis"
Cons: "Should provide at least a cup of ice water free..did have that going to phoenix from st louis...but nothing on way back..."
Pros: "I was very surprised at all of the small things and extra charges that you had for the flight. For example, even just paying for a soda on board I thought was a little overboard. And then once my flight was canceled they were of no help on rescheduling my flight and were not able to find another frontier flight for four more days. Myself and others were left to reschedule our own flights without any repayment of the difference in ticket price. I will not fly this airline again I caution everyone else at the lack of customer support and professionalism ."
Cons: "Frontier cancelled the flight. Their alerts to my email came well after I arrived at the airport. The single check in attendant didn't offer an explanation and curtly told me next flight wasn't until 3 days later. Plus, you can never reach a person at customer service they won't guarantee a refund since I bought a discounted flight."
Cons: "The Huge weather delay has nothing to do with Frontier since the weather is out of there control. All I can say is you get what you pay for!"
Pros: "Fast flight, nice crew."
Cons: "Extra for luggage, charging for water, 4 hour delay."
Cons: "We have been delayed 2.5 hours and still waiting. No one has been at the desk the entire time to give us any updates or information. Our message board behind the desk still says we were departing 30 minutes ago. Pilots took forever with pre check"
Pros: "I appreciated that we were allowed a purse as individual carry on. They do charge for carry ons, so check the measurements of your bag. They didn't appear to be too anal about it, but $60 charge at the gate wasn't worth it."
Cons: "Misleading during online check in about paying extra for more "valuable" seats. If you really don't care, don't pay extra unless you like giving away your money."
Pros: "The crew was nice, flight on time and fine."
Cons: "I don't like the fact that you do not recycle, yet you provide goods that are just placed in landfills and will take hundreds of years to decompose. The airports recycle, is it that difficult to make that happen for Frontier? The hundreds of plastic cups, plastic bottles, cans, etc. etc. is mind blowing and is something I pay attention to. I actually took my item back to the airport instead of giving to the crew at the end so I could place the item in the recycle bin in the airport after asking your crew if there was recycling. They said there was no recycling. I also picked up a plastic bottle from another seat on the way out to help clean up since I knew you guys would throw it out anyway. Thanks for considering being more sustainable, eco-friendly, and for thinking about my comment seriously to minimize your airplane's environmental impact. I will pay attention and voice my concerns elsewhere as well - recycling shouldn't have to be done by the consumer, the businesses need to step up and make it happen."
Pros: "My initial flight from Denver to Phoenix was a hour late, but lets talk about the way home.... Flight got in OK and then we waited 45 minutes for a gate to open. Could you park us at another gate? That would be too simple. When we parked we waited another 20 minutes while they put a jet way in place. Now answer this... the other plane just left that spot, so what happened to the jet way from that plane? Do they completely take it away or just fold it up? Fold it up I bet , so it was in place just had to be opened up. I guess they couldn't find anyone to do that. I know this sounds petty, but I have never taken a Frontier flight that went smoothly. Thank God I haven't had to take many. And it's not as cheap as it looks by the time they get you for bags and a charge for your seat. I ALREADY PAID FOR MY SEAT, WHAT'S THAT ALL ABOUT. Bye Bye Frontier, I'll pay more for the service issues."
Pros: "price reasonable"
Cons: "this was the most uncomfortable seat I have ever sat in. the upholstery was so thin, no head support , no leg room, ridiculously small tray table paying for a soda??? and then having a choice to tip"
Pros: "Honestly at first I liked how it appeared to be a newer plane with updated seats but then..."
Cons: "I saw those updated seats and the joke of a tray table that was provided wouldn't even hold my iPad. The staff was apparently new because they couldn't get through one intercom conversation without fumbling through it and when a customer asked how long the flight was the flight attendant didn't know and another passenger had to answer. We were delayed by 2 hours and all because the intercom phone was broken. I know it's a safety hazard but it just wasn't a smooth professional staff that you typically see. One of the three flight attendants was tenure but all I saw was the new girl fumble through everything. I'm hoping she was new...also, we are delayed two hours sitting on the plane, so I know people will give bad reviews about that but there's nothing you can control regarding our safety. It is what it is, I just couldn't stop shaking my head everything they spoke on the intercom how bad they were on it."
Pros: "The price was excellent and staff very friendly. Landing in STL was very smooth...pilot did a super job."
Cons: "There was a mix-up in the baggage loading, thus we were delayed about 40 minutes or so...it seemed longer since it was a late flight. The attendants were very nice, air-conditioning made it all comfortable during the long wait. I totally understand how accidents can happen and I think the crew handled the delay very well. The attendant was very nice and during refreshment service, my daughter asked for 2 glasses of water and she gave them to us. We had not planned to be on the plane so long so I had not brought along anything to drink. All in all, it was a good flight. Thank you."
Pros: "This was my first flight on Frontier and didn't know what to expect. When my iPhone boarding pass wouldn't work at security I was sent to the Frontier counter and they helped me instantly. The Phoenix boarding lounge was NOT a good introduction with holes and rips in the seats and a "sofa" that rocked everyone on it whenever someone moved.. The gate attendant however was great - and funny. The plane was VERY nice and made up for the lounge plus we made it to Colorado Springs 20 minutes early! The price ($56 including fees and taxes) means I'll be looking at Frontier in the future."
Pros: "It was on time."
Cons: "Uncomfortable seats. Tray tables were too small."
Pros: "Seat size and leg room."
Cons: "I had called to have a wheelchair ready for my 90 yr old mother. No wheelchair. Luckily someone helped get one for her, but I had to push it while pulling suitcases. Very disappointed because I had called the day before to verify the wheelchair. No free beverages."
Pros: "The flight attendants did a good job."
Cons: "It was annoying to have to pay a $30 baggage fee on the way there and on the way back. Also, they offered no movies or entertainment on a three hour flight."
Pros: "There was a gate issue in PHX, but they found another gate and we still arrived on time."
Cons: "I do not like random seat assignment. I was not aware of this until check-in."
Pros: "The cabin was clean, and the staff was friendly."
Cons: "I was disappointed in the surprise costs of luggage. I packed everything in a carryon so that I wouldn't have to pay for a check bag, but turns out a carry on costs $40 at check in. I understand it was a cheap flight, but I may have made a different decision if I knew there was an extra hidden cost of $80 round trip. On other notes, on the first flight of my two, the plane was swerving back and forth on takeoff and landing. The weather was fine, and I've flown plenty enough to know this wasn't normal. My second flight was fine. It was on the same plane, but the crew changed, so I guess it was pilot causing it to be this way? The seats were uncomfortable in coach for long periods of time compared to other airlines, and did not recline."
Pros: "Not much."
Cons: "First and LAST time flying Spirit. Once I had to pay the fee for having a carry on bag, the price came out closer to one of the airlines I should have used instead. The website address didn't even work from my phone, so I had to pay the $65 gate fee for the carry on. The seats weren't comfortable, didn't recline, no cushioning. No inflight entertainment of any kind. During the flight, I got up and went to the front to use the bathroom (which I KNEW was empty) and the staff directed me to use the ones in back. Why? And they never reduced the cabin pressure on the descent! The cabin was still completely pressurized for the higher altitudes well after we touched down. This feels like such an amateur mistake that simply isn't acceptable."
Cons: "Luggage never came"
Cons: "Be on time"
Cons: "Being charged double for check in bags was a waste of money, and given no explanation on why our flight was delayed is ridiculous."
Pros: "Hard to name"
Cons: "almost everything. Very uncomfortable seats! Especially, was shocked by not giving me even water during long flight unless I pay money"
Pros: "Nothing"
Cons: "That the prices are quoted slightly below market rate is a bait and switch tactic. There was zero baggage allowance for an international flight (never heard of this) and even carry one is charged at $55 to $65! If you pay online it is $10 less but at the cost of surrendering a lot of your personal information to be spammed ad infinitum. I paid my $55 at the airport because I wa forced to, but to my surprise I wa charged 3 times for a total cost of $165!!! All of the flights were delayed! The chairs don't recline - I gusess that too requires extra fee. You are better up paying $50 or $100 extra for a better experience, comfort, respect by any of the major carriers."
Pros: "Fun, friendly atmosphere and great prices."
Cons: "Know that you will pay $56+ at the counter for your carry-on. A small, backpack or smaller, bag is free."
Pros: "The passengers around us were friendly."
Cons: "There wasn't enough leg room. Every time we turned around we were charged extra. Our just under $400.00 dollar flights ended up costing us just under $700.00 by the time we were done compared a different airline we were going to take. Someone suggested to take Spirit because they were less. The other airline flight would have cost us a little over $500.00 total. that is a huge difference and we would have had bigger seats and leg room and NO charge for water. All the people around us were complaining about all the charges even saying we will probably get charged to get off the plane."
Pros: "Nothing I don't think I would ever fly it again it was cancelled and jerk us around and jerked us around ."
Cons: "Don't think I would ever fly it again"
Pros: "Every time I did something it cost me. You talk about low prices, by the time I paid for luggage and seats both ways I could have gone to a more expensive airline and paid less. Never again"
Cons: "I know Spirit offers low fares and in return you pay for everything else, seats, carry-on bags, boarding passes (if you don't print yourself), drinks, etc. In knowing this I did my due diligence before this flight to make sure I wasn't going to be charged for things like the size of my purse (I measured it), etc. Upon check in for this flight, I was informed that I owed $30 because my checked bag was 43 lbs and Spirit has a weight limit of 40 lbs. The other customers in line were just as shocked. To me, the standard is 50 lbs. With that being said, in my research on Spirits website this was not clear. I think this sort of fee should be much more prominent. I am a "prepar-er" if you will and for me to not know this charge was coming tells me Spirit most likely makes a lot of money off of passengers regularly having to pay this unexpected fee at check in. The ticketing agent told me it happens daily after I asked him. This feels a bit like a scam, in my opinion. Spirit will say "It's on our website" and I'm sure it is but again, I don't feel like this charge for a weight that's standard is 50 lbs is clearly called out to passengers. I'm fine with no frills, I'm not fine with unexpected charges that I feel are under the radar until the 11th hour when you have no choice but to pay or repack. Uncool, spirit."
Cons: "My 96 year old mother's Spirit 342 flight from Phoenix to Minneapolis on Feb 2, 2017 was delayed. Things happen and that's life. However, after hearing from my sister in Minneapolis her flight was delayed I attempted to call Spirit Airlines to get the rescheduled information. I tried many, many times and was not able to speak with a Spirit customer service agent. In fact, there was no option on the Spirit phone message to press a number to speak with an agent. I ended up calling the Phoenix Skyharbor Security who sent an employee over to Terminal 2, Gate 2 to look for my mother. She was not found after checking Gate 2 and several other gates. The scheduled 3:07pm departure was rescheduled to depart at 5:30pm which I found out around 7:00 pm Phoenix time. This was a frightening experience for our family given my mother's age of 96 years. Fortunately, my mother was OK. She stated she and everyone else stood in line at the Spirit counter for 1 1/2 hours waiting for departure information. There was an agent at the counter but he/she did not provide any departure information let alone the reason(s) for the delayed flight. It would have been helpful to everyone held up by the delay to have been given an honest reason for the delay. It seems reasonable that Spirit would at least offer a phone number to speak with an agent who could provide information. (The Spirit website indicated Flight 342 was rescheduled to the next morning (Feb 3) with a departure of 8:00 am. This incorrect information complicated the whole situation). We will never put my mother on another Spirit flight and will think very carefully about using Spirit Airlines again."
Pros: "Flight left on time and arrived 30 minutes early No waiting for a gate to open"
Cons: "Seating pitch is too narrow for a tall person. I was limping as I got off because I could not extend my legs."
Pros: "Staff were nice, funny, and accommodating."
Cons: "n/a"
Pros: "Delayed twice, yet still no email informing us of the change."
Cons: "The flight was delayed two hours, then without notice they moved the fight up in time. It was extreamly difficult to rebook a new flight, which was on a differently airline."
Pros: "The boarding process went quick and smooth especially since we had 3 small children with us. The ticket prices are nice but with all the extra fees it's like highway robbery"
Pros: "Friendly, great service."
Pros: "nothing"
Cons: "the total experience was awful. Uncomfortable seats."
Pros: "Everything went smooth."
Cons: "All the fees were too high and didn't like that they go up if you don't do it right away. I paid for a carry on and then had to check it and it cost me $5.00 more for a lot smaller bag what a joke! Large suitcase $50 little carry on $60 way to high!!!!!"
Cons: "Flight to Denver was loud not a good flight attendance Was very poor"
Cons: "My flight was booked for the wrong day. I only had one day selected on Kayak.com so I never thought to call in and verify time and date. I was signed up for text notifications but I never received anything."
Pros: "Crew was funny and made the flight entertaining at such a late hour."
Cons: "The crew"
Cons: "They were late every time They lost and damaged my baggage, found some of it, but won't pay for anything missing or damaged. I paid for extra leg room but didn't get it won't fly them for free, ever again!!!"
Pros: "Nothing."
Cons: "I spent 7 hours sitting in an airport with nothing to do spent more money at the bar in the restaurant and with my baggage then with the actual ticket cost plus I made it 9 hours later"
Pros: "I liked that the lady working at the gate had empathy for me and understanding why I'd be upset for not knowing that I would be charged $55 at the gate to carry on a bag. She was nice and just doing her job despite having a large unexpected fee."
Cons: "Not being aware that I would be charged $55 to carry on a bag. That was totally unexpected. And according to the person working the gate, if I had known they charged for carry on bags, I could've paid at the time of the ticket purchase and paid only $22."
Cons: "HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!! HORRIBLE !!!"
Pros: "However they gave FULL refund and a voucher. Much appreciated."
Pros: "Plenty of room on plane. Clean plane."
Cons: "1hr delay when landed. 2hrs for a1hr flight :-( Bud light beer only! Whatta!? Really? Charging for everything! Seats, bags, a drink and a snack! Tried to "save money" flying Spirit... Ended up saving only 20% vs southwest and that 20% was def not worth the aggravation,delay, and lack of any real customer service. All we heard was "sorry for the inconvenience" from the pilot on the intercom lol.. Did not seem authentic. Truly disappointed as a consumer. Will not fly Spirit again even if it were free. I'd rather drive."
Pros: "The "seemingly low price" was very low, and is what sucked me in in the first place."
Cons: "The fact that my baggage cost more to ship them than the price of the ticket in the first place was a huge surprise. That will not happen again! The seats are cramped and comfortable only for a flight lasting less than 90 minutes. If your flight time is longer, be ready for a very sore bottom."
Pros: "Early arrival. Cheap."
Cons: "No customer service to speak of"
Pros: "Great rate!"
Cons: "No free soda lol"
Pros: "I loved that it was clean, on time, and the flight crew was nice and very hilarious! Made it very fun!"
Pros: "Everything was good"
Cons: "NA"
Pros: "I loved the humor the crew worked into the mundane aspects of flying."
Cons: "I did not like having to pay an additional 45 dollars to bring on a cary on that seemed a bit steep in price point."
Pros: "Overall the web site looks like it was successfully intended to be attractive and it contains all the needed info."
Cons: "*Promising to answer a question "within 48hrs" is NOT OK when it is about checking in. *We SHOULD NOT have to register in order to be able to check in. Why is more than conf # and name needed unless it is to be shared or sold? *The needed info is scattered in many places on the site eg bag size, weight, and prices. *I was charged the "at checkin" price when I used the add baggage link before starting to check in; b/c I was within 24hrs? Purposely didn't start to check in yet so I wouldn't get the higher price."
Pros: "The service was very easy to use, loved it."
Pros: "$45 Phoenix to LAX. Can't go wrong. My carry on easily met the requirements for the free bag. If you're going away for more than a long weekend probably makes more sense to fly another airline."
Pros: "Left 45 minutes late due to maintenance."
Cons: "Late arriving at next destination"
Pros: "The affordable fare price"
Cons: "Wish they would offer similar fare to salt lake city"
Pros: "The customer service was great and very funny flying attendance. My flight was very fast and comfortable. Thanks"
Cons: "I didn't like that I had to pay for my carry on luggage more than I pay for my flight ticket :/"
Pros: "No-frills"
Cons: "Tighti seating"
Pros: "Quick"
Cons: "Bumpy"
Cons: "My flight and all other flights to Minneapolis were cancelled that day. My only option was to reschedule for the following day. Instead of dealing with that mess, I got a refund and booked a different flight with Delta. The whole experience has put a negative taste in my mouth for Spirit Airlines. Will not fly again!"
Pros: "Flight was safe."
Cons: "Luggage policy, no drink, last time I had a very rude boarding person from Spirit treat me the worst I have ever been treated from an airline."
Pros: "The price of the ticket"
Cons: "Was delayed almost 2 hrs and was already a redeye flight. Cramped seating and have to pay way too much at airport for a carry on."
Pros: "Crew was nice."
Cons: "Delayed for 3 hours!!! Flying out and coming back home, we had major delays due to mechanical problems. No excuse to have that long of delays if they were keeping up with the maintenance on the planes like they should. I will NEVER fly Spirit again!"
Cons: "I could live with the extra charge od $55 per bag on the Denver to Phoenix portion of the trip, but they cancelled the flight an hour before leaving Phoenix to Denver. This left 100 people scrambling to find an alternative flight. Rather than wait 1-2 hours while two totally unprepared ticket counter clerks tried to accommodate 100 PO'd travellers, I decided to get one of the few tickets available to Denver leaving that day. It cost me $375. I finally got thru to the Spirit Customer Service desk (somewhere in the Philipines?) where somebody did try to help, although the line was sketchy and the accent indecipherable. I recommend not listing Spirit on your site."
Pros: "I arrive home"
Cons: "Extra Charges for everything. Seats do not recline, etc."
