Airline reviews
I like the leg room. Coffee was so bad that it gave me stomach pain.
I like the leg room. Coffee was so bad that it gave me stomach pain.
Cons: "Better business class seating, better food and in seat entertainment as it isn’t enjoyable watching movies on an iPhone."
Pros: "Alaska airlines staff from checking in to flying set the bar in service standards. I have never been disappointed with their professionalism and will continue to use their services exclusively when I can."
Cons: "Nothing."
Pros: "The flight attendant was so amazing and observant that she noticed myself and classmates all wearing our alma maters sweatshirt and gave us the loveliest a shout out!! We were headed for our college reunion and had unintentionally been on the same flight. That was so much fun!!"
Cons: "Free headphones"
Pros: "Smooth flight, easy on and off."
Cons: "Staff could have paid a little more attention to what the were doing. Asked 3 times for apple juice and got orange juice. By time I realized what he had given me, he was gone ☹️"
Pros: "Kind crew and comfy seats."
Cons: "The seats were too compact, and the water tasted funny. Also IAD is not well equipped for snow."
Pros: "The crew was very good, caring and concerned."
Cons: "I don't think anything, this was another amazing flight with Alasks"
Cons: "More plentiful food selections? Everything served had dairy which I can’t do."
Pros: "Lots of entertainment options"
Cons: "Need a snack on a six-hour flight. Also, didn't receive drink service until a couple of hours in and was only served about 1/4 cup worth of soda. Disappointing"
Cons: "delayed leaving, delayed arriving, sat on tarmac on both ends..."
Pros: "Crew were great, loved having spare seats....Just a very welcoming flight."
Cons: "My screen on the Nashville to LA wouldn't let me watch the movie I wanted too but everything else was great. Glad they were there to get me home to Australia when other airlines weren't!"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."
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."
Cons: "There was huge issues with our original plane and the lady at the desk was horrible with communication to all the passengers waiting for the flight updates. The one time I finally asked her if there was any updates, after almost 1.5 hours of delay and waiting, she took a very rude and snappy tone."
Pros: "The flight attendant from IAD to MSP called Bernadette was wonderful!"
Pros: "Flight was smooth, arrived early..crew was prompt and courteous."
Pros: "Crew and entertainment options were great."
Cons: "Cabin was very loud, with jet engine noise. Could not block it out. Seats were not comfortable."
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: "Nothing. Worst flight I’ve ever taken."
Cons: "We were on the tarmac for 3.5 hours with little communication or apology. The seats were very uncomfortable. Terrible turbulence. Not even a complimentary soda for all of this. I will never fly Allegiant ever again."
Pros: "Easy boarding"
Cons: "Half the flight didn't wear masks, crew didn't bother to enforce."
Pros: "Crew was Aamazzing! Went above and beyond even to sit with one of kids while I used restroom, put my kids at ease, went above and beyond to make sure at such a tender age that they were okay! Made me very happy with allegiant and happy that I chose them!"
Cons: "It’d be cool to see more inflight services some day? As in maybe WiFi at a cost or TVs, seat recliner"
Cons: "I had problems with baggage and Allegiant staff at the airport were very unhelpful."
Cons: "I would have liked to have a drink of water for free!!"
Cons: "More space under the seat in front of me for my carryon"
Pros: "Quick direct flight that wasn't packed"
Cons: "The woman that checked my bag kept calling me "sir" and after I corrected her a second time she rolled her eyes and said "oh, I don't even look up" I am not a man. For Pete's sake pay attention."
Pros: "The boarding wasn’t smooth, there were 3 women at the podium listing zones and it was very mumbled and low, quite hard to hear despite the small area dedicated to Allegiant passengers."
Cons: "The women at the podium listing flights could have been friendlier and more customer service oriented... there was a lot of mumbling into the speaker for boarding ... and the person kept giggling into the mic. Once past boarding, everything was great !"
Cons: "The seats were a bit cramped but I suppose most are these days"
Cons: "I bought a flight that I had to end up cancelling - when I called to cancel - within the 24 hour period, they would not let me cancel despite text on my confirmation saying that there would be a free cancellation within the 24 hours. Extremely annoyed that there was a blatant miscommunication. I did not end up going on the flight but was unable to get a refund which seems ridiculous given that there was text on the website explicitly saying this was their policy."
Cons: "More legroom and monitors in the seat back like Jetblue."
Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"
Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"
Pros: "Crew was helpful. Flight was on time. Luggage was provided in a timely manner."
Cons: "Underseat space for center seats is not adequate for two seats. One the the entertainment screens required multiple resets throughout the flight."
Cons: "My tray table was dirty. It had crumbs on it. The flight was on time which was awesome."
Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."
Cons: "We landed early but the plane was late 50 minutes into gate. Plane went pst our gate twice, just driving around the terminal."
Cons: "I'm expecting more from AA. We were delayed for 2.5 hr since we didn't have a pilot !!!!!"
Pros: "Service was wonderful and flight pretty much smooth for the 6;5 hour ride back to Seattle. I do enjoy taking American Airlines."
Cons: "Had a 350 pound gentleman in the seat in front of me and had he had no idea of how stressed I was when he would try to adjust his to go back further."
Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."
Pros: "Got to San Antonio finally"
Cons: "Not having maintenance issues on the same flight from the prior flight to our airport then having more maintenance issues prior to leaving."
Cons: "Wholly inaccurate and frankly FALSE information about baggage policies and seating. This was advertised and linked to the baggage policy of Austrian Airlines. I learned at the airport that I would be charged for bags, by United. I am inclined to never use Kayak, Austrian, or United ever again."
Cons: "The delay was horrible and the captain said it was because they needed extra sleep. I found this offensive as i was trying to complete a very long trip and was exhausted."
Pros: "Once on board, everything was great."
Cons: "The gate was crowded, and it was difficult to hear gate announcements. Everyone was confused unless they'd been there before. The gate assignment is confusing to everyone considering you go through the same door."
Pros: "We landed in NYC -- although it was first announced as Dulles."
Cons: "This flight was on Canadian Air under the auspices of United. I was not allowed into the United Club lounge despite the fact that I had business class ticket. I was informed that a business class ticket isn't sufficient for using the lounge when flying domestic. It is only good when flying international. They call that customer service. I generally avoid domestic airlines because of the customer service. The flight attendants were not happy to serve you. It's a small flight but they didn't even offer a snack -- you had to ask for it. And then they brought over a small basket with nuts, chips, candy bars, and a muffin. I took a muffin and it stuck to the roof of my mouth -- very poor quality. When I asked for a snack the flight attendant replied cocktail or soft drink never saying whether or not a snack was available.. She said this a couple of times before I could repeat that I wanted a snack to which she replied you want something to drink with that. I've been on many short flights in Asia and they will deliver a full meal and you don't have to ask for it. There was no entertainment but United did send an email explaining how I could purchase entertainment to play on my own device."
Cons: "The flight was delayed by five hours due to a mechanical problem with the plane. Little information was provided by United. Frustrating experience."
Pros: "Quick flight, faster than schedule. Flight attendant was good."
Cons: "Absolutely no leg room or arm space in the seats on US express jets. If the flight were longer than an hour it would make for an absolutely miserable experience."
Cons: "The prior flight was delayed because after taxing, a crew wanted to remove an uncooperative passenger and went back to the gait. Subsequently, we arrived in Washington DC with only a few minutes before our next flight Albany was scheduled to leave. Because we had to do check our carry-on bags, we were 5 minutes later to the gait where the airline refused to wait for us to board although another passenger who did not have to wait for her bag was able to board the flight Albany. We therefore had to take a shuttle to Reagan international Airport, fly on a different airline to Hartford Connecticut, rent a car and drive 2 hours to finally reach our destination in Albany."
Cons: "Because of missed connection I had to go from Dulles to Reagan airport"
Cons: "It wasn't until AFTER everyone boarded the plane at 9:45 that they informed us that " they only had until midnight to reboot their system so they HAVE to do it RIGHT THEN" then they informed us twice that it was "stuck" and "not working" our plane was supposed to land at 11:18 and we didn't take off until 11:00. My husband has work at 5:30 in the morning as well as my brother who was supposed to pick us up and they are in the navy so being late isn't an option. My brother could no longer pick us up due to the fact that we did t get our luggage until 1 in the morning and he has work in a few hours so we had to wait for a taxi and pay a buttload to get home in Virginia Beach. NOT PLEASED!!"
