Airline reviews
Pros: "Nice clean plane and every other seat being open is very reassuring."
Pros: "Nice clean plane and every other seat being open is very reassuring."
Pros: "The crew did their best to deal with delay."
Cons: "There was an absolutely awful job done by both Delta and Kayak of informing us if additional delays, new gate assignments, when the plane would be reboarded. Also, people were quite angry that the plane had to be cleaned between the time we got off and the time we reboarded. Just get us home."
Pros: "Flight was mostly uneventful, which is great! Right after takeoff we made a complete circle and no information was given as to why, but we assumed it was air traffic."
Cons: "KAYAK did not informed us we have to pay for our luggage!"
Pros: "You're kidding!!!"
Cons: "Seating 3 across. the passenger on the isle seat got served and the other passenger and myself were ignored. NO SERVICE!"
Pros: "There is Nothing that like"
Cons: "If you allowed me to get in this flight everything would've been fine.?"
Pros: "The A/C worked, that's about all"
Cons: "Old plane, no entertainment in head rests, had to use iPad not the same movies to choose from. Seats were so uncomfortable."
Pros: "Even in the absolute freezing (-40F) the plane landed an hour early into Minneapolis. Was only delayed 20 minutes leaving. Crew did amazing to get the plane going."
Pros: "I love flying Delta. We left on time and even landed about 20 minutes early and all our baggage was at baggage claim by the time we got there. There is also a great amount of tv/movie options to choose from on board. The flight went by so quickly."
Pros: "Delta Flights are always enjoyable and the staff is always treats you with courtesy"
Cons: "The only thing I don't understand is how the planes are loaded. and this is only a comment and I know you and others carriers have there way of doing things. I just don't understand why you load the first section of the plane first and the back of the plane last, It looks like you would want to load the back and come forward so everyone is not getting hit and stood over while everyone is loading."
It was Japan Airlines that was excellent. I don’t know why it shows American Airlines.
Pros: "Nothing at all"
Cons: "Everything from boarding to landing the flight and atleast could have informed the next connection that we would be late by a few minutes so we could have caught that flight. Instead we ended running around the airport for no reason."
Cons: "See my earlier comments on the first leg of the flight"
Pros: "Flight crew were good."
Cons: "My checked baggage did not make it on this flight even though it was checked in over an hour before the flight. I have been getting the runaround at the Baggage Claim area and on the phone. It may be delivered tomorrow afternoon and I have food items in the baggage and it may not be delivered until the afternoon of the next day. They don’t have a good baggage tracking system."
Cons: "Try not to loose my luggage next time full of my family’s Christmas gifts. It was a short flight and a giant Leopard print bag. Crew was rude, didn’t wake me to let me sit up. She just shoved my seat forward"
Cons: "5 hour delay caused us to miss connecting flights so got stranded in Los Angeles."
Cons: "If we had access to the WiFi to watch shows earlier like United does, that would be nice."
Pros: "I arrived safely at my destination"
Cons: "Flight was turbulent, plane was messy, crew had a hard time noticing when passengers needed anything."
Pros: "The crew were super nice. All the people in the SAN were very nice."
Cons: "They didn’t have headphones :("
Pros: "Super-friendly crew, really under-booked flight so LOTS of empty seats"
Cons: "“Free” WiFi was really $10, unless you have TMobile"
Pros: "Service was really good. Everything on time."
Cons: "My tv was the only one not working in the entire plane! LAME!"
Pros: "Nothing"
Cons: "A flight not canceled due to mechanical failure. A staff that were actually helpful. United could care less and I will never fly with them again"
Pros: "Jet Plane"
Cons: "No entertainment. No charging point for personal device in today's age. Seats that can't get any smaller, yet, still does. Seats that barely recline and yet have to be brought upright during take-off and landing. Maybe common theme between airlines, but, it stands out. Salty pretzels probably the poorest choice for free handout snacks. No choice of course."
Pros: "crew was friendly. flight was on time. everyone at united, from the people checking me in and taking my bags to the flight attendant were incredibly friendly. I appreciated that--so many workers make a bad situation worse by being rude to their customers. I truly felt that United workers were happy to help."
Cons: "the size of the plane. wow, is it small!"
Pros: "At least I could watch movies."
Cons: "After a long journey in Japan, flying United back to the U.S. was a rude awakening. Their crew has no regard for the manners or respect in Japanese society. I was sitting in an exit row aisle behind a restroom in economy. The staff kept bumping into me and my entertainment system as they tried to rush up and down the aisles. Really taking a breath and walking more slowly could have resolved this. At one point, the staff almost caught my arm between my seat and their rolly cart. The plane was old and in disrepair. My neighbor's entertainment system screen needed to be propped up with duct tape. The seats are stiff and uncomfortable, and the headrests are designed so that if you have a U head support, it will collide with the headrest and curve your back into a C. Some staff could use a refresher on basic Japanese. One flight attendant kept asking everyone "US Citizen or 日本語？" which means Japanese Language. Those are not mutually exclusive questions for many bilingual flyers. I usually tolerate airplane food, but this was the first meal I could not eat on a plane. It was eggs and hash browns, and it was so mushy and salty, I decided to pass. The bathrooms dirty quickly, and are a disappointment compared to the amenities provided on your basic Asian carrier. No toothbrush. No hand lotion. Just soap. We left Narita after 5 pm, and were served this weird dinner breakfast meal. Six hours later (of a 12 hour flight) it was about 11 pm in Tokyo, and 7 am in the destination city of Houston. Might as well get back to American schedules? I don't know, but when I was naturally getting tired and putting on my sleepmask and earplugs to get some rest, a rude flight attendant kept asking me if I wanted breakfast or orange juice, shoving items in front of me (with one hand, a no-no in Japanese culture), and repeatedly asking me despite me shaking my head no. I really don't know where they hired these people. My bag got held up by customs in Houston, and United transfered it to a third party courier service who tried to call me at 1 am to deliver it. That was a bit later than I expected, and I missed the call. The next day, I tried to call the driver, who hung up on me! I called their customer support, who was unable to contact the driver or the delivery service. Just who did they hand my bags to? Thankfully, after an 18 hour wait, I got my bags back, but it was a stressful wait. Throw a dart at a list of Asian airlines, they're all better than United."
Cons: "The flight was late, which I realize isn't any one person's fault, but it was annoying. We were actually taxiing almost as long as we were in the air! The part that was really frustrating was that my infant's car seat was damaged, but United refused to acknowledge that they did it because it hadn't been something severe like being run over by a forklift. The good news is that I now know to avoid flying United."
Pros: "The food choices were good and the service was excellent, Always kind and responsive to my needs and attentive."
Cons: "Boarding could be done by letting people with window seats being seated first, then the middle seats next and finally aisle seats last! That way people would not have to get up from their seats after they have been sitting down to get back up to allow the people in the inner seat to get to their seats a pond boarding the plane after the people in the aisle seat are already sitting!"
Pros: "The leg from Denver to vegas was awesome"
Cons: "The first leg didn't have any snacks and a cold continental breakfast. American and Delta's breakfast is much nicer. But worth the price for that portion of the leg."
Cons: "Having a medical issue, requested for an isle seat but unsuccessful."
Pros: "THE SECURITY CHECK WAS A BIT TO MUCH, BUT OVERALL A WONDERFUL FLIGHT."
Cons: "The check in/bag drop process is terrible. Took 45 min. No explanation. No help."
Pros: "The young man who finally boarded passengers after multiple delays stayed very calm and profession and communicated clearly to expedite our boarding process."
Cons: "Everything. We had three gate changes and an hour delay. Frontier communicated these changes terribly. The seats were painfully uncomfortable. No beverages available on the flight unless you paid. The entire A concourse of DIA seemed full of angry Frontier passengers. The customer service was packed"
Cons: "Frontier has great prices, the bag thing is a pain, but you get what you pay for, l just work around it..."
Pros: "Price was right and my golf clubs arrived without incident."
Cons: "Flight was delayed over 1 hour with little explanation."
Pros: "The crew was nice, boarding was easy"
Cons: "The seats and space are horrible, it is almost impossible to stay seated during the duration of the flight because the seats are so uncomfortable and if you are taller like I am you will have no leg room and no support past your shoulders"
Pros: "The crew was wonderful"
Cons: "In one weekend had two flights that were very delayed. Plus the return Orlando flight the cabin pressure was not regulated very well."
Pros: "One of the flight attendants was extremely nice"
Cons: "Guy taking tickets at the gate was too busy chatting with the desk clerk"
Pros: "Boarding was easy."
Cons: "Uncomfortable seats even for 2 hour flight, & who charges $2.99 for a can of coke?!?"
Pros: "Took off on time and arrived early, which was good."
Cons: "Again, Frontier charges a ton of fees and provides no entertainment on the flight. Plus no complementary food or drink. When we landed we sat on the tarmac for a long time and then the checked luggage took 90 minutes to reach the carousel. This was a disaster and very disappointing."
Pros: "We landed early to and from that was nice.. The crew was very nice.."
Cons: "Had to pay for coffee other than that it was great"
Pros: "The boarding was relatively quick and it was timely"
Cons: "The additional costs at Spirit are ridiculous. The flight price totally fools you on the front end given the additional costs that come later. That said, the comfort is poor. Seats don’t recline and are poorly cushioned. I will not be choosing Spirit again for my future travel needs."
Pros: "Nothing since I didn’t make this flight."
Cons: "Actually making his flight and Not sitting in the airport an extra 5 hours. Then having to rent a car because I had to fly to another state than my original destination."
Pros: "No one sat next to me."
Cons: "I missed my connecting flight that costed me $700 from work."
Cons: "flight was delayed first due to weather and then due to mechanical difficulties. this is never a good situation, and they dealt with it about as well as they could, but why TWO bad things had to happen on the same flight is a bit puzzling."
Pros: "In flight crew actually made people listen to the pilot. Boarding was fast and simple."
Cons: "Plane and seats to firm and to small. A sensor went down so they decided to hand write information from the tower."
Pros: "I don’t like anything at all the worest airlines ever"
Pros: "Delay, mechanical issue, more delay, new plane, take off four hours later. Don’t waste your money on Spirit. They haven’t figured out how to be a big boy yet."
Cons: "Delay, mechanical issue, more delay, new plane, take off four hours later. Don’t waste your money on Spirit. They haven’t figured out how to be a big boy yet."
Pros: "The boarding was smooth and the flight went very well overall"
Pros: "Everything accept there were no free snacks and had to pay extra for luggage"
Cons: "No snacks or entertainment and also they need to allow some type of luggage for free"
Pros: "Flight was cancel and the flight customer service mention that it wasn't non refundable on the behalf of the flight I have a whole lot to say very disappointed this is the first time I ever flew and the action that were taking"
Cons: "Horrible experience not a reliable flight"
