Airline reviews
Pros: "Timing of the flight was always good. Efficient flying. Crew was super helpful too even when passengers were a bit too much."
Pros: "Timing of the flight was always good. Efficient flying. Crew was super helpful too even when passengers were a bit too much."
Pros: "The crew did very well. The seats could have been a little more comfortable, the lumbar could have been a bit more stiff for lower back support, the arm rest up and down function did not work, and a little more space between rows and seats would have made it more comfortable."
Cons: "The seats could have been a little more comfortable, the lumbar could have been a bit more stiff for lower back support, the arm rest up and down function did not work, and a little more space between rows and seats would have made it more comfortable. The bathroom was too narrow."
Cons: "I really wish you guys told me that in permium seating that the snacks you guys offer had nuts. You guys up sold me by telling me how much I'm going to enjoy the free drinks and snacks on the phone. So I said screw these people seemed nice and not pushy. Very upset that this wasn't giving to me."
Pros: "The Crew from check in to flight was amazing! Service with a Big huge smile."
Cons: "Nothing to dislike."
Cons: "Delayed. Flue season folks. If your sick just don’t travel!"
Pros: "Leg room seems a bit more spacious than other flights. Very comfortable. Nice experience."
Pros: "I missed my initial flight to Portland and people with Alaska immediately booked me for the next flight out. It was incredibly reassuring to have their help and patience. Even when there was a mixup with seating, the stewardesses took care of me and made sure I had a seat. Thank you Alaska, you made it right."
Pros: "Had the chance to watch interactions with boarding attendants and other passengers and flight crew. Was always very informative and friendly to passengers, flight crew and ground crew and always seemed informed on what was going on. Flight was great and stewardess' were super friendly and helpful."
Cons: "N/A"
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: "The crew were very friendly, and gave the kids extra cookies!"
Very efficient and effective. Fight crew and captain did a good job given the weather delays and turbulence…
Pros: "We've always enjoyed flying Delta and this trip had been just as nice as the previous ones we have taken through this airline."
Cons: "Our stewardess/stewards seem to be incredibly cranky on this trip and very unapproachable. They must have been having an "off" day I guess."
Cons: "Everything was great! Would love to be a loyal Delta passenger. I wish the prices were more competitive. Willing to pay more for the quality of experience but Delta always seems sky high!"
Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"
Pros: "Delta flight took extra precaution to keep all passengers safe before during and after the flight. They communicate effectively during the flight. I will be flying Delta again and again."
Cons: "The trip was great"
Pros: "Nothing, the flight was canceled without a refund. I highly recommend canceling all business with kiwi in the future."
Cons: "My flight could have occurred or I could have been refunded."
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Pros: "Crew was super amazing and friendly! Very good service also!"
Cons: "No seat back entertainment.."
Pros: "Super friendly and helpful with connections."
Cons: "The music on the plane was a bit much. Lol"
Cons: "Really felt happy on time touch down nice journey with delta"
Pros: "Onboarding was easy and smooth. The plane was clean and the seats were comfortable. WiFi easily connected, too. Much better than expected for a budget airline."
Cons: "Nothing."
Pros: "Nothing. Delayed for 4 hours. No time change updates were ever provided at the airport. No communications provided as to why our flight was delayed. No other options given. No food or drink vouchers given & of course, no discounts provided for future travel. Not that would EVER fly Sun Country again"
Cons: "Communication and updates. At the very least, food and drink vouchers. 4 hours is a LONG time to be delayed. Extra points had the airline reimbursed their $40 ONE WAY bag fee regardless whether it’s a carry on or checked luggage."
Pros: "The crew was great!"
Cons: "I had to take a bus from my gate to the plane from the new D21-26 gates."
Cons: "It was delayed 3 hours due to rain that lasted about 30 minutes"
Pros: "I got to change my seat"
Cons: "The flight attendants were rude. Our flight was delayed and we were not updated nor given a reason as to why."
Pros: "Kayak is super easy to use and get the cheapest flights."
Cons: "The crew was rude and not useful at all. Poor customer service."
Pros: "Boarding process is good. Probably a little faster with fewer carry-ons."
Cons: "I get so angry every time they introduce a new fee. You pay a fee now for carry-ons because it's slowing down the boarding process? That's only because you started charging a fee for checked bags! And every single seat option costs money? This is ridiculous! I do whatever I can to fly Southwest and get upset every time I have to fly one of these fee-for-everything airlines. Why not take crappy Spirit airlines at this point? And the seats feel smaller every time. I'm only 5'7" but my knees are against the seat in front of me. My husband is 6'8" and has no choice but to pay another crazy fee to have a couple more inches of space."
Pros: "The crew was really nice"
Cons: "The flight was very bumpy and the landing was horrible."
Cons: "The flight did not leave on time into Las Vegas. Sun country had no update until the flight departed the gate"
Pros: "Employees were fairly nice. The ride wasn’t too bumpy."
Cons: "Nothing in particular. The airlines have reduced service to such a barebones minimum that it’s difficult to feel anything about the process."
Cons: "Terrible logistics. Stuck on tarmac because they couldn’t clear the previous plane out of the gate. Fellow passengers missed their connecting flights."
Cons: "Canceled flight caused me to remain in a hotel for another day. Confusing check in. No one to help. Machines broken. Unable to disembark from the plane. Bad logistics all the way around."
This is a very short flight, so there actually wasn't any food or entertainment onboard. Although the pilot had warned of turbulence, the flight actually was quite smooth, especially compared to the VERY turbulent FAT-CHI leg we had just endured.
Pros: "Flight was earlier than scheduled. Crew was good."
Cons: "Nothing. The flight was 30 min. No complaints except for the guy who didn't wear his mask."
Cons: "Nothing--everything was great--perhaps the best service I've ever received."
Pros: "Knowing that the pilot takes out safety seriously is to be commended. Thank you"
Cons: "Not have a breakdown would be nice but I know that breakdowns are unexpected and it’s better to be safe than sorry with our safety. So thank you"
Pros: "Flight was cancelled after multiple delays & I changed to United."
Cons: "Stop delaying & canceling flights, especially last minute"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Cons: "4 hour plane availability delay - of course planned on weather but not planning"
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "Flight was quick and easy"
Cons: "Seats are small. Luckily the flight is short bit for anything longer than one hour I do not recommend this aircraft"
Pros: "Flights were delayed due to hydraulics issues, they got it fixed, turned it around quickly in Denver, made up time in the air, and got us in 20m early."
Cons: "Not sure why they add basic economy passengers to middle seats between others when there are open rows in the back. Would seem like they could set up the system to assign people to seats in the aisle/window first and then start putting them in the middle. We all moved before takeoff, but it would make things quicker and easier if they assigned seats in a more logical way."
Cons: "The internet connection was terrible i was not able to see anything that was being offered"
Pros: "Love the movies available on the United app"
Cons: "The A/C was blowing ice cubes at me, which wasn't the worst because it was pretty warm yesterday, but still it was less than ideal."
Pros: "The crew made the best out of it and thankfully it’s an extremely short flight."
Cons: "A 20 minute flight was delayed for 2.5 hrs. United did a terrible job with notifying passengers, just simply bumped out departure in 15 min increments. Original excuse was inbound delay, although plane was there for 6 hrs already. Passenger soiled himself in cabin and there was no ventilation."
Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "Friendly service"
Cons: "Cramped seating in basic economy, the upgrade seating wasn’t much better"
Pros: "The crew was very good."
Cons: "The gates were backed up due to cancellations and weather. Missed flights, lost luggage and some very angry people."
Pros: "Free snacks they gave us for the 6 hours delays."
Cons: "Everything, the delayed no one knew what was going on. It was also expensive and not as comfortable as other plans"
Pros: "Nothing at all!!! That should really tell you something!"
Cons: "The staff were rude, abrasive, ignored several passengers that were trying to get her attention before take off as 2 overhead bins were wide open and full to the brim. She of course was too busy playing on her cell phone in the back of the plane and ignored/silenced the passenger call button. They were so loud when people were sleeping, yelling ‘trash please’ every 5 minutes, we are not stupid, we can see what you are doing and if we have trash, we will give it to you - so please STOP disturbing my peace and let me bloody sleep!!!! I was never offered any food or drink during the entire flight, not even when I was awake - other airline attendants are more observant and come back and ask us when we are awake if we would like anything to eat or drink. So essentially that was 7 hours with nothing after having paid a little over $700 for what was seemingly the WORST transatlantic flight I’ve ever taken. I travel back and forth often, because I’m a dual national, but I will stick to BA or Virgin Atlantic - the planes and service are far superior to this pile of turd that goes by the name of United. There were no charging facilities (power outlet or USB port) and the TVs had such horrendous resolution that you would get a headache from having to squint at the screen."
