Cons: "My flight was cancelled and instead of getting a cancellation notice, I received a “your flight has been updated” email which indicated that my flight was changed from Wednesday to Friday. Unacceptable!!!"
Pros: "The crew was very good, caring and concerned."
Cons: "I don't think anything, this was another amazing flight with Alasks"
Cons: "Great flight back"
Pros: "Empty plane so lots of space to lounge and quick boarding"
Cons: "Sat on runway for hour after plane landed, just waiting for a gate. How is this even possible? With no offer of beverages or food. Or updates. Crew was hardly seen maybe once or twice on a six hour flight. When asked to take trash, they would reply, we are only doing drinks at the moment."
Cons: "Really bumpy flight. And flight was late."
Pros: "Nothing I can think of at the moment."
Cons: "I didn't like anyt of it."
Pros: "Seats were decently comfy. Good entertainment selection."

Pros: "Every aspect of the trip was above our expectations, comfortable seats, delightful staff, good food and on time service."
Cons: "Paid for and reserved a premium seat 6 weeks before flight but got reassigned to a non-premium seat upon check-in. I had to call customer care for a refund of the premium upgrade. No more live TV unlike the old Virgin America."
Pros: "Bathrooms were relatively clean"
Cons: "Crew was rude and very unhelpful. Made smart little comments to many passengers."
Pros: "Movies were free"
Cons: "We were delayed for over three hours, then food was delayed after we not eating for hours and hours. The seats are the smallest seats I’ve ever sat in on a plane. Can barely fit a small carry on sized bag under the seat in front of me. Ran out of food less than half way through the flight. Offered zero compensation."
Pros: "Crew was very attentive and friendly yet they give you your space. I know there is no personal space in an aircraft however it felt like it. Great job."
Cons: "They cancelled my 5:30 pm flight and text me that they put me on a 6a.m. flight the next morning without offering me a hotel or anything. I had to make new arrangements myself and the only option was to fly out earlier in the day and lose a day of sightseeing and time with family that I made the trip for in the first place. I had to race to the airport to get there in time. It ruined our trip."
Pros: "The plane was on-time. Boarding was easy. Flight attendants were very helpful. They helped passengers get to their seats, find places for their luggage. Entertainment options were good. Bags arrived within a reasonable amount of time"
Cons: "I wish they would provide more food options or at least stock a few more of the ones they have. The fruit and cheese tray sells out early making it a long flight without real food. I don’t consider chips and cookies lunch food."
Cons: "That there wasn’t anyone to meet us at the gate and we had to wait on the plane."
Cons: "Auxiliary generator broken so plan got hot very quickly. Flight was 2.5 hrs delayed due to another mechanical failure. And then once we were in air they generously notified us that the WiFi was broken. Utter garbage."
Pros: "Virgin plane, flight crew great"
Cons: "No headphones, no snacks. Tray tables not clean."
Pros: "Great plane. Nice to still have free entertainment to watch!"
Cons: "No complaints"
Cons: "There were no vegetarian/vegan options for meals. In 2018 it’s unnacceptable to have ZERO veggie options, especially on a flight to LA. Come on! I ended up having to pay for 2 meals that I could only eat parts of. And it took more than 1 HOUR for them to bring me these meals. I’ve never had to wait more than 5 mins for a meal, that I PAID for, to be delivered to my seat. I was starving, forced to waste money on meals I couldn’t fully eat AND had to wait over an HOUR to receive them. I am beyond disappointed."
Pros: "Seats, movie selection, drinks"
Cons: "No headphones available both ways and my AirPods don’t work with system. Flight attendants this leg were not so friendly."
Pros: "I didn’t know what to expect but I had an excellent trip. Enough leg room for a five hour flight. The entertainment was excellent, many choices of movies. No food was provided, you have to pay for any food or snack. You are given a cup of soda not the whole can. But I came prepared with food and drink. Overall, very good airline!"
Cons: "No food or snack are provided unless you purchase it!"
Pros: "Even the baggage was excellent. My bag was on the belt before I got there"
Pros: "Very Friendly staff"
Cons: "unable to manage the reservation and select seats to put the 2 of us togehter"
Cons: "The new TV program choices. I miss the Direct TV live program choices. It made the flights go so much faster! The few episode choices was a huge disappointment. This was one of the things that made Virgin America flights special!"
Pros: "I have been flying for many years, and must admit that the flight cabin crew was incredible. Professional, attentive and on their feet for 95 % of the time. Thank you"
Pros: "The crew is kind and I appreciated their service while flying"
Cons: "For my first time flying with them, you would hope that your luggage makes it to your final destination. Since it didn’t, many plans in Hancock had to be rearranged and my ride has to rearrange her schedule. Not to mention, I had to rearrange my schedule again just to pick it up at the airport the next day."
Pros: "Getting to where I needed to go"
Cons: "Stopping the plane to fuel at another airport understandable. But then you ran out of food for purchase on the first flight (I was sitting in the back). Then connecting at LAX was horrible. Everyone had connecting flights. Off the plane onto a bus. then through customs then shuffled outside with no guidance from employees. Finally I found someone to ask bc 15-20 people were around me in the same boat. Where the f do we go we wondered. The employee was insanely rude. I’m attentive and I listen. he was saying pay attention I told you go right blah blah blah. He was literally standing there with his arm out pointing right and never said a word to anyone. So once we figured out to go outside and right we had a stressful ten minute wal hoping we were going the right way. We were! We get to tsa and have to go through screening again. Which is insane bc we just got off a plane. The tsa agent told us this happens everyday with a smerk. On top of her attitude, her and the two other lazy ladies on her line were painfully slow. The other two lines went at least twice as fast(no exaggeration!) made it to gate 66 to find it was changed without notice to 63. Made the flight by two minutes or less sweating from running around!"
Cons: "Passenger next to me seated in the aisle seat had a seat belt extension and needed two seats. I was in the middle and had a very uncomfortable flight. His arms were on my side and fortunately my husband was in the window seat and I leaned into him the entire time. The mans wife was not next to him but across the aisle and I understand why! He also had very poor hygiene."
Pros: "Nothing"
Cons: "Everthing they got delayed in L.A so that mess up or connecting flight to cebu come on now if we are able to wait for your crew why cant u wait for your paying customers for 10 mins more?"
Pros: "Great crew and good service"
Cons: "Flight was late. Seats were small and cramped. At LAX, had to wait on board 20 minutes for bus to immigration. Then had to stand on bus for 15 minutes while drivers chatted outside. Immigration was a nightmare at LAX. Never again."
Cons: "I haven't flown a first class this poor ever. No blankets, we were not offered drinks until we were at cruising altitude, no magazines, felt very dirty and unkept. Food was less than desirable. Alaska needs to improve their overall service and cabins."
Pros: "Great prices, comfortable seats, enough space, and no extra fees for the additional bag I checked in. the staff members were also very polite, welcoming, knowledgeable, and helpful."
Pros: "Flight was delayed for 2 hours with no compensation"
Pros: "Terrible service, rude, impatient crews. No food provided for a 5 hours flight, only basic drinks."
Cons: "Make sure transit with more comparable service throughout the journey."
Cons: "I wasn’t one of the passengers but it’s unbelievable that United was denying passengers in zone 5 to take their carry on. You can’t take what you are going to use during the flight, it is not normal. Is that a joke or what?"
Pros: "Nothing"
Cons: "Blankets"
Pros: "Nothing"
Cons: "Everything. I paid for seats 7 months ago and they didn’t honor them. We sat seperate in the middle when we paid for aisle and together. No food, poor service, overbooked and almost didn’t allow us tickets at all. We were a connection from another airline. They damaged brand new luggage."
Cons: "The food was the worst. The setup was old. The staff was indifferent"
Pros: "Crew was really friendly."
Cons: "Seats are not very comfortable. The standard has decreased: leg room is reduced, and options to gain 1 or 2” of legroom, is so pricey that it feels like ‘highway robbery ‘."
Pros: "Crew was amazing, doing a good job keeping everything moving"
Cons: "Food was not good, bland"
Pros: "The food was quite good actually"
Cons: "comfort level was terrible"
Cons: "No WiFi functioning so nothing to do for five hours when you counted on having WiFi. Now I will always bring a book"
Cons: "The WiFi system is very slow"
Pros: "Crew were solid, competent"
Cons: "You could buy food, but no included meal for a six hour flight. The food for purchase was just snacks. Additional seats are very forward, uncomfortable even in Premium seats with reclining."
Pros: "After sitting on the aircraft for 6 hours the day before, it left on time The Gate attendant ( older cellar gray hair/glasses tried closing the gate as I arrived!( Quoted... didn’t think you’d make it... grabbed my boarding pass & switched me from my window (which I reserved back in JUNE) & put me in center seat( I’m OT A GOOD MIDDLE) this woman should be fired... seriously!! She was an older woman with baaaad attitude then when we sat there for 4 hours got all FAA on us RE FAA RULES).. then the Captain & crew had to deplane & we waited anithev3 hours for new crew...bad weather or not.. this was very very very badly managed Further more... TSA REQUIRED me to open my suitcase & place my duty free merchandise in it, even tho it was a sealed sew thru bag... AAAND threw away my 1/2 empty ( under 3 0z) copperyone & shave cream !?! ETH?"
Cons: "Apathetic crew... 58% sugar cranberry/ apple soft drinks!?! Maple cookies?!? The tightest seats EVER?!? The worst domestic flight in decades"
Pros: "Domestic flight from IAD to LAX was not great as usual — small space, overbooked, no food, entertainment slow. But LAX-INCHEON-MNL was GREAT! Extra space, efficient, helpful and happy crew ready to help passengers! I was surprised by this!"
Pros: "Seats very uncomfortable. Food poor. Downloading an app for entertainment... a joke!"
Cons: "Seats very uncomfortable. Food poor. Downloading an app for entertainment... a joke!. 737 far past their prime."
Cons: "Really United? They STILL charge for inflight entertainment. Not like I could’ve used it if I wanted to because my screen turned off and on the entire flight. Not so great on a red eye. One of the crew was helpful, the rest short with all passengers."
Pros: "Had xtra legroom and Wi-Fi"
Cons: "I paid the xtra $99 for the economy plus but my headphone jack didn’t work so I couldn’t watch a movie and my tray table was broken so I had to hold my drink and fumble with my food. The flight attendant tried to fix it but couldn’t. Made my 6 hour flight feel like 12 hours."
Pros: "Boarding was smooth enough"
Cons: "I'm a disabled person, I need an aisle seat for my long legs and busted knees, but the aisle seats had about 1/3 the space for feet as the other seats. My knees were pushing into the seat in front of me. Drinks went around once about 1 hour in to the 5 hour flight, but not again after that, though they came by to collect trash 5 times. Flight crew were polite, but some clearly didn't want to be there. This is the first flight I've ever been on where I was in tears from pain, and i felt like i couldnt ask for water or even the wheelchair I needed after the flight."
Cons: "Very crowded. Seat in the back near toilet has much traffic and sitting on the aisle- much jostling. No entertainment unless you brought your own device."
Cons: "Being jostled by carts and people walking by"

Pros: "United Airlines abuse of the man on Sunday is shameful and I will never fly United again!"
Cons: "I don't like how they beat and dragged that poor doctor from that flight. #fireoscarmunoz #boycottunitedairlines"
Cons: "Lost our bags which we still haven't received. Seats didn't recline. Airplane wasn't stocked with enough food for the passengers. This was on top of both flights being very delayed first due to weather and then maintenance."
Pros: "The movies, the seats wre confortables."
Cons: "Too long to boarding, very desorganized, my seats were wringful assugned took it to long to reassign the correct seats numbers, the flight was one hour delayed, the food too expensive."
Cons: "Missed my connecting fight due to my aircraft having malfunctions, as well as my flight home being delayed three times. Worst flying experience to date."
Cons: "It is outrageous that those seats and that legroom is legal. Something has to change!"
Pros: "Nothing I cuold think off"
Cons: "Too many delays, change of gates, maintenance check is too overwhelming. My Houston flight is unbelievable. We stayed were delayed for almost 5 hours . Wifi is not working"
Pros: "Nothing"
Cons: "The terminal number on my ticket was wrong and when me and some other customers asked the flight lady what was going on she was of very little help. Not only that but she was making a personal phone call. So I had to rush to the other end and then just to find out that they didn't have enough room to put my carry on so I had to place it enbetween my legs which made for an even more uncomfortable flight. Also one of the flight attendant was particularly rude and kept saying she had to do her job in a very rude tone to the point were an older retired man told her he's worked too hard in his life time to be talked to like that. Overall the poorest plane experience I've ever had and I fly quite a bit."

Pros: "Boarding was a quick process"
Cons: "Lack of leg room, two hour delay, no compensation"
Pros: "Nothing"
Pros: "Crew did the best they could, stayed friendly and helpful. Free DirecTV nice gesture."
Cons: "2 +hr delay boarding because of "oxygen tank service on 4 units", additional delay on Tarmac to "rebalance cargo load- luggage loaded incorrectly". Took off 5 hours late. Captain said galley was not fully loaded - row 32, no food for purchase left except 2 bags gummies bears, 1 kid box and 1 bag popcorn. And thanks for shrinking the seat space again...glad I'm only 5'6". Still ridiculous."
Pros: "flight was on time"
Cons: "Rude flight attendants uncomfortable seats zero inflight entertainment unless you wanted to pay $7.99 Having an international ticket (coming from a previous international flight) meant they put you in the LAST boarding group No overhead bin space Overbooked flight"
Pros: "Kind and caring flight attendants and pilot"
Pros: "The crew was friendly. Boarding process was the smoothest I've ever seen."
Cons: "We were delayed but I felt as if the pilot didn't inform the passengers in a timely manner. The passengers were starting to become antsy as we weren't sure why we hadn't taken off."
Cons: "Was asked to pay $25 extra for my luggage. That should have been disclosed up front on the ticket. Not happy"
Pros: "After getting on the flight to sit down and have three children sitting behind me, kicking my seat instantly, the sweet female flight attendant was quick to make accommodations to change my seat. I was moved closer to the front (bonus) and also put in an emergency exit row (extra leg room? Double bonus) I was very happy with the service given by the attendants"
Cons: "Nothing other than the snack mix for free snacks. Peanuts were surely missed!"
Pros: "Crew was friendly"
Cons: "Too cold and no blankets when I asked."
Pros: "I did not like it at all."
