Pros: "Prompt boarding and good directions from the crew"
Cons: "AA cancelled the Dallas flight before this one so they could fill up our flight. This does not seem very considerate of our health during a Pandemic especially with their messaging about social distancing. They also did a very poor job of keeping people patient in the deplaning process. They should have better messaging and a very non threatening way of encouraging passengers to be patient and courteous. Maybe they good offer each passenger a choice some type of goodie like a mint or a chocolate that says "please enjoy this while you wait for others to exit the plane"."

Pros: "Flight departed on time. Good seat pitch in economy. Food and beverages included and tasted good surprisingly. Crew were helpful and efficient. Plenty of entertainment options for film, TV and music."

Cons: "Immediately after all passengers were boarded United discovered the plane had to be replaced. We all had to deplane, wait an hour more for a new A320, and reboard.

Pros: "Nothing"
Cons: "We’re about to take off, had to go back to the gate due to poor inspections, then they had to move us to another plane and couldn’t be less effective. Gave everyone the wrong gate twice, it was ridiculous. Someone at United should hire a six sigma trainer to teach employees about efficiency."

Pros: "Quiet flight and very efficient food and beverage service."

Cons: "Gate agent not very helpful when my wife and I were assigned separate seats."

Pros: "I didn't get dragged of a flight due to overbooking. So that is always a positive."
Cons: "United needs to add more entertainment options to all of their flights. Virgin, JetBlue have done this. Why can't United? You have record profits, invest it in inflight experience."

Cons: "My itinerary had to completely change."

Pros: "Everything was great expect for one thing."
Cons: "I was made to gate check my bag as I was boarding which was fine, yet they wouldn't let me move things around as I had lots of items in the putter pockets and my gloves got lost."

Cons: "Small.plane, nasty sweet snack! Geez are peanuts that much more expensive!?"

Pros: "I liked the boarding process. The staff were nice people too."
Cons: "The plane made a horribly alarming screeching sound before takeoff. WiFi was out. The snacks tasted like stale trail mix from a Fresno gas station."

Pros: "Movies were ok."
Cons: "Openly rude, almost argumentative staff. I was afraid to talk back because the last thing I want is any accusation of bad behavior on an airplane. But if this were a restaurant, the customers would get up and leave without eating. I've never had this experience on China Airlines or Japan Air. I will never use UA again."

Pros: "Good service"

Pros: "Flight was early!"

Pros: "Was impressed w the new plane"
Cons: "Overhead storage a little small"

Pros: "That's it was fast and organized"

Pros: "Kayak e mails on gate changes and such"
Cons: "N/a"

Pros: "I liked the coffee."
Cons: "Flight was delayed by at least 45 minutes, making me miss my connecting flight. After that I had to wait 7 hours for the next available flight. Also the connecting flight was all the way on the other side of the airport. No one at the airport would help with directions to the next boarding area."

Pros: "Very friendly flight attendants & the pilots kept us posted on everything which made me feel extra comfortable!"

Cons: "Delayed departure, changed gate."

Pros: "Everything went smoothly, times were great!"
Cons: "Crew a little snippy.."

Pros: "Nothing"
Cons: "They cancelled my flight the morning of, I was rerouted through a later flight to AA when the United employee couldn't speak enough English to communicate, I misheard 2:30 when she actually said 2:13. Showed up an hour early as I always do at Eugene airport, only to have the gate shut in my face...we'd missed the flight. I then proceeded to get in my car and drive three hours to catch a connecting flight to Phoenix through traffic etc etc....only to arrive in Phoenix 6 hours later than expected. All of my evening business meetings, lost. Thanks United, you always seem to find a new way to screw it up."

Cons: "Take off delay due to catering"

Pros: "Nothing"
Cons: "Everything"

Cons: "Have passengers with no carry on off the plane first."

Cons: "Negative leg room, Hugh bag fees that were not stated in the original purchase"

Pros: "Arrived 30 min early"

Pros: "Low entry fare"
Cons: "Add on fees for everything which is fine if you are aware of them. The low blow was the $8 can of domestic beer."

Pros: "Not much to like."
Cons: "First flight was cancelled due to mechanical issues. Didn't get to SF until the next day - had to sleep in a hotel in Denver of all places. Why? Flight home was delayed 8 hours. Got an incredible price for the ticket of less than $100 round trip but I doubt it was worth it. I would rather have gotten to my destinations on time."

Cons: "I, and many others waited over an hour before the ticket counter was staffed. It opened at the last minute, two hours before the next flight. Some people waited 2 hours. Many grumpy passengers. What saved the experience was the friendlyness of the flight crew."

Pros: "I didn't like anything about traveling with Frontier."
Cons: "Upcharge for Seats, Upcharge for Checked Bags, Upcharge for Carry Ons, Upcharge for Water. They charge you for water. That seems illegal. The flight was delayed, the gate was changed. We had to change gates which means we had to go through security twice. The staff blamed everyone and everything else (even the passengers) for all the issues and took ZERO responsibility for anything. I can't believe they are still in business with this level of customer service. The flight attendants were ghetto too. Making light of a bad situation by saying the worst things possible. Total embarasment transfer. I'll never fly Frontier again and will think twice about booking travel with Kayak."

Pros: "Co-pilot who had to explain to passengers why so many flaws occurred in this flight, she tried to be humorous."
Cons: "Flight 1884 out of SFO was doomed from the beginning starting with a notice (thanks Kayak) via email that the flight would be 1 hour late. Then, the Departure board at the airport totally dropped the flight, Then (again thru Kayak) I read that the flight would NOT board in terminal 1, Gate 21, Domestic terminal, but ar gate A3 in the International terminal. We all had to exit domestic and go to international and again through TSA. Then the flight departed another 30 minutes late finally over 2 hours LATE! Upon arrival at Phoenix the plane taxied too far away from the exit ramp-another 40 minutes before we could depart. It was an awful flight experience. Did they offer a free soda or anything for inconvenience we experienced-NOT A THING!"

Cons: "I paid so much for a seat when the plane was empty and people were shuffling around anyway. I also paid $40 for a carry-on and was then told that I didn't have to because my bad was so small. In addition, baggages are non-refundable. I won't be taking Frontier again. :("

Pros: "Easy boarding with the zone system."
Cons: "No space at all in seats and tiny tiny tray table....to tight, way to crammed in."

Pros: "How friendly the pilot and crew were."
Cons: "Paying for carry on baggage."

Pros: "Quick boarding! ! Love getting on fast and flying out."
Cons: "Paying for a soda is crazy! Increase everyone's ticket by $1 and offer cover, tea or soda. It would still make you money with less paperwork."

Pros: "leg room was OK."
Cons: "2 hours late. kiosks were not open for check in until just before the flight, had to rush to security and hope I could get through to catch the flight, no one enforced the rules on the size of carry on, people were taking on many bags, and big bags, and no one said anything. Had to pay for ALL snacks..."

Pros: "Easy to check in. Everyone very helpful and friendly."
Cons: "No criticisms"

Cons: "Hidden fees for carry-on bags is RIDICULOUS! Original gate was changed to the international terminal at SFO which meant getting a tram and going through a long security line again. When we landed in PHX, there was no available gate so we waited another 35 minutes. Seats are very uncomfortable and DO NOT recline at all. They also charge for soft drinks. Low budget...poor customer service...numerous delays...hidden fees...steer clear!"

Pros: "I met a cute guy! Lol"
Cons: "They delayed our flight 3 hours! And charge for carry ons! Who does that. I paid $100 for these tickets and my $75 American airline ticket gave me a free carry on."

Pros: "Friendly crew, liked the Happy Hour special..offset the cost of no complimentary beverage"
Cons: "Surprised about the price of luggage, my seat and front pocket was dirty with stuck gum"

Pros: "Nothing"
Cons: "Delays! Overcharge on baggage Comfort sucks"

Pros: "Nothing"
Cons: "Plane cancelled, no help from frontier customer service, will never fly on this airline again"

Pros: "So...i will never fly frontier again. Charging $40 for a carry on is outrageous. Also, i had to pay $17 to check in and get a seat. In my opinion, this is the worst airline I've ever flown. I'd rather book a flight that was (40+40+17+17) more expensive so i knew what i was getting. Than fly this airline again. On plane the service was great. I just felt like i was duped into buying a more expensive ticket than was proposed. I will never fly frontier again ( and i tell my friends that too)."

Pros: "I got to my destination on time."
Cons: "it's not worth cheap ticket if your going to charge an arm and leg for everything else."

Pros: "polite and friendly crew"
Cons: "Extra costs for seats, soda/drinks (not water) and carry on luggage on one flight from SFO to PHX I ordered a water, but it never came Same flight SFO to PHX was delayed 2 hours for unknown reason Seats were firm and trays were tiny"

Cons: "Paying for my seat - paying for my coffee - paying for my luggage - not the bargain I thought it was - I could have easily taken another airline with more convenient departure and arrival spots and SAVED money!"

Cons: "The baggage fees are ridiculous. Your bags should never cost more than you (the customer). You try and check in online and they want to charge you more to pick a seat. The seats are tight. The tray table is the same size as my cell phone. (The smallest I have ever seen). Airtravel has reached an all time low with Frontier. I was glad my return flight was on SWA. SWA was cheaper fare, has better seats and a better table, and no baggage fee."

Cons: "There was an additional charge for everything! In total, my seat and bag cost more than the ticket. They were charging 2.99 for club soda."

Cons: "The fare as advertised was misleading. I did not realize until after the flight was booked that I would have to pay an additional fee to select ANY seat. I would have much preferred that the basic seat price be included in the fare. While I anticipate baggage fees at this point, I was taken aback that carry-ons were more than checked luggage. As for the additional fee for a soda...is that really necessary? Not planning to fly Frontier in the future."

Pros: "The only thing I liked was getting to and from my destination safely."
Cons: "I didn't like getting delayed for over 2 hours. Especially when the frontier app said the flight was on time. Then I show up to the airport and find out the flight is delayed over two hours. Then when we finally get to board, we get taken off the plane for more of a delay!..almost 3 hrs in delays is horrible. Not to mention the hidden fees of a carry on?? Are you kidding me? I hope I never have to fly frontier again!"

Pros: "Landings were very smooth."
Cons: "1. Charged $40 for carry-on (each way) 2. Charged $2 for tea. 3. Charged $20 to choose my seat (each way). 4. Flight was 90 minutes late (on a 2 hour flight), no explanation given. 5. Flight delayed another hour due to mechanical problems, no compensation offered, tea still $2."

Pros: "Great leg room, clean, on time and great staff"
Cons: "Everything was great."

Pros: "Everyone was friendly, will fly again soon to San Fran."

Cons: "In San Francisco we were not charged for our carry-on luggage, so we did not purchase the outrageous $40 fee prior to our Phoenix departure. We were stopped at the gate and told we had to pay for our carry-on luggage and because we didn't pay the fee in advance we were charged $60 for our carry-on. Person at the gate said "I can't help what they do or don't do in San Francisco. Get it together Frontier. We will NEVER fly Frontier again!"

Cons: "Angry staff, uncomfortable seating, and the poor scheduling updates."

Pros: "The crew was as helpful as possible, very kind and clearly as frustrated with the situation as we were, and did their best to make sure the rest of our flight was comfortable."
Cons: "My flight was delayed for three hours. We were loaded on to the plane, then told it would be another hour, got off the plane, got back on, and it was still another 20 minutes until we started moving. It was tiring, frustrating, and caused a lot of issues with my ride in Phoenix. I do understand, however, that many of the issues were unavoidable, such as mechanical problems and missing mechanics, but it was frustrating nevertheless."

Cons: "I had a pretty unpleasant experience with Frontier on 12/21/15. Rain in San Francisco caused flight delays. Go figure. Frontier kept us waiting for six hours then cancelled the flight. They were rude; they didn't help their customers, including families with kids, get on other airlines; said they would try to getpeople out of SFO in the next couple days! When I realized I would not get to the wedding I was trying to attend, they siad they wouldn't refund my money' When I insistedon a refund they then said there would be a $19.99 cancellation fee. Eventually, they agreed on a refund. Pretty poor way to run a business. On the other hand, when I needed to cancel my Enterprise car rental, I was able to do it in less than two minutes over the phone - no hassle."

Pros: "The crew was fine."
Cons: "It is incredibly dishonest to not include the 40$ fee to carry on any bag, and 13-20$ fee to choose a seat, bringing up a 60$ per flight leg additional cost. That means roundtrip tickets can easily be 100$ more expensive than listed, making other, more reputable airlines actually cheaper. Not to mention they do not take electronic tickets like every other airline, and when the flight was delayed, I went to have my ticket printed and no one was staffing the desk and no automated kiosks were available. I managed to flag someone down and they wanted to refuse to print me one because "my flight was listed as earlier" despite me being emailed by them that the flight was delayed. I eventually got to my destination, but I will never book a flight with them again. Let's not even mention charging for water, the plastic seats on the plane, etc. Terrible airline."

Cons: "Lots of delays"

Pros: "I was easliy checked in"
Cons: "It was more then an hr late The plabe shook all the ride long It felt terribly unstable"

Pros: "Nothing"
Cons: "Everything"

Cons: "Baggage ripped off.. Im never riding this plane ever.."

Pros: "Nothing... Charging for baggage overshadowed everything I canceled the return and Booked on southwest. This is an dishonest, tricky, unethical company."

Pros: "The smooth flight"

Pros: "Staff was friendly, aircraft was comfortable, there was no line at check-in desk."
Cons: "Baggage policies are very expensive and inconsistent with other airlines."

Pros: "Friendly staff"
Cons: "Hidden costs, uncomfortable seats, little space. Not worth the cheap tickets when you then have to pay for a seat and high prices for baggage. It comes out the same as other airlines."

Pros: "The flight wasnt worse than those of other, more expensive carriers. Very competitive prices."
Cons: "The flight was delayed by 40 minutes. The flight crew was sort of friendly, but not as warm and welcoming as on other airlines."

Pros: "Not much"
Cons: "I did not like the carry on fees of $45 per bag. Flight 1365 had some rude stewardess who in my opinion has something against Asian people. The plane landed in the wrong terminal. Taxi'ing took a long time. the seats aren't adjustable ."

Cons: "No drinks like coffee provided free"

Pros: "The flight itself was okay, except there was a 1.99 charge for a can of soda. But what really made the trip miserable for me is that I was charged 60 dollars at the gate to carry on my small bag which would not fit under my seat but did fit in the overhead space. Nowhere that I saw when I bought this ticket did I see on the website that I would be charged for carry-on luggage. When I got my boarding pass, the guy asked if I wanted to check my bag and I said I would carry it on. We agreed the size was okay. He did not mention to me at that counter when I was getting a boarding pass and we were talking about the bag that there would be a carry on charge. I didn't learn about it until I was at the gate and couldn't do anything about it. If I had been told at the counter, it would have only been 45 dollars and 30 to check it which I would have done. On the plane - thinking about it - I realized he must have been told by the company not to mention the charge so that I would have to pay SIXTY DOLLARS to carry my bag on and the company would get maximum amount of money from me.. That is a complete scam and I feel really ripped off. Because of that experience, I WILL NEVER FLY FRONTIER AGAIN! and I am telling all my friends to stay away from Frontier as well."

Pros: "Nothing"
Cons: "Everything"

Pros: "It was only 15 minutes late. Security and check in were easy to navigate"
Cons: "it was late and we missed the shuttle in Phoeniz"
