Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Pros: "I appreciate that Delta chooses customer safety over profit by not packing flights and continuing to social distance."

Pros: "Efficient and sanitary"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Baggage handling at Wilmington is extremely slow and typically is."

Pros: "Christina brown was amazing at gate"

Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Pros: "Love the fact that the head rests move to support your head better."

Pros: "Crew was nice"

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

Cons: "No meal option and my video screen volume did not work"

Pros: "Loved the plane, people and timeliness"

Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Pros: "Snacks and drinks and movies on point."
Cons: "No cheese its."

Cons: "Boarding was disorganized. Snack mix tasted plain."

Pros: "Getting offered a stipend to change flights - getting my preferred rental car"
Cons: "A direct flight"

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"

Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"

Pros: "The service was good, employees friendly and helpful. The plane was surprisingly nice for such a short flight."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Pros: "love that Delta is now giving out Kind bars. Thanks!"

Cons: "Plane was late numerous times. Boarding was painful"

Pros: "love that each seat now has a USB connection to charge your phone"
Cons: "headphone jack to watch movies shorted in and out constantly"

Pros: "Nice flight nice crew just about as good as you would want"

Pros: "Although boarding began late, it was efficient and we left on time."
Cons: "Even a 29 dollar Comfort Plus seat had very little legroom."

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "Great free movie selection"
Cons: "Flight delayed"

Pros: "Despite a delay, we arrived in White Plains on or close to schedule."
Cons: "The gate agent just kept going on and on about trying to make up the time from a delay (18 minutes ...hardly world ending). The lead flight attendant wasn’t much better"

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "really helpful and friendly service and nice seats."

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."
Cons: "Bathroom ran out of toilet paper, but staff helped fix this after I talked with them."

Pros: "It was crouded seat were uncomfortable otherwise ok"

Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"

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: "Nice staff"

Pros: "Pleasent"

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Pros: "Infrastructure"

Pros: "Entertainment."
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

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

Pros: "Very friendly staff"

Pros: "The plane was new on the interior and comfortable."

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."

Pros: "Yes"

Pros: "Fast and friendly"

Pros: "Good job"

Pros: "How easy everything was"
Cons: "The delay"

Pros: "Very helpful assistance staff, food and drinks delicious, excellent service onboard"

Cons: "More snack options."

Cons: "Only bathroom on the plane was closed due to issues. Plane was cold and cramped."

Pros: "Love United’s service. Nothing to complain about."

Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."

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"

Cons: "Crowded planes."

Pros: "Everything was very nice."

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: "Everything was on time and all the staff were professional and friendly"

Pros: "The variety of movies"
Cons: "No daily wifi"

Pros: "One if the bathrooms was closed and a second one had no running water."

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: "Repairs caused a long delay, they kept us informed but it was a hurry up and wait forever"

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."

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

Pros: "It was dope."

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

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

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: "Everbody seemed nice. Smooth ride."
Cons: "The back bins get filled too quickly. Same issue going and coming."

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

Pros: "Had a stroller, two bags, and a car seat and the check in staff helped us tag everything and loaded it for us. It was nice to see the Billings staff go above and beyond in my families time of need."

Pros: "The connection Austin to Newark, Newark to Amsterdam"
Cons: "plane could be cleaner"

Cons: "Unreliable wifi."

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."

Cons: "Return trip had small planes"

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."

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: "I like having options to purchase snacks during the flight."
Cons: "Boarding process was horrible. Very little overhead bin space available so many carry on's had to be checked. Leg room was worse than other airlines. Had 3 flights cancelled in a matter of 24 hours when other airlines were running flights at the same time. Needless to say - not a good first experience with United and won't be flying them again any time soon."

Pros: "Everything went smoothly"

Pros: "The flight was quick and the flight attendant and crew was very kind and helpful."

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

Pros: "Thanks for the upgrade"
Cons: "Thanks for the upgrade"

Cons: "no complaints"

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

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: "Crew was fine. Mediocre at best."
Cons: "They made no attempt to clean the plane in between flights. There were crumbs, food, and wrappers everywhere. I couldn't believe they charge $40 for a carry on, and for checking a bag... and that's the discounted price you get when you book ahead! This isn't a budget service at all-- they gauge you at every chance, and my flight ended up being more expensive than had I gone with a non-budget airline. At the very least, the customer service should be exceptional, but even that wasn't anything to write home about. I'll remember next time I book not to be fooled by Frontier's prices..."

Cons: "And I can't cancel it because I checked in online the day before? Like, sorry for checking in before a 5 HOUR DELAY. My bad for not predicting that..."

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

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."

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!!"

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."

Pros: "Comfortable. On time departure"
Cons: "Waited for more than a half an hour on the tarmac after landing for a ground crew. Checked baggage fees were high. Very slow to receive checked bag at the carousel inside. Will probably not fly frontier again"

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."

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."

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

Cons: "Seats are so uncomfortable. Then with all the extra fees this discounted fare cost more than if I would've went with my usual pic of airlines. Sat on the tarmac for for over 30 minutes after leaving late from Austin. We had originally expected at least an hour and a half layover and planned on getting some dinner in Denver. With The delay in leaving and sitting on the tarmac we only had about 20 minutes most to find something quick to eat"

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."

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: "We were given no direction as to the likelihood of cancellation; rather, our delay kept getting longer, and no one could explain why. Also, the delay notification email was only sent an hour prior to the expected airport arrival time."

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: "Never friendly, always backed up, even if just 3 ppl in line. Seems person(always seems to only be 1) does not like her job! Just the Austin tx hub. Denver always smiling and flight attendants always happy. Love the price definitely!"

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

Pros: "Friendly"

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

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"

Pros: "NOTHING! They cancelled it!"
Cons: "They cancelled my flight the night before, their website gave confusing information (some places said it was on time, some said cancelled), and I was on hold for SEVEN HOURS!!!!! They never actually answered the phone. Guess what? I went to the airport in person, and nobody was at the Frontier counter for 3 hours. When someone finally showed up, THEY TOLD ME TO CALL THE NUMBER I WAS ALREADY ON HOLD WITH! I told him I'd been awake the entire night trying to solve this issue. SCREW IT! In the end, I went with Delta, costing me $441 more dollars on top of what Frontier stole! Delta was fantastic, the guy who booked me was hilarious and helpful, and I'm never messing with this 3rd party nonsense again unless I get a full refund."

Pros: "The price but then you get charged for everything else without being Told before hand"
Cons: "Seats, loadness. Service, temperature of plane, space, smell, baggage charge."

Pros: "nothing!"

Cons: "All frontier cares about is nickle and diming their customers. The flight was not too much less than any of the other airlines, but I should've done reviews before choosing them. They charge you $20 for your seat on top of your fare when you try to check in 24 hours early. They charge more for a carry on than a checked bag. They do not provide anything complimentary during the flight. Drinks are $2. Overall, I spent just as much as I would've with Southwest of American, but I felt ripped off and unappreciated. If you want a loyal customer base, Fronteir, I suggest you change your flight policies. This is 2016 and customer service is everything."

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"
