Airline reviews

Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."

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

Pros: "Crew from Washington to Cancún were extremely rude"
Cons: "Smile"

Cons: "Nothing all excellent"

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

Pros: "Christina brown was amazing at gate"

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."

Pros: "Crew was friendly."
Cons: "Wish the seat was more comfortable. Landing was jittery and bumpy."

Pros: "The flight attendant from IAD to MSP called Bernadette was wonderful!"

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

Cons: "Delayed"

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

Pros: "Super comfortable seats. Lots of movie options."
Cons: "Food was not very good"

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

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: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Pros: "Fly attenden alwas with a beautiful smile"

Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."

Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Cons: "Tv"

Pros: "In a pinch they were able t"

Pros: "That I landed safely"
Cons: "1st class was horrible."

Pros: "Everything was perfect !! Staff friendly"

Pros: "Great in every way"

Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"

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!"

Cons: "Check in lines were crazy long"

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: "App is good and convenient to use."

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

Cons: "Delayed two hours"

Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"

Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Cons: "There delay"

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Everything was great"
Cons: "Nothing everything was fine"

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Pros: "nice snack"

Pros: "Crew was great."
Cons: "turbulence"

Cons: "Spacing people out until this covid is over"

Pros: "Everything was great"
Cons: "Nothing"

Pros: "Appreciated the pilot keeping us informed re: turbulence and avoiding it"

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."

Cons: "Speaker volume was too high."

Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Cons: "N/A"

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."

Pros: "Nice staff"

Cons: "Small, cramped seating"

Pros: "Pleasent"

Pros: "Pretty standard flight"

Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."

Cons: "3+ hour flight with no TV/ entertainment"

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: "They got us there quickly."

Pros: "Ahead of schedule"

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."
Cons: "Airline misplaced my boyfriend's checked back with our duty free Portuguese wine in it. It still hasn't been delivered to him the next day. They had three hours to get the bag on the flight."

Pros: "Nothing in particular"
Cons: "Outlet did not work"

Pros: "The flight crew was very friendly"
Cons: "I wish the flight was longer. :)"

Pros: "Same"

Cons: "No tvs!!"

Cons: "the new seats are awful"

Cons: "Plane had no Per-seat entertainment system."

Pros: "Crew"
Cons: "Small plane"

Pros: "Biscoff!"
Cons: "lack of ent. options"

Pros: "Good serice,"
Cons: "Good service to switch flight pattern from greenville to new bern but still a delay that cause a 2 flight connection. Lots of on-line issues with check-in, overall a stressful day, hopefully it will all work out!"

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "Everything"

Pros: "Boarding the plane from the back first saved longer queues. Unfortunately people cheat and the boarding officers don't send them back to the right queue. Toilets were clean. Staff excellent. I was glad all my flights were stuffed to the gunnels. Presumably that is best for the environment rather than lots of planes with fewer passengers in each."
Cons: "Passport control with new computer ID checks was fast. Baggage was slow coming. I booked through Netflights and they didn't book me a good seat. If I could have changed it myself they should have told me. On the way to Tampa on 3rd March I couldn't check in within 24 hours and had to wait half an hour while they changed our plane. BA used to do short science programmes which I loved. Shame these have finished."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

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: "I did like sitting on the left side of the plane. There's a little more room. I feel it's horrible how the airline charges so much and cram so many seats in one air craft. Making it a miserable flight."
Cons: "See above"

Cons: "no food"

Pros: "The flight was on time. It was serviced well by very friendly flight attendants. I enjoyed it very much."

Pros: "Very friendly staff"

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

Pros: "I liked sitting next to my friends."
Cons: "Lack of leg room"

Cons: "The service was terrible, 4 hour traveling and not food."

Pros: "This flight was cancelled"
Cons: "Hire better competent people"

Cons: "Wider seats and more leg room"

Cons: "United express flight Tucson to Denver and Denver to Tucson...feet were freezing on both flights."

Pros: "Not much, don't really like flying at night. The crew was nice enough."
Cons: "Our flight to Denver was delayed by 3 hours, so I had to wait for 5 hours. Supposedly we were waiting for another plane because the original plane had a damaged wing. Who knows if these things are true. Maybe they just don't have enough pilots. I missed my connecting flight. Less time unboarding"

Pros: "Crew and entertainment."
Cons: "Offer more food and beverages due to long delay and sitting in the plane for over an hour before take off."

Pros: "We made it home safely and on time."
Cons: "We were sat in the very last seats near bathroom which was noisy and uncomfortable. I actually paid an extra charge so we could be sat together. In flight entertainment didn’t work in my seat. One piece of our luggage was lost."

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: "Flight was delayed by 3 hours. Seat bottoms are very short on this plane--several inches shorter than normal."

Cons: "Crowded planes."

Pros: "Crew was pleasant and did their job well"
Cons: "The de-ice took way to log and not enough leg room"

Pros: "Good experience. Brought my own entertainment. Comfortable seats for economy cabin. Friendly flight attendants"

Cons: "Second standby adventure of the day got longer as inbound flight was late."

Pros: "Nice new interior"

Cons: "3hour weather delay!"

Cons: "My wife and I traveled with bicycles packed in standard boxes and got hit with a whopping $230 charge per bicycle out of the blue. We were expecting no charge because the bicycles were our only check-in baggage for the trip. Couldn't believe the lack of transparency with which we got hit with this charge. Qantas, Air New Zealand, and other airlines we've taken bikes with us on our flights have charged nothing when we traveled in the same fashion. So, if you are a bicyclist traveling with your bicycle, I'd avoid the United-Lufthansa duo."

Cons: "Gate agent ‘bag Nazi’"

Pros: "On time courteous staff excellent service"

Pros: "Leg room 7 aisle"
Cons: "Pretzels on a 4 our flight? There should have been some food"

Cons: "Never made it on that flight"

Pros: "I made it safely to my destination"
Cons: "I have been flying Lufthansa for over 15 years and the service is steadily declining. It started with issues during online check-in, a delay in Frankfurt which resulted in a very tight connection. I had to leave my bags behind to make it and the ground personell was of zero help. Oh, and premier silver status is good for nothing on Lufthansa. Thanks StarAlliance."

Pros: "Arrived almost an hour early which was great."

Cons: "Flight was delayed for a hour and half because of equipment. Credit goes to United for promptly putting use on another flight that just came in from Denver. All in a it was a long day."

Cons: "Boarding at Dulles was stupid. The line for 1st class and Premier was against the wall, so these passengers had to fight their way through the lines for passengers in sections 3,4,5 just to get to their line. It would make more sense to have groups 1 & 2 in lines which face the door, and keep the lines for 3,4,5 as they are--that is, parallel to the wall. Or, have the lines in the opposite order, so that 1&2 are closest to the concourse, and 5 is next to the wall I actually felt sorry for these 'privileged' passengers who had to fight their way through the other boarding lines just to board when their section was called"

Pros: "Your seating was spacious!"
Cons: "The unfriendliness of the crew."

Pros: "Everything"
Cons: "Nothing"

Pros: "I wish it was always this easy."
Cons: "I wish the seats and leg room could be a little more generous for those of us who don't fly first class."

Pros: "Not much. We did arrive alive, which is the best part of it."
Cons: "Late, very late without any explanation. Only one food service in flight."

Pros: "The boarding procedure, and flight were completely uneventful. Flight attendants were nice. Slept through the snack if there was one offered."
Cons: "Seatback entertainment by directv is getting a little old at this point. I didn't test it but I believe you can watch content on demand on your own device instead but it's hard to keep the seat back screen turned off. Be weary of tight international to domestic connections at IAD. I had an hour and a half between flights and made it to the gate when they had called group 5 for boarding. This is with Global Entry, TSA Pre-check and priority tags on my bags. I'm sure many others without the above were not so lucky."

Pros: "Well, the plane didn't crash, so that was nice. The plane was clean and the newer 737-900s are pretty decent."
Cons: "Every time I fly United, I pretty much feel like it is an honor on the level of being knighted to get the privilege to fly with this airline. Thank you so much for being willing to take my money in exchange for a service, United. Bless you. I'm sure if you spend $10k + a year with them, they'll happily massage your feet as you ride along, but anyone else seems to be each flight attendant's personal enemy that they must frustrate as often as possible. Also, thank you, United, you beautiful prom queen you, for changing my seat from a window to a middle because it pleased you. It honors me to be your jest."

Pros: "Pilot made up for a late departure & we arrived in Denver a few minutes early. Skies were abut rough for a short time."

Pros: "The flight crew was welcoming and friendly throughout the flight. Even the pilot walked through the plane and chatted with the passengers prior to the flight and also made an announcement wishing a young boy a happy birthday from the flight crew."

Pros: "Security was quick and efficient. Boarding was extremely organized. The airline attendants were attentive. The pilot on United informed us when the possibility of hitting turbulence occurred so we could adjust accordingly. Overall, great travel experience."

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

Pros: "I liked that they were polite and friendly during the national United flight groundings due to the computer error."
Cons: "I did not like the terrifying situation in which the pilot said we would be landing in 15 minutes (at this point we were close enough to the ground that I could see cars ) but then without any further announcement proceeded to point the plane upwards and started flying up up up so that all the city lights disappeared and all I could see were stars next to us. I asked 2 different flight attendants wtf was going on and they both said "oh he's just looking for smooth air" which was clearly BS because I was in the very last row of the plane and if there had been rough air I would have been the first to feel it. After inexplicably shooting upwards for what felt like an eternity we finally turned around and ultimately landed and guess what, no rough air to be found. Now I know why airplane pilots update you all the time, because when he pulls a maneuver like that without any warning it is terrifying and all I could think of was the suicidal dude in Germany from Lufthansa. Not cool. Other than that the flight was fine and they were really nice despite the like 3 hour delay or whatever it was. It cost me an extra $60 cause I arrived so late my husband and baby couldn't pick me up anymore but they offered a credit for a future flight so it's ok. I appreciate the gesture."

Cons: "Boarding was late, then, after boarding, we were advised leaving was delayed due to no fuel service available, then other problems arouse, over all, we sat at the gate for over 2 hours before take off."

Pros: "Crew friendly, but every thing else simply as usual."
Cons: "No meal if you can' afford first class."

Pros: "Great and attentive."
Cons: "Seats were a bit uncomfortable although very clean."

Pros: "We ran from customs to our gate with 7 minutes to spare."
Cons: "My seat belt appeared to be on the verge of fraying. Too bad we would have to pay for entertainment. It was free on the international flight. The seats were old, narrow and did not have much padding."

Pros: "Easy to board and check in, good price"
Cons: "It was extra to check luggage"

Pros: "Everything was fine"
Cons: "Na"

Pros: "Boarding, crew"
Cons: "Stale bag of snacks, expensive options for entertainment were a little co fusing as far as directions go."

Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"

Pros: "It's seems like no one cares about passengers in this airline.... Rude services"

Cons: "Sorry, I can never give comfort a rating above poor as long as airlines keep making economy class seats smaller and smaller."

Cons: "The leg room was terrible."

Cons: "Male flight attendant gave male psgr next to me 4 bottles of scotch free for having to sit in last row, yet the other 5 of us in last row were not offered anything like that. When psgr next to me became drunk he apologized and needed our help finding his connection when he got off plane."

Pros: "The stewardesses were kind."
Cons: "United didn't even try to hold my connection even though I could have made it if they held it 10 minutes (and it had no further connections). Instead they sent it out early. They had no other flights to my destination until 3pm the next day. The hotels were full and no rental cars were available."

Pros: "The pilot did a great job manning and landing"
Cons: "I can't imagine how little service you get for a long flight"

Cons: "No TV"

Cons: "Stewardess who had to repeatedly ask a customer to put their mask on said “I hope you get it”. Referring, of course, to COVID-19. Horrible."

Pros: "The emergency row seat was good."
Cons: "The hidden carry on luggage fee is terrible."

Cons: "Good service"

Cons: "A soft drink that doesn’t cost money!!"

Cons: "An explanation of why we arrived an hour late. It wasn’t even mentioned."

Cons: "Nevee fiying fromtier again"

Cons: "Website difficult to use for baggage fee payment. Thanks"

Pros: "see headline!!"
Cons: "see headline!!"

Cons: "I had to pay for a Diet Coke"

Pros: "I got to my destination safely."
Cons: "It was incredibly uncomfortable."

Pros: "Frontier employees are great!"
Cons: "No food, no entertainment, no blanket."

Cons: "No reclining seat, no good, chargefor carry on"

Cons: "Fees for baggage and food"

Pros: "Nothing"
Cons: "You can't recline your seat!"

Cons: "We were delayed"

Pros: "Convenient checkin and boarding"
Cons: "Uncomfortable seating"

Cons: "When we checked in at the counter they did not inform us about carry-on charges. Most airlines don't charge fees for carry-ons, but frontier does. We had to pay $60 each for small carry-on at the gate. This practice is unfair to people who are not familiar with cheap airline business models. They should be more transparent about their fees on the ticket and at the counter. This cheap airline is so cheap that they couldn't hire enough staffs at the DCA gate. There's only one staff checking in the tickets at the gate and we had to wait until everyone went into the plane to pay for our $60 check in fees."

Cons: "3 hour late departure, no explanation"

Cons: "You have to pay for every single thing-not a cost savings"

Cons: "No snacks, water etc. too long waiting to depart."

Cons: "Frontier doesn't lease enough gates. Waited 35 minutes after landing for gate to clear. Both flights. Frontier late in unloading bags. Waited 40 minutes at luggage carousel. Frontier lost my bag"

Cons: "No complementary drinks or snacks and it was delayed"

Cons: "We sat waiting for a gate upon arrival for 100 minutes."

Cons: "Frontier charges for the most basic amenities that other airlines provide (non alcoholic beverages and carry-on luggage space)."

Cons: "The three hour delay which was only partially explained by weather."

Pros: "Patient attendants with delay and a sick young passenger"
Cons: "Took forever to be served beverages. Just needed water. Probably due to turbulence though."

Pros: "Nothing"
Cons: "Everything"

Pros: "nothing really stood out."
Cons: "check in wouldn't take cash. plane was delayed 45 minutes on the tarmac. very noisey while sitting and waiting (bad hydraulics?). Plane was old, smelly and very uncomfortable."

Pros: "seating was hard..need more cushioning"

Cons: "Awful seats. The need to pay for every little thing."

Pros: "Well the cost was great until the add ons!"
Cons: "In economy, carry-on $45, 1st checked $40. Advance purchase discount available. Also lets not forget the added charge to pick your seat?"

Pros: "Chairs don't recline. Bags sent to wrong claim area. No leg room. Plane was freezing."

Cons: "I provided my frequent flyer number. You did not provide me TSA Pre-Check ticket. (My frequent traveler number is a TSA Pre-check number)"

Pros: "35 minutes early?"

Cons: "I specifically searched for IAD (Dulles) and you returned results for DCA (Reagan) I think you need to have some type of confirmation window so that people realize that you have switched airports on them."

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

Pros: "Boarding and deplaning were organized."
Cons: "Ticket counter staff were rude to passengers."

Cons: "To have flaps to hold the head on the seat"

Pros: "Crew"
Cons: "Uncomfortable seats, expensive bag fees, will avoid Spirt in the future."

Pros: "Flight was on time and process was very easy"
Cons: "Seats were very cramped and uncomfortable"

Pros: "The crew were personable, communicative, and even entertaining! On top of that, the flight was really smooth - with an excellent landing. The pilot was also very communicative about impending turbulence, which was helpful and comforting. I felt at ease on this flight and think the crew really deserve kudos."
Cons: "At the price-point, it is understandable that this is not included, but water included would be nice."

Pros: "The price upon initial booking"
Cons: "Our flight was cancelled due to mechanical issues after 2 hours on the plane, 3 hours on the terminal. The staff was unapologetic and laughed when informing us of the cancellation. Customer service was abysmal and provided only a refund or hotel room for our overnight 900 minute delay. I will never fly Spirit again."
