Pros: "Very helpful and professional crew, despite some pretty snarky passengers. Seemed to go out of their way to accommodate everyone."
Cons: "Bigger seats would have been nice, but these were okay. Changing planes at JFK was tight due to late departure from Atlanta, but it worked out. Overall, no complaints and I would fly Delta again given the opportunity and choice. Thanks!"

Cons: "It was ridiculously cold for 2 1/2 hours. When my seat mate asked for a blanket, the stewardess said she only had one more - then walked off. For drinks, they skipped several people. I had to catch her eye to ask for one and then ask her to get my kids a drink in front of me."

Pros: "All the attention bestowed upon me"

Cons: "Left A bag behind in NY"

Pros: "Lots of leg room, smooth flights and plenty of notification of any upcoming turbulence. Delta did fantastic with keeping everything from check-in to landing friendly and professional. Will definitely fly again"

Pros: "I am usually happy with Delta."
Cons: "Huge smelly person invading my space. Disgusted by his hot sweat on my leg. Used up 10,000 miles and paid too much (watched the fare go down several hundred dollars) and ended up with a middle seat. Not happy."

Cons: "If there could have been some sort of service at DTW to take customers to the gate of their connecting flight, for cases of really short time window of course, it’d be extremely helpful."

Pros: "Crew were ok. Not that comfortable."
Cons: "seat need to be more comfortable"

Pros: "The crew"

Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "Great service all around"

Pros: "Nothing including the captain who was making the boarding announcements at MCI who talked to me like I was stupid"
Cons: "My flight was delayed almost two hours which caused problems for me arriving late to business appointments in New York. My flight areas also late 45 minutes leaving New York. In both cases it was due to a late airline attendant this is increadably unprofessional."

Pros: "Flight was comfortable. Short, sweet, and landed before I knew it. Boarding was a smooth process."
Cons: "The flight crew and service on the plane was fine. My biggest complaint was at the baggage drop off at the airport, where there was quite a long line without any crew members assisting us. A five to ten minute wait is fine, but a fifteen minute wait, with only three crew members compared to the other airlines? By the time I dropped off my baggage, the other airlines were finished with their customers, and there was still quite a line behind me."

Pros: "the flight was on time and the staff very helpful"

Pros: "Not the wor st comfort,"
Cons: "Cannot even request seats before booarding, as they try to get us to pay more. The anxiety over separate seating for couples is not worth it."

Cons: "Still pretty cramped, not the crews fault. Would've been better with the seat back screens"

Cons: "My email read check into Aeromexico I could not check in the Aeromexico using my phone I was dropped off at the Aeromexico terminal after standing in line for half an hour I find I was in the wrong terminal I needed to be in a different terminal with Delta because Aeromexico even on my reservation read that does not fly to Tampa. I had to find a shuttle to another terminal the shuttlesare not marked it was very confusing"

Pros: "Enough said"

Pros: "Good uneven full flight"

Pros: "I had a great pilot on this flight. He always told us what was happening, why we had a wait on the tarmac in LGA, why he anticipated it might be a choppy flight, how to access in flight entertainment so we could be distracted.

Cons: "Seats were uncomfortable. But what else is new?"

Pros: "On time, kind crew"
Cons: "Bigger seats"

Cons: "Thank reserved seats at time of purchase for a British airways plane and paid for extra legroom. When I checked in, I was routed to American Airlines and the seats were the same in the entire aircraft except for first class. Why did I pay and shouldn’t I get a refund?"

Pros: "Trip was wonderful."

Cons: "My son and I had seats in different places and they asked him to move forward several rows because of weight and the seat beside him was empty so I asked if I could sit next to him and they said no without giving any explanation. That kind of upset me. Just a short explanation would be fine."

Cons: "I expect better service from American Airlines, total disappointment. Given incorrect information by 2 gate agents concerning connecting flight delays."

Pros: "The flight attendants were able to find a place for my carry-on luggage when the overhead bins were filling up. I got a seat with extra leg room by chance (without having to pay the extra fees)."

Pros: "Quick boarding, smooth on time flight. Easy access to DC from Reagan airport"

Pros: "The whole experience was stress free and comfortable."

Pros: "Nothing"
Cons: "Delays when other airlines with same destination did not have them. The constant asking if is move seats. No means no."

Cons: "See above"

Pros: "The American Airways gate agent was very helpful fixing the problem that British Airways created. She went out of her way to get me booked on AA flights to catch my BA flight from London to Riyadh."
Cons: "My original flight was cancelled and the first available flight was 3 days later. BA booked me on the flight but failed to change my ticket from the original flight causing me to miss the flight from Kansas City. At the airport BA agent told me on the phone that I would have to wait 3 more days after I had already waited 3 days because BA canceled my original flight. Because of the flight cancelation I missed two days of work and because of the failure to ticket my following flight I almost missed a full week of work. The BA booking person seemed content that there was no way I could make it to Saudi prior to the end of the week. Fortunately, the AA agent was able to find a way for me to continue my trip on a later flight."

Pros: "On time. Friendly."

Pros: "On time"
Cons: "Dirty plane. DIFFICULTY hearing which baggage kiosk to use. Should have a board with postings"

Cons: "- The entertainment system was not working - needed few restarts - on many seats - Food - horrible - Air hostess dropped water on me - not a problem by itself as accidents do happen. However her comment was more annoying - no sorries - not apologies - just said - "oh it's just water - it is refreshing" - Seats pushback was almost broken - it would break your thumb to push the button and then almost stand to push the seat back. - This was transatlantic flight and you charge for liquor? It is not free - you have to purchase - They ran out of red wine (which was free) by the end of the first meal. Do you keep just one bottle for this big 777 fight. - Overall experience was horrible."

Cons: "There are hard to reach outlets and no ports to charge a device without a box. Also, no monitors."

Pros: "Nothing"
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"

Pros: "Nothing"
Cons: "The boarding process was chaotic and the plane attempted to land once, got about 100 feet from the ground and had to pull up. So we basically landed twice."

Cons: "Sat on tarmac in United plane at destination (Denver) from 2:40 pm to 3:35 pm. Waiting on a gate to unload...just long enough to miss my 3:30 pm United connecting flight.

Pros: "Easy to board friendly"
Cons: "The snack food selection, price on wifi"

Cons: "A passenger had to move because of an allergy to the "emotional support dog" in the seat next to her. They moved her before the rest of the flight had boarded, so the seating got messed up and took quite a bit of time to sort out. The flight crew seemed to be extremely put off by the whole scenario and couldn't seem to keep their displeasure professionally under control. I ended up volunteering to move because the passengers who caused the problem refused to bend. For all the crew's displeasure, they didn't handle the passengers, the passengers handled them."

Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."

Pros: "Got us here early, smooth ride"

Pros: "New plane, wifi, arrived 27 mins early"

Cons: "Not 2 hour delay leaving."

Pros: "The flight crew were Amazing on both flights. Seating was good on the 1St flight, I got the aisle seat, 2nd flight was little cramped “middle seat” I’m 6’3”. The flight was only and hour so not bad. Overall it was good."
Cons: "About 2more inches in the seating for long legged people taller than 5’8”. I’m 6’3”. So pretty cramped if not in an aisle seat."

Pros: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge."
Cons: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge)."

Pros: "During the flood we had to go around the storm and camping was good to keep us informed of the status"

Pros: "crew is always resilient"
Cons: "Our plane was on time coming into Denver. We ended up changing gates due to another flight. Instructions for changes were not easily understood on the overhead.

Pros: "Very smooth flight"

Pros: "Staff was great. Baggage and service was handled well."

Pros: "Great flight"

Cons: "3hrs late"

Cons: "There was no flight. I was transferred to another airline by a frontier representative. That flight ended up being delayed as well."

Cons: "Charge you for everything!"

Cons: "Bags were lost by multiple passengers."

Cons: "Charged for every little thing"

Cons: "The check-in process didn't work and was confusing. Every time I tried to check a bag and pay the reduced fee, the website returned me to the window asking for username and password again. I could not check-in on line and had to pay full fee for checking my bag. I was frustrated and at the airport there was no consideration for giving me the reduced fee in light of the website malfunctions by the agent checking me in. Also, the steps during the check-in was confusing - trying to sell upgrades etc, instead of just taking you thru the check-in steps."

Cons: "That you have to pay for a carry on, and when I tried to go on line to pay for a carry on I couldn't find where to pay for it so I had to call frontier to pay over the phone"

Pros: "Cheap round trip tickets."
Cons: "Unreasonable delay time. Lost baggage. Mediocre customer service for the lost baggage."

Cons: "I will never ever buy a ticket through Frontier again. Worst airline ever."

Pros: "Nothing"
Cons: "Charging for baggage and not making it clear before buying tickets. Having to wait for baggage."

Cons: "Too much nickle and diming. Website confusing"

Pros: "The crew was exceptional!! It was like booking a comedy club act in addition to the plane ticket. Made the run super enjoyable. Frontier fares would be worth the savings for me if available connections to the cities I need to visit were better & if I could check a bag at a reasonable cost. See my objections in other box."
Cons: "I still cannot get used to the lack of complimentary beverage during the flight - nor the fact that Frontier charges for carry-ons & tries to get me to "buy" a seat assignment when checking in on-line. Very deceptive web site. My principle dissatisfaction with airlines these days is being charged for every item they can possibly scrape an extra penny of profit from. Most people cannot manage a trip without some type of bag. If air fares reflected the savings, then the offset would be worth it - but most often that is not the case."

Pros: "The flights were on time."
Cons: "The seats were in comfortable. They charge for baggage whether you check or carry on. They don't send emails to allow check in by phone or computer if you buy your ticket on the internet. Bag check fees are too expensive. You have to pay for all beverages. When all things are considered, when the tickets cost the same amount, there's no reason to pick frontier."

Pros: "It was quick"
Cons: "The charge for carry on"

Pros: "The airline crew did a good job."
Cons: "First unexpected costs were not revealed at booking, price for the trip does not include your Carry-on bag. If you want to check in early there is a per seat charge otherwise it's assigned seating by them. We stood in line @ the Frontier counter to check baggage for 1 hour!!! It was understaffed and poorly organized. Then it took another half hour to get through TSA; not Frontiers fault. By the time we got to our gate we were already impatient to get it over with. Boarding was slow as many passengers with window seats came on last forcing a constant reshuffling of passengers. While the crew was competent, all the other problems made the flight very mediocre."

Pros: "MCI departure efficient"
Cons: "DIA tarmac delay, unable to get to gate"

Pros: "The steward staff and pilot tried to be comical and entertaining. That was fun."
Cons: "No offers for drink or snacks unless you pay for them. Charged for luggage to check and also charged for carry on. Charged for seats unless you wanted to wait until you got there and received poor seats. Charged for every little thing but couldn't even offer you a drink and a bag of chips. Flights delayed. Never again. I'll go with Delta or Southwest from now on."

Pros: "I paid for a better seat in the stretch seating and it was very comfortable with a lot more leg room."
Cons: "My flight to Kansas City was one hour late in leaving. No information was given to us about updates or why? My return to Denver was over 2 hours late. Once again, no updates or why? Southwest gives you peanuts, crackers and a free soft drink. You have to pay for everything on Frontier At the baggage claim we waited a long time. The information board showed our flight at #3. After a long time a passenger yelled to all of us, "hey, it is down here at a difference place.""

Cons: "Plane was an hour late. Then we waited an hour on the runway after we landed."

Pros: "Nothing"
Cons: "Everything. Very long flight delays, bad customer service, aggressive attitude of flight attendants, uncomfortable seats in the planes and hidden costs every step of the way."

Cons: "I had never flown on Frontier before. I selected Frontier because it offered the least expensive flight. I did not know that to get a seat I had to pay a fee for each leg of the trip. I also was not aware I needed to pay $30 to check a bag. In addition, I was not aware one could not even get water on the plane without paying for it. To top it off, 2 of the three bathrooms on the plane were inoperable."

Pros: "Friendly and couteous"
Cons: "How the seat selection goes, having to pay more to have a different selection"

Pros: "Simple boarding process, friendly crew."
Cons: "Paying for beverages? Ridiculous. I rarely fly Frontier (unless I have to) because they charge for everything."

Pros: "I liked the price that I paid for the ticket!"
Cons: "I didn't like having to pay for the bags checked or carry on, or the seat, soda, snacks, and anything else you might want."

Pros: "I slept on the flight and they only served drinks and cc applications"
Cons: "Took a long time to board and get off the flight. Our luggage took an hour to start coming into baggage claim. The staff barely said hi or bye to anyone or smiled."

Pros: "Its a quick flight"
Cons: "Boarding took longer than norm departing and arrival. They took away reclining seats and any type of entertainment. Not really like it used to be."

Cons: "Ticket counter attendant was rude and threatened me after asking about the carry on policy. A passenger was arrested and escorted off the flight and the turbulence was so bad someone threw up. The crew and pilot made no comment or even acknowledge either incident while boarding or while on the flight. I will never fly on Frontier Airlines again."

Pros: "Flight was on time, actually landed ahead of schedule."
Cons: "Had to wait on tarmac because gate was not ready. Did not know about high bag fees and fees on everything else. Had to wait for an hour after pulling into gate for luggage to get in. Seating very uncomfortable and could not adjust the backs. This was my first time on Frontier, will pay extra to not fly frontier again"

Pros: "Cheap flight"
Cons: "Extra charges for baggage"

Cons: "Uncomfortable seats, drinks aren't complimentary, paying for carry on luggage"

Cons: "Seats. Fees associate with bags. Customer service"

Pros: "I didn't receive a smile or even an acknowledgement from flight attendents. Couldn't hear the safety speech at all. Annunciate and speak clearly would be my suggestion. This person sounded like they had a mouth full of mashed potatoes. I won't fly frontier again even though it used to be my preference. The baggage fee, not even a complimentary drink?? Uninterested staff. Very poor customer service. However, the pilot got us to destination on time and w/out mishap, hence my OK rating. Otherwise super disappointed in crew and staff."

Cons: "Arrived half an hour early but my seat was already sold. Wasn't offered to be put on a different airline and didn't feel like I was cared for as a customer."

Pros: "Flight crew was good once we were able to board."
Cons: "3 hour delay in getting to destination"

Cons: "i didnt realize there would be so many extra fees for baggage and seats... knowing this i would have purchased a different flight."

Pros: "Nothing"
Cons: "Customer service was rude. Seats were ironing boards with pleather covers, we were all especially jammed in. Airline crew was not pleasant. The best thing was when it was over."

Cons: "Being charged $45 to carry on a bag. Ridiculous."

Cons: "Delayed again longer then they said it would be as well, also their reason was "there's no good reason" awful"

Pros: "The flight departed on time and arrived as scheduled."
Cons: "I'm glad that I arrived safely because that is the one thing I can appreciate. The cheap fares equal the quality of the plane. Only 4 rows of 30 have reclining seats. It would be a stretch to say the seats are padded. The clientele is cheaper than the fare with lots of crying babes and impolite guests running to the door as the plane arrives to the gate."

Pros: "The take off and landing were perfect."
Cons: "The seats miserable and the little miniature trays were ridiculous. I didn't realize that you had to ask for water. the charge for carry on was equal to $60.00 and I had only two short trips although they were round trip."

Pros: "The boarding was fine, The flight was good."
Cons: "The baggage fees were ridiculous. especially carry on. And on such a short trip. I feel if you're flying on any airline one carry-on and one checked luggage per passenger should be free. Anything after that then charge for it. Especially for flights shorter than 2 hours. like ours from Denver Co. to Kansas City Mo. Unless you're traveling without any bags I guess it's pretty inexpensive. But that's unrealistic. I'll probably check other airline options as far as baggage. Cause this is a horrible way to treat passengers flying on your Airline."

Pros: "The spirit employees were very helpful when I checked in"

Pros: "They suck so bad!!!"
Cons: "They just suck really bad!!!"

Pros: "smooth"
Cons: "death do not recline"

Pros: "Got the row to myself"
Cons: "Small chairs"

Pros: "Noting"
Cons: "Everything"

Cons: "Why ask for a ratING on food and entertainment that don't exist?"

Pros: "Raise ticket price and don't charge for first suitcase"

Pros: "Nothing"

Pros: "Planes were new and clean."
Cons: "Airport was disorganized. Check in was long and a mess at 8:30 in the evening. Long lines. Staff not helpful. No checkin kiosk to get bag tag. Probably will not fly Spirit again."

Pros: "O"
Cons: "BEFORE YOU GET ON THE PLANE SO MUCH EASIER ON DELTA I WILL NOT BE BACK"

Pros: "Like the convenience of the flights between Las Vegas and Denver. The ratings above you need to have a N/A for non applicable. We all know there's no entertainment. And the food is overpriced ! But"
Cons: "See above answer"

Pros: "Needs more room. Packed like sardines"

Pros: "Good seat, enough room"
Cons: "Cost for food"

Pros: "Nothing"
Cons: "Fees, late arrival"

Cons: "My luggage was lost and I'm without any belongings for myself or my 1 yr old baby!"

Pros: "I liked the bundle prices on drinks."
Cons: "No monitors behind seat headrests or wifi and arm rests became very uncomfortable"

Pros: "Nothing"
Cons: "Everything"

Cons: "Payment for drinks"

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 wonderful, the l8nes wwnt by quickly"

Pros: "No frills or hassles"

Pros: "It was safe and fast"
Cons: "Too many delayed Times and too cold for me. They also have too many fees added to total cost"

Pros: "We didn't crash"
Cons: "Everything else"

Cons: "The baggage charges are ridiculous. Couldn't believe them. Won't be flying on this airlines again soon."

Cons: "Spirit airlines employees are not friendly and difficult to deal with. Were not accommodating"

Pros: "Nothing"
Cons: "Kayak"
