Cons: "Didn't hapen"

Pros: "Delayed. Bagage mis-rerouted."
Cons: "Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too.

Pros: "Everyone was really nice, and there was a decent amount of leg room etc."
Cons: "I honestly can't say that I have any complaints about it. Thank you. :)"

Cons: "Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had."

Pros: "Great staff, pleasant flight, nice options on the screen to choose from, etc."

Cons: "We were delayed in Chicago due to weather coming home from Europe. We were not allowed to use the business class lounge even though we paid for business class tix. My family is still sitting in the airport waiting on their flight to dallas. We have been up now for over 24 hours. We should be allowed to be someplace comfortable for the price of the business class tickets. poor form on Lufthansa’s part."

Cons: "Delays"

Pros: "Fast boarding and friendly staff."

Pros: "We had no difficulties and the crew was friendly and helpful."

Cons: "internet & movies intermittently worked"

Pros: "Everyone was very respectful"
Cons: "Sight delay and having to pay for internet"

Cons: "This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane. When my flight was canceled initially no one informed me that my return ticket would be canceled which I specifically asked about. I hope never to fly united again. The day to day staff at ohare and on flight were good and courteous."

Cons: "The boarding process is horrible. You have to stand in lines that disrupt the other people trying to navigate through the airport."

Pros: "The boarding and check-in process was quick and seamless. The crew was attentive, friendly, and informative. Ohare airport has Garters popcorn!!!!"
Cons: "Seating was a little cramped, even for a small guy like me, and the only way to watch anything on the small screens provided on seats in front of you, is to pay. Honestly, I know that everything is about the bottom line, but you can at least provide 1 free movie or Channel and charge for optional premium material."

Pros: "The crew was polite and offered an extra six ounces of water in addition to the usual beverage service. The flight departed and arrived on time, which is a rarity when dealing with ORD."
Cons: "The cabin was near 80 degrees Fahrenheit for about 30 minutes of boarding. During the boarding process and taxiing, the DirecTV add ran theee times. The commercial was annoying and loud. Once would be enough."

Pros: "Was able to fly standby and get home earlier. Crew was nice and friendly."
Cons: "Slept most of the way, but this plane didn't have television screens, so limited entertainment options."

Pros: "Very windy decent into denver but pilots and crew were great."

Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"

Pros: "The fact that priceline said there was nothing they could do."
Cons: "The fact that my pregnant wife and i were stranded in la guardia airlort and had to shovel out 800 dollars for last minute one way flights."

Pros: "Friendly crew."
Cons: "Passengers are stowing personal items/multiple bags in the overhead bins. This is an ongoing problem that needs attention. Armrest protocol should be made explicit. My in-flight entertainment control was covered by the passenger next to me the entire flight."

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

Cons: "The flight delay and my missed / delayed luggage."

Pros: "."
Cons: "Each flight we booked for our holidays had issues. 4 seperate flights and not one which we were please with. Late departures on syper hot planes, staff not present for boarding planes in time, complications with paperwork pertainig to the plane delaying flight/computer glitches. Not a good experience. We paid nearly tripple for our flights for the convenience of not having to drive to denver....we will never do that again"

Pros: "Did not make our flight to dickinson sitting in line in denver to make new flight. Only one flies into dickinson on sun and it's a late one. Will have to fly to different city."

Pros: "It was Great Thank you"

Cons: "Delayed, missed connector flight to billings had to spend night in airport. Flight delayed 2hours to billings the next day. Worst flying experience ever will never fly United again!"

Pros: "Flight ahead of schedule. Friendly crew - got a full can of soda!! Good to see small snack reintroduced."
Cons: "Felt very cramped as was a full flight. No personal entertainment available, unless you paid for DirecTV."

Cons: "I missed my flight to San Diego from a connecting flight by a few minutes. Now I have to sit in the airport for over three hours waiting for my next flight.. not to mention it's my bday. Thanks United."

Cons: "Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again."

Cons: "45 minutes late taking off"

Pros: "New, clean United planes! Happy crew! Snacks!"

Cons: "My boarding pass was not scanning which was holding up the line. A second person came over to approve me getting on the plane. That person made me check the size of my carry on bag, which had gotten bigger from some things I purchased in the airport but was just a touch too large for their sizer. She attempted to check the bag meaning I wouldn't have it until my final destination, which I was NOT ok with for two reasons. One was i had a 3 hour layover after this flight and needed work materials inside. The second was i was on a time crunch to get my ride at my final destination and was only traveling with carry on. She was very rude and insitant on it fitting inside the sizer as she stood over me with the tag to check my bag. I managed to take some things out that I moved into my backpack, which meant I had to awkwardly carry my blanket and travel pillow onto the plane. The most frustrating part was when I got on the plane, it was oversized top carryon bins, so the extra inch my bag grew would have been fine. Because of the time it took me to rearrange, i was the last one on the plane and all the bins had been filled with tiny second bags, but a few people on the plane had seen what happened and they rearranged a space for me. Also my video screen was broken and everyone else's worked. And there were two screaming babies around me the whole flight, but that is no one's fault."

Pros: "I liked arriving home in a timely fashion."
Cons: "The first gate agent responding flatly, "I have NO idea." to a gate change question. OR the Mother Superior flight attendants that couldn't wait to point and nag about seat backs and tray tables. I wonder if either of the women noticed they were talking to someone who wasnt't an English speaker? United needs to fly Southwest to learn the right way to do things."

Pros: "Crew was great and the boarding staff was very friendly."
Cons: "Flight was delayed"

Pros: "The flight attendants were all super kind."

Cons: "United is a horrible excuse for a company. 3 mechanical delays ultmately causing us to miss a wedding which was the reason for our trip. A 5 hour delay out and an overnight delay in the way home. We slept on the floor in the airport- one thing for us but disgusting to see United allowed this for elderly and families with toddlers and babies. The third mechanical delay occurred after we were finally bored and on the runway and they wouldn't let us deplane. Never have I been so terrified to fly."

Pros: "The flight is comfortable and the no hidden fees."

Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."

Pros: "1st time I ever watched the safety/instructional video. Great job because it is important stuff and I saw others paying attention as well!"

Cons: "When the guy in front of me reclined his seat, there was no leg room. Today, I literally have bruises on my knees....ridiculous '"

Cons: "Not much. Brand new 737-800 that was the most cramped uncomfortable cabin/seats I've ever been in next to a commuter flight. Middle seat in the last row no recline didn't help. And my knees were up against the seat in front of me all the way. Was battling back cramps and spasms. Felt like a sardine. And we got no beverage service"

Pros: "Nothing"
Cons: "I didn't like that I missed this flight because your first one was late"

Cons: "The boarding process was horrible. The flight was running late there was no communication until people started screaming at the person behind the counter tell us what the heck is going on. Then they made us walk at least a mile to the plane."

Pros: "I really understood that we were all going to have a bad experience and at least they were happy and perky"
Cons: "No water no drinks no food not even for sale. No internet and the seats were horrible never again will I fly frontier airlines don't care. They were just metal chairs with a tiny bit of padding"

Pros: "Boarding was quick and painless."
Cons: "Better seating arrangements. They announced that we can change boarding passes to new seating but only after scanning our boarding passes. Then said No way because we already boarded."

Pros: "We were on time"
Cons: "It was just fine"

Cons: "They don’t care if you have a medical emergency"

Cons: "Very uncomfortable and I don’t usually care about comfort. I understand the upcharge for everything to create affordable flights to individuals, but with a family I am better off buying a more expensive flight that has some inclusions as the price evens out."

Pros: "Flight attendants so nice!"
Cons: "Crying babies"

Pros: "Nothing"
Cons: "Delays, gate changes, lack of notification, last minute changes."

Pros: "It was a safe flight"
Cons: "The flight was initially delayed 1 hour early in the day and notification was sent out. The flight was delayed again later in the day and the notification was sent out but not so promptly. An announcement was made at the gate that the flight was further delayed because the flight attendants had to clear customs. The flight attendants showed up about 30 minutes later, carrying bags of food from the resurants in the airport. I understand the flight attendants need to eat, but our flight was delayed prior to their landing and this added an additional delay. In total my flight was delayed about 2.5 hours."

Pros: "No one at chi O’Hare knows Frontier is now at international departures so cab drivers ride share drops off at wrong terminal. International terminal negates tsa pre"
Cons: "See above"

Pros: "friendly staff on flight but before boarding they were not friendly"

Cons: "The screen at the also gate did not reflect this was headed to Orlando or that it was a frontier flight causing unnecessary confusion. Unsure why no signage was used."

Pros: "seating boarding accommodations for children"
Cons: "Very Costly over other flights this time of year"

Pros: "I FIND FRONTIER EXELENT FOR TRAVEL IF YOU DO NOT CARRY LAUGAGE . ... STILL GIVEN EXELENT"
Cons: "charge for small carry LAUGAGE. . in chicago check in not very friendly. ... prev experince .. this time was juts right . i Recomend this air line .. smooth flight and Fast when i said Fast.... in time or better. .."

Pros: "Nothing."
Cons: "Frontier sucks. Long weights, terrible customer service. I will never book through a 3rd party ever again."

Pros: "Price"
Cons: "No food or drink"

Pros: "On time"
Cons: "Not a very friendly staff... Got the feeling they might be overworked. One male attendant didnt crack a smile on the entire trip."

Pros: "Nothing"
Cons: "All the the hidden fees from the baggage to seat selection. No snacks or drinks were provided unless bought individually and the cost for the flight wasn't any cheaper than our flight up on United, which included everything at no additional charge. The customer service was awful and though we arrived at the airport over an hour and a half early, we almost missed our flight because checking in a bag was chaos (despite having checked in online the day before). There were no forms of entertainment on the flight, not even airline magazines, which made for a very tedious 2.5 hour flight in less than relaxing seats."

Pros: "The pilot flew the plane smoother than butter"
Cons: "The flight attendants we're more interested in socializing than taking care of the passengers. If you asked for anything it was a major inconvenience. They only take cards not cash for ALL drinks including water. No entertainment and no complementary snacks."

Pros: "Great crew. Inexpensive flight."
Cons: "I have no dislikes."

Pros: "Very comfortable ride and spacious"

Pros: "Bag charged"

Pros: "I admit that paying for carry-on bags, and paying extra for an assigned seat was irritating, but it still cost considerably less than any other airline. The plane was clean and looked new; the crew friendly and helpful."
Cons: "Nothing. I knew upfront that this was a "no frills" airline and did not expect all the niceties."

Pros: "The flight was on time"
Cons: "The additional fees for things like carry on baggage is makes the price misleading"

Cons: "Because of Hurricane Matthew and the forecast that it might return to Orlando, FL, my family cancelled our vacation to Disney World, as we didn't want to risk being stuck during a hurricane. When I called to see if I could get a credit for the flight, so I could fly later, I was told NO. I was given the option of rebooking the flight by the end of October or I would loose the cost of the ticket or have to pay a $100 change fee. Frontier refused to waive the fee and I couldn't rebook by October because I am a college student and won't be on break and off work again for a few months. No care for a customer under an extreme weather situation. Buyer beware...a cheap ticket is no consolation when you loose your money. I will avoid flying with them. LOST CUSTOMER!!!"

Pros: "No delays, soft landing, flight attendants were very courteous, landed early each flight. I heard all these horror stories & I actually had a good experience."
Cons: "Seats were not that comfortable."

Pros: "Good bare-bones airline - low price if you don't need carry-on or check luggage, don't need reclining seats, don't mind middle seats, don't want any snacks, etc."
Cons: "No participation in TSA Pre-Check"

Cons: "Lugage took forever & no foood or drinks"

Pros: "I liked the staff. They were very friendly. That is all."
Cons: "The check in process was a disaster. I had boarding pass on my phone, but had to print it. Stood in line for that. Then had to check in my bag, stood in line for that. Then dropped it off to TSA stood in line for that. Then through security, stood in line. They need to get their process more fluid. Stood in all yhose lines at 3:45am too. They need to tell people as well youll be paying more if you dont check in 24hrs in advance. Ill just stick to my united and jet blue."

Pros: "Crew was great!!"
Cons: "Didn't like having to pay extra for an extra bag!"

Pros: "The tate"
Cons: "Paying for bags"

Pros: "Crew were arguing with passengers over seating arrangements and when it came time to throw out garbage at the end they completely ignored half of the rows. Even after the lady next to me yelling to get their attention."
Cons: "See above."

Pros: "Original ticket price"
Cons: "Extra fees for CARRY-ON BAG. No in flight snack unless we paid for it. They were pushing their credit card on to people"

Cons: "This had to be the worst flight ever...never heard of you having to pay for seating?"

Pros: "Nice, new plane."
Cons: "Small trays."

Cons: "Cabin was pretty dirty and not well managed."

Cons: "Check-in took 45 minutes, and then I waited one hour and fifteen minutes in security. I missed my flight completely, and when I asked for a refund or credit it was denied."

Pros: "Great prices and way better flight experience than I was expecting after reading other reviews. Seats don't recline but are still comfortable."
Cons: "Flight was delayed and no updates were given. Upon arrival, our checked bags took an hour to get to the carousel. Again, no updates at all."

Cons: "Lots of screaming children, but I had to fly to Orlando."

Cons: "They had me get off the plane during layover in Chicago and were less than polite when reboarding, even with my ticket. The seats had no passing to them. The cost of snacks on the flight were high."

Pros: "Boarding wasn't a problem. The flight crew was okay."
Cons: "Given that plane tickets are cheap, there are additional fees which hikes the price. You'll be better off paying for a flight through a different carrier because it'll come out to the same price."

Cons: "Not Pleasing flight experience. Replace airplanes!"

Pros: "The Airline. Should improve on waiting. time. The flight was delayed by 3hours. This is not due to weather problem , but problem from the airline."

Pros: "Polite servers Almost on time"
Cons: "Cramped No food or drink Nickle and diming costs; very poor (seat, carry on)"

Pros: "The crew."
Cons: "The crew was fine. At no time was I made aware during my booking that I would be charged for a carry on and or checked bag. The total cost added $205 each way for 4 passengers to my flight. I feel completely mislead. Customers also had to pay for water on the flight which was ludicrous. The cost of baggage went up ten dollars from what I was quoted when called customer service to inquire about the prices on preselected seat assignments the day before departure. The seats do not recline and are very uncomfortable. The flight was delayed by five hours and no food vouchers offered. I would not fly frontier again nor recommend to anyone."

Pros: "on time .. smooth flight ..nice plane... good price fligths ..clean plane ...i recomend this air line"
Cons: "have to pay for my pet more that my fligth price...one baggage and had to pay for it overall pay more for this trip .. bad snack and pay higth price even for wather .... ... overall still recomend had flight several air lines had this a good experinses over all"

Cons: "Nothing."

Pros: "Perfect landing in difficult winds"

Pros: "Very cute FA"

Pros: "I've had good luck with a few frontier flights. They're cheaper, and they get you there."
Cons: "If your flight gets cancelled due to weather, they won't work with you. They offered to put me on the next flight - 5 days later. Ridiculous. They offered to get me on another flight the next day - to a different destination - with a $600 up charge per ticket (original ticket price $200). Absurd. Most major airlines get you there the next day, or get you on another airline if they must. Frontier and spirit don't. They'll offer you a refund and tell you to get lost."
