Pros: "Virgin America"

Pros: "Clean nice plane. Free WiFi Free movies. Comfortable seats. Great staff"

Pros: "Seemed to be more legroom and overhead bin space. Fruit and cheese platter was great, esp. for the price. I was impressed with the entertainment options (tablet rentals for less than $10, and some free options with own device). Crew wasn't great, but good enough."

Cons: "Take off and landing at exact time"

Pros: "Everyone is so helpful and cheery"

Pros: "The crew was friendly and attentive"

The staff were friendly, they boarded is early so we could depart early and have a better chance of fighting the head winds. Overall, it was a pleasant trip."

Pros: "Attendants were welcoming, attentive and extremely nice. They all made flying with a 2 year old toddler an incredible experience. Thank you ladies!"

Pros: "Got there safely and on time. The staff was friendly."
Cons: "I'm tired of being crammed into small and uncomfortable seats. It seems comfort is only for people who can afford it. Headrests were non-existent. I'm not extraordinarily tall but the seat stopped just above my neck and felt like a hard, sharp surface rather than something soft and padded. And, of course, there's not enough leg room. Especially once the person in front of you leans back. I don't mean to sound petty but it felt like the airline was more worried about maximizing profits at the expense of their guest's comfort."

Pros: "Flight went smoothly. No major delays or disruptions."

Pros: "Left on time, arrived slightly ahead of schedule. Boarding was smooth. Plane wasn't crowded this flight so had adequate overhead luggage space. Legroom OK. Typical coke and a cookie for food unless you pay for more."

Pros: "Crew was very friendly and helpful seats and movie were awesome!!!"

Pros: "Loved the plane, people and timeliness"

Pros: "Actual flight"

Cons: "There was wifi onboard and it was advertised that we could connect and use iMessage, whatsApp and Facebook messenger free of charge but I wasn't able to do so on this flight. I didn't ask about it but this would be an excellent amenity to keep in touch with the people on the ground"

Pros: "Hey, domestic U.S. flights aren't all bad! I was pleasantly surprised by the kind service and amenities on this Delta flight. There's a plethora of free movies to watch, and the crew continually checked on us to make sure we were hydrated. I think Delta may become my new prefered carrier for domestic flights."

Pros: "The crew was so friendly and helpful and nice. Love the whole online entertainment thing that AA does now."
Cons: "There was an awful flight delay and the reschduling options sucked at first. Once that got sorted to my liking, however, everything else was perfect"

Cons: "3 hr delay and had to change gates"

Pros: "The crew was attentive and helpful."
Cons: "Our layover was originally supposed to be an hour and a half in Phoenix. As we were boarding the plane from Austin to Phoenix, we got a notification that our layover had been delayed an additional 5 hours due to construction at SFO. I’d have appreciated more of a heads up than as I’m boarding."

Cons: "Stale mini pretzels are not appetizing. There are much better inexpensive alternatives. Yuck."

Pros: "Nothing was better than standard"
Cons: "It felt like the staff had instructoions not to smile not even once. The food was beyond terrible. I’m not asking for hot bread like other airlines do, but at least serve it at room temperature instead of super frozen. Same for the butter. The continental breakfast had nothing continental about it"

Pros: "That we didn’t crash"
Cons: "No food offered. Premium seating that I paid for was so narrow there was no way I could sit next to the person next to me and not have their elbows on me."

Cons: "Limited legroom is a problem. Otherwise, the flight was fine."

Pros: "Great service and sweet attendants"
Cons: "Person next to me was a little large and it was uncomfortable."

Cons: "Delayed for mechanical."

Pros: "I loved the attitude and helpful approach of the female flight attendant working the AA gate for the flight I took from DFW to COS last night (6/13). Truthfully, it was almost like I was back with Southwest. She was kind, calm, polite, efficient, and capable. Very rare in my experience with American Airlines yesterday. Interacting with her was refreshing."
Cons: "Getting home to Colorado Springs at 11:30 PM, taxiing for 15-20 minutes, and then waiting another 20-30 for checked luggage! Never have I waited that long during and after a Southwest flight! AA could truly learn something from their more modest counterpart. I have all but decided to resume my drives to Denver every other week rather than risk more and more time and poor experiences with AA flying in-and-out of Colorado Springs."

Cons: "."

Pros: "Great service"

Cons: "Wanted more food. Haha!!"

Cons: "No carbs free meals."

Pros: "Smooth ride, easy security"

Pros: "The boarding process was easy and the crew was great."
Cons: "Other passengers were annoying. One guy was listening to a baseball game on his phone at full volume on the plane during boarding. Another kept hitting the back of my seat playing a game on the entertainment system. And a flight attendant let a guy stay on his phone, while we taxied for takeoff, having the douchiest conversation in history."

Pros: "Friendly flight attendant and arrival earlier than expected"
Cons: "There was nothing not to like. We took off on time, had no turbulence, friendly service and landed early."

Pros: "easy on and easy off. ontime."
Cons: "a little more room between people and more padding in the seats. also delta used to have a screen in each seat and you could see where you were and how far you have gone and so on. could also see more and music."

Cons: "Very full, not super comfortable"

Pros: "It's just like very other airlines."

Pros: "We didn't crash."
Cons: "No safety briefing for infants, rude gate staff, primitive fleet, terrible customer service at all levels."

Pros: "Quick boarding to make up for a late flight arrival."

Pros: "Airport expansion"
Cons: "Due to construction traffic is a problem but still manageable"

Pros: "I like the movie selection"
Cons: "The landing was horrible like slamming on the brakes in traffic. Also when I bought the ticket from Alaska Airlibes on kayak I had bought it at a higher price specifically for that. There was an American Airlines ticket that was cheaper but I opted to pay more because I thought I was flying on Alaska not American. I was very disappointed to see that I was actually flying on American once I was pro ting my ticket and after purchase and "no refund" message. I was very upset about that!"

Pros: "The stewardess/flight crew were awesome."
Cons: "Airport staff, tight seats and boarding process."

Pros: "wifi was great"

Pros: "Infrastructure"
Cons: "Staff behaviour"

Cons: "There was no food offered. The stewardess was not happy to be at work."

Pros: "Staff was wonderful."

Pros: "Arrived. Crew was nice."

Cons: "The 20 minute wait before we could dock at the gate An annoying air vent making an intermittent noise... Something broken obviously"

Pros: "I did not like any of it."
Cons: "We couldn't hear any of the group calling. There were so many different reward members that by the time group B was called I had to check in my baggage. I was not able to pick another seat during ticketing. When I fly for business I generally have a carry on so I can quickly catch my ride however dour to check in of my baggage I had to wait another 30 min before I received my baggage. Air hostess were not very friendly or helpful."

Pros: "fly was on time"
Cons: "food"

Pros: "The flight was on time, and the crew was friendly."
Cons: "The boarding was very disorganized and took a long time, and there was no silverware on board, which I needed."

Cons: "I paid $40 extra to select a seat and the seat was a middle seat and very uncomfortable and a rip off."

Pros: "Nothing"
Cons: "Terrible customer service, multiple flight cancellations"

Cons: "Apparently my seat change did not go through because I was still stuck in the last row near the bathrooms. I must say, the fecal aroma really complemented the on set nausea that was triggered by the turbulence. Every time I thought I was gona drift off to sleep I was rudely awakened by the constant "thwacking" of the bathroom doors. The family next to me was nice enough but they did have a toddler who was very loud and unhappy and the tantrums followed. I have been a server for 14 years and generally can brush annoyances off like this but this was by far the worst flight I have been on."

Cons: "Headphones should be provided in flights"

Cons: "Got cancelled"

Pros: "I fell asleep on the trip so that was nice."
Cons: "The seats are pretty uncomfortable for tall people."

Pros: "Flight was packed in like sardines. Seat was uncomfortable"
Cons: "Have passengers sir at every other seat."

Pros: "The other people flying next to me"
Cons: "The stews attitude"

Pros: "I liked the free in ight movies which makes a 5 hr plane ride a a lot more enjoyable. Having 2 rounds of free beverages was also what I liked. The seats are comfortable, plenty of leg room, love that there are plug/ports to charge you electronic devices."
Cons: "What could have been better especially on a 5hr flight to Honolulu would be free wifi, free meals, if not free meals then 2 rounds of snacks, and I know it's out of the airlines control, but families with their screaming babies who's parents leave the tray down to keep their toddler entertained so she could kick it up and down through out the flight. I feel the airlines should place families with babies and toddlers together on a portion of the plane."

Cons: "Took a long time to board, we were about 10 min late to take off"

Pros: "The counter staff employee was kind enough to find seats next to one another for my partner and I."
Cons: "More snack options."

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"

Cons: "Crowded planes."

Pros: "Crew was pleasant and just plain awesome. Boarding process at Austin was very good. Flight was about 25 minutes early into Denver."
Cons: "Denver airport with all the construction is pretty disappointing. Hard to navigate. They need to hire someone to come up with easier way finders for people to see. Also parking is HORRIBLE. Long term and all the public and private companies offering service and to me not one of them does it well."

Pros: "We were upgraded to 1st. Ontime departure and arrival."

Pros: "Over all flight was good.."
Cons: "Our plane was delayed 4 hours ..I waited at the Austin Airport all day before boarding plane coming from the Atlanta airport due to the outage ..noone was informed of the delay while waiting for boarding. I had missed my original flight and was bumped to a later flight which turned into waiting 8 hours to board ..so, I really was frustrated."

Pros: "Aside from the turbulence the ride was fine."
Cons: "We got stuck for an hour on the tarmac in Denver, completely ruining the transfer process and I got stuck overnight in Denver."

Pros: "I like that since the fight wasn't full, and I didn't know until after I bought my ticket on kayak that I couldn't change seats. The crew allowed me and my friend to sit together."
Cons: "That the window seat armrest doesn't raise to allow more room that's available."

Pros: "Prompt departure"
Cons: "The weather in denver"

Pros: "It was dope."
Cons: "Nuttin"

Pros: "Amazing staff...they went above and beyond during a particularly bump flight! Even brought out pilot wings for all the nervous kiddos...haven't seen those handed out for years!"

Pros: "On time"

Pros: "Drinks and snacks were good. Flight was on time."
Cons: "Flight crew was a little noisy."

Pros: "Not as delayed as the other United flights. Could have been worse!"
Cons: "Gate changed since earlier flight scheduled to depart at 1:30 for San Francisco was still waiting on their plane while we were ready to board at 7:20. Told to go to a different gate. That gate was for Denver but an earlier flight, too. Finally the third gate change was for the correct flight number. Lack of good communication left us and many others scrambling to find where to go."

Cons: "Had to deboard after an hour on the plane. Waited another hour for next flight."

Cons: "Our flight departure time was changed and no one contacted us."

Pros: "Had a window seat that allowed me to sleep"

Pros: "Coming home"

Cons: "No snacks...free"

Pros: "Why's is there to like!!!?"
Cons: "No blanket.. No pllow"

Pros: "Everything was fine"

Pros: "Fantastic service"

Pros: "Boarded on time and landed on time."

Pros: "Telling everyone not to fly United. Thank God United employs competent crew for their planes, please consider doing the same at corporate."
Cons: "Being treated like cattle. Terrible customer service. Not feeding or providing accommodations for the elderly, children, families, and all passengers- regardless of lying about mechanical issues."

Pros: "Basically good, except for delay."

Cons: "Return trip had small planes"

Pros: "This airline is better than most of the others."

Pros: "The staff was very helpful"
Cons: "Turbulence was horrid. Had to re route the landing causing me to miss my connecting flight. united had no other options for 23 hours. Therefore I chose to return to my starting destination. I still had to spend the night at the airport, and missed a 10 hour day of work due to no other flight options. All I received was a verbal apology. Glad I paid for a flight to a one night stay at Denver airport and back."

Pros: "Love junction airport"
Cons: "DIA is always nice and kayak was a great service and price."

Cons: "The fact that the tv is on constantly without the option to turn it off is annoying. The viewing length to passenger is too short to really enjoy (Probably not your fault). PLEASE permit us to turn it off."

Pros: "It eventually ended"
Cons: "Spent almost an hour before actually taking off. Terrible service. No"

Pros: "How fast they recovered my lost bag"
Cons: "Small plane, had to check in one of my bags at the gate, took forever to retrieve my bag, thus I missed my connection"

Pros: "Easy booking.. Service with a smile.."

Cons: "Customer service via phone was unhelp and kind of snarky. She knew I was several thousand miles from home trying to get back, but wouldn't arrange for me to get on a different plane without a $650 fee. Another airline would have bumped people off their flights so I could get hiome. I was not pleased that my missed flight couoldn't be accommodated reasonably. Apparently my ticket was wroth nothing..."

Pros: "The crew was awesome for both of our flights! Very pleased with United!"

Pros: "Fast boarding"
Cons: "Crew didn’t wear masks correctly."

Pros: "Easy boarding"
Cons: "FREEEEEEEEZING on the plane so some of us asked for them to turn up the temp but they never did. So cold I pulled out all my clothes and wore them."

Pros: "Nothing flight was cancelled."
Cons: "After the flight was cancelled, they could have helped passengers find a way to continue to their destination. My son was flying for the first time alone and had no idea what to do."

Cons: "Water/coffee should be free"

Pros: "Friendly employees"
Cons: "Delay and no one staffing the counter."

Pros: "Kind flight attendants for all!"

Pros: "Everything was very nice."

Pros: "I arrived safely, so that's pretty much all I care about."

Cons: "The drinks and foods cost more expensive and the bag costs more worse. That's very bad. I don't like it. Southwest airlines offer the best everything FREE to save money!"

Pros: "The rest was okay"
Cons: "It was delay"

Pros: "nothing."
Cons: "I was charged $45 for a carry on both ways which was not disclosed via your site. Adding an extra $100 to my ticket for no good reason sure did put me in a foul mood. seats don't recline and other than water, you had to pay for anything to eat or drink on the flight and I mean anything. This is a terrible airline and I'm surprised it remains in business at all."

Cons: "Flight was delayed more than 2 hours."

Pros: "Left and arrived on time"
Cons: "Tray tables are the size of postcards; no TV. Charged even for a soda. Charged to carry on luggage. This airline nickel and dimes you worse than any other."

Pros: "The actual flight was good...Pilot took off and landed well. Informed passengers of upcoming turbulence (which wasn't to bad)."
Cons: "The flight attendant responsible for taking the orders in seats 22 DEF, totally ignored me. She didn't ask if I wanted to buy anything. Maybe because I'm black she assumed I couldn't afford to buy anything?!?! Anyway who cares?!? No one reads these reviews or will do anything about it!!"

Pros: "Bird was clean; crew was pleasant; flight was on time. Can't ask for much more."
Cons: "The layout of Frontier's planes, understandably, is to maximize the number of passengers while minimizing weight. However, the "lawn chair" (for lack of a better term) seating does not give a sleek, modern look; more of a cheap (and uncomfortable) one. This flight was about 2 hrs, and I couldn't sit in those seats much longer. As for the food/drinks comments, as many other travelers have noted, my suggestion is to either go back to the old school program of no-charge can of soda and small bag of pretzels, or don't even have a drink cart.....you're just making people mad in an, already, stressful environment for most."

Cons: "Getting nickeled and dined for literally everything"

Pros: "Very affordable"
Cons: "You get what you pay for"

Pros: "The service was fine but the turbulence really was tough."
Cons: "Everything else."

Cons: "Rude lazy attendants. No effort to offer even water to me on a two hour flight. All they wanted us to do was clean up trash to make their job easier. Nickel and dimed and this kind of service?????? Also didn't need a repeated 15 minute sales pitch for a credit card!"

Pros: "Nothing"
Cons: "Customer service is aweful. Fees a ridiculous. Will never give this company another cent of my money"

Pros: "We got from point a to point b. 1 included personal item was perfect for my quick trip."
Cons: "1 hour delay on a 3 hour lay over. I did not have space or accommodations to be able to work comfortably on my laptop. Tray tables were entirely too small. No ability to recline seats on 10 day old plane. No plugs on plane."

Cons: "Delayed on the way to. Had to wait to get to the gate on the way back. Extra charge for my tiny carry on which should have been a "personal item". From Denver and I've flown frontier for years....never again"

Pros: "The flying."
Cons: "$40 carry on bag fee, late boring, gate was occupied when we got to Denver, everything cost money on the flight. It was a budget flight, and you feel it in every way... also, factor in the bag fee when figuring savings"

Cons: "Waiting for 20 minutes to get off the plane."

Cons: "The flight was changed and I was not notified"

Pros: "Nothing."
Cons: "I will never be using Frontier again! I had the worst experience ever with them yesterday. When I purchased my ticket, I was not aware at any point that I had to be checked in 45 minutes prior to the flight time. With any other airline I have ridden, I have never encountered such a rule. I was trying to make a flight home after driving into town to help a friend move and tried to check in online when I was 45 minutes out from the airport. The frontier app let me pay for my carry on (which, at the time of purchase, I had no idea that I would be charged for a carry on), but then wouldn't check me in. How is that ethical? Charge me for a carry on when checking in isn't even an option?? When I finally arrived at the airport, the Frontier staff was rude and unwilling to do anything to help me. No refunds, no options, nothing. I was told that I would need to pay a $99 re-booking fee and then pay for whatever additional costs would be to buy another flight. Had they helped me get my boarding pass, I would have made it to the gate and onto my flight. What a scam. It is complete bullshit to not be willing to work with your customers at all, especially if you want to retain business. Good luck with that, because you will not have my business or that of any of my friends and family after my experience yesterday."

Cons: "I was never notified of a time change and had to rebook with south west for $280 very angry with the whole experience. Will never fly Frintier again."

Pros: "Planes are newer, seat backs are thinner which gives the impression of more leg room, not very comfortable though unfortunately."
Cons: "For what looks like a competitive airfare consumers get up charged when it's time to get your seat assignment (ie. pay $9 or $15 or $30 MORE for a seat on the plane when it's time to check in - not disclosed when you book through Kayak of course). To be fair, there was 1 seat available for $0, it was in the last row in the middle...1 seat. I also experienced a first...getting charged $30 to bring my backpack on board as a carry-on. Airlines are now charging to put luggage in the overhead compartment. Same carry-on luggage you'd bring with you on any other airline for free, apparently not on Frontier. $30 for a backpack, wow. Apparently Frontier also claims 'we don't participate in TSA Pre-Check', meaning it's great if you have TSA Pre-check, but given Frontier doesn't 'participate' in this program even if the consumer has paid the $100 and cleared to checks to use this program (which is awesome), if you fly Frontier, you can't use it, they won't put the 'TSA Pre-Check' denotation on your boarding pass. Huh? I get companies like this shooting for operational efficiency, scaling lean, profit maximization et al, however this airline feels like a total money suck from top to bottom. 'We have snacks available for purchase'! Of course you do Frontier, of course you do."

Pros: "Nothing."
Cons: "Everything."

Pros: "very warm staff"

Pros: "The crew had great communication and humor in a situation they could not control, such as sitting on the tarmac for 45 minutes."
Cons: "There were not enough staff to assist in the baggage, as the bags were not unloaded and retrieved for an hour after the flight. The seats look aesthetically streamlined, they are very uncomfortable and the tray table is a joke. It isn't big enough to hold any substantial item to complete work."

Pros: "Flight departed and arrived on time."
Cons: "Seats did not recline, we're very uncomfortable, little leg room, no free drinks or snacks.Frontier charges extra for everything now."

Cons: "They overcharged me for my carry on. The woman at the Frontier desk at the Austin airport agreed, she gave me a phone # to call. I called after I arrived at home and the woman on the phone would not give me credit!"

Pros: "Return flight crew was hilarious!! they made the delay in flight seem like nothing! They were awesome!"

Pros: "I think the only good thing was the fact that we made it to the correct airport and didnt die."
Cons: "Frontier WAY overbooked the first flight. Myself and 4 others sat on a bench and waited to see if we could even get on the flight because it was "overbooked". No warning that this might happen mind you. When expressing my shock that the flight was overbooked, the gate attendants explanation was "Well that's frontier for you!" what kind of response is that? When speaking to the others waiting with me to see if they would be flying or waiting 24hrs before the next flight they said they will probably never fly Frontier again. Fast foward to the second flight, boarding went smoothly, the flight was fine and on time, until we landed and there was "another plane at the gate and it would be 5 minutes or so." 20 minutes later we start moving toward the gate only to get a second announcement that there was no crew to dolly us to the gate and we would have to wait til someone got us. Tack on another 40 minutes and we had been waiting in one spot for an hour after landing turning our 2 hour flight into a 3 hour flight. A woman even missed her second flight because of that delay! Seriously crazy that an airline can be so irresponsible with their customers money and time."

Pros: "That needs to be in BOLD print. No wonder why their prices are cheap. Add at least 95$ since you will probably have a carry on both ways. Water is the only thing free. Sodas are expensive too. I am flying South West next time."

Pros: "Initially; I liked the price of the ticket"
Cons: "But. That price was an outright lie. That price was only to get a spot on the plane. Then you had to choose your seat with an up barge of anywhere from $11-$35. Then you have to pay for a bag. Zero free bags. Carey on cost $40. $40!!!! And a checked bag is $35. So my low prices ticket actually cost me another $51 plus tax above advertised. Then the plane. Plastic seats that do not recline or have any head support adjustment. I'm 5'10" and my knees touched the next seat. The over 6' gu next to me had his legs spread into both my area and the woman next to him just to try and fit at all. The only complimentary drink was water. No entertainment screen and the most laughable tray table I've ever seen. I had a cup of small Starbucks coffee and it wouldn't even sit flat on the little narrow tray. I used to fly frontier exclusively because the prices where really great and so was everything else. I'll never fly frontier again if I can help it."

Cons: "I lost my bag on a direct flight from Denver to Austin. Once Frontier lost my bag, a representative gave me a claim number and a number to call for inquiries and a status update. I called the lost baggage claim department several times and not once did they answer my call. I had to leave a few voice mails to an automated system. Finally, someone after 12 hours from leaving my initial voicemail called me back to let me know that my bag was found and would be delivered to the my friend's address. The bag was not delivered to my friend's house until 1:30am the following night, which was 36 hours after my flight had landed in Denver from Austin. Frontier also said that they would refund me the $40, but that they happened either. Frontier has very low air fares, but I now know that is in fact very deceiving and ultimately not in fact true. Asking customers to pay $40 both ways to check a bag is not worth it if they can't even safely transport a bag on a direct flight."

Cons: "Flight delayed both ways $40/each way to carry on your bag Last time I fly Frontier"

Cons: "Lack of Handicap boarding Lack of leg room Seating unconfortable"

Cons: "30 wait to get off the plane"

Cons: "Suprise! you get to pay $60 AT THE GATE FOR YOUR CARRY ON!! What?!!! And then you get to angry walk to your incredibly uncomfortable (non-adjustable) seat to find that there are no tvs, no free snacks, and up charges for soda and juice?! Never again Frontier, never again"

Pros: "Not much"
Cons: "Fees, fees, charges, nothing included."

Pros: "Friendly"

Cons: "Delayed three hours and Frontier nickle and dimes you for everything."

Pros: "Nothinf"
Cons: "I missed my flight on a Thursday and won't be able to leave until Monday morning. Very unhelpful at the original gate in Austin and waited for 2 hours in line to change my flight"

Pros: "Our flight was cancelled and there was no customer service to help us rebook - we are heading to the airport now."
Cons: "Lack of customer service"

Pros: "Friendly and helpful staff"
Cons: "Nothing"

Cons: "The flight attendant was extremely rude and condescending to a handicapped man both on the flight and after he exited the plane."
