Pros: "The pilot went around to passengers and apologized foe delay."
Cons: "3 plus hours of delay????"
Pros: "Seats were very comfortable and they provided free movies with a seat console for a 2-hour flight. Great!"
Cons: "Nothing"
Pros: "Fast flight"
Cons: "Seats were a little uncomfortable. The boarding process took a while."
Cons: "Dirty cabin, dirty glass, worn out carpet, seats falling apart, filthy privacy crew drapes. The CEO needs to be more hands on and do random inspections."
Pros: "Smooth ride"
Cons: "Left a little late so our flight was a bit late landing in return"
Pros: "Great entertainment system, great selection of movies. Comfortable and well kept up plane."
Cons: "Controls for entertainment system were often broken. Flight boarded late. Few vegan snacks available."
Pros: "Check in was easy. I love the way you can order from the screen infront of your seat food and drinks. In addition; you can select movies. Everyone was very nice and professional. I usually fly with jetBlue, but today I was so impressed I am considering changing."
Cons: "If there was a less than one star that is what they deserve. SFO flight was late. They gave away my seat on my connection to Kalispell. They basically blamed me for being late and not being there on time. Two others from my flight were allowed to make the connection but told me that they gave my seat away because I was late. We all showed up at the same time from the late flight. I talked to 3 people including customer service and did not get a single “I’m Sorry”. Do they not communicate with each other when a flight is late and they have passengers for connections running late? They told me they don’t talk. The best they can do is put me standby for 9:30 flight and if I cannot get on that flight I have to wait until morning. My daughter is in a competition tomorrow morning and thanks to Alaska Airlines I’m going to miss it. I’m sitting here writing this review, paying for a dinner I should not be paying for and probably searching out a hotel room until morning when I can catch a flight. Unbelievable the lack of empathy."
Pros: "not too much"
Cons: "We made it to the gate with a good 10 minutes before take off. They did not call our names on the overhead because we were nearby the gate. But when we approached them at the gate counter, I heard the radio saying that our flight was pushing back. WTF?? Luckily they were able to get us on the next flight an hour later. But still, not impressed."
Cons: "I was rerouted at the last minute to another airport. Late taking off. No food on board. They were sold out on another flight."
Pros: "Crew was solid."
Cons: "Don’t change my seat. Not on time. No food. Luggage with legally checked firearm sent to the wrong airport."
Cons: "Crew was abrasive and put off by people asking for service. Monitors had to be rebooted 3 times. Ran out of water and snacks."
Pros: "Decent entertainment options and snack offerings."
Cons: "Last 6-8 rows were vacant and for some reason Someone was still seated directly next to me. Why on earth the flight attendants (otherwise great) didn’t make an announcement that there was no need to share a row and encourage people to spread out is beyond me. I mean this is the only flight I can remember in a decade that wasn’t nearly or fully booked, you’d think they’d emphasize that. Instead I got to be trapped like it was a full flight next to a guy with no concept of personal space."
Pros: "Smooth, efficient and timely."
Cons: "Seats weren’t assigned until at the gate even though checked in 18 hours before. Bag drop was horrible. No self service. Was inline for about 45 minutes."
Pros: "delayed, switched to another flight, delayed 3 times...crossed the border at 1am...terrible experience overall"
Cons: "everything"
Pros: "Good flight as always with Delta. Sat in economy comfort, so of course the seats was comfortable. Flight Attendants were great."
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Cons: "My monitor isn’t really working after rebooted. And the audio hole wasn’t tight enough"
Pros: "free movies on the flight"
Cons: "The check-in process at SFO airport was poorly managed."
Pros: "It was Ok. Some short delay but over all not too bad. Just didn't like the fact I always get seats next to the toilet"
Cons: "The flight comfort was very bad. The plane was extremely warm and people we beginning to feel bad. Several mentioned it and asked multiple times to have the the cabin air conditioning turned down"
Cons: "The gate agents called all boarding groups with the boarding queue extending the entire length of the jet bridge and into the terminal beyond the gate area, making us stand in line ten to fifteen minutes longer for no reason."
Cons: "It would’ve been nice if we made it to fort Meyers!"
Pros: "Nothing"
Cons: "The seat assignments based on loyalty status - rude gate agents"
Pros: "Nothing"
Cons: "Took off 40 minutes late, rude attendants, very hot on plane, no apologies from staff for being late. Worst flight in a long time."
Cons: "I could not pre-check or request different seats on the CP website. I think that this was because of issues with the website, apparently due to IT system communication between American Airlines and Cathay Pacific.......on all six flights. On the transfer in San Francisco, Customs was closed when we arrived in San Francisco and we had to haul all of our baggage from one terminal to the other. There was no direction on how to handle this issue of Customs being closed while on the flight to San Francisco. I had to explain the issue of to the CP customer service crew in SF. The CP desk and they had never heard of it. American Airlines was equally poorly trained. I will also say that while at the CP customer service, there were three young adult males that we're not busy at the time and the watched us unload the baggage carts onto the scales and conveyor and then reloaded on to the carts to push to the AA terminal. We handled the bags two additional times because the CP staff did not know what to do and how to handle it. Other passengers were confused as well."
Cons: "Flight attendendant were unfriendly,she missed my dinner ,I had to call her so she bring my dinner!"
Pros: "Smooth flight, pilots were friendly. It was a nice flight"
Cons: "We thought we were going to be flying on British Airways American Airways."
Pros: "Friendly and helpful crew."
Cons: "Not sure why American would fly a plane across the country with no electrical outlets, entertainment options, or food beyond snacks."
Pros: "Love the ability to watch films on my device by way of United WiFi"
Cons: "Better snacks"
Pros: "The fact that we actually left."
Cons: "Delayed and upset passengers. Bad breath from passengers circulating in the AC. FA we're okay nothing above and beyond."
Pros: "On time."
Cons: "Impolite gate crew, screen and wifi not working. No outlet at seat. United has successfully become Spirit's number one competitor for worst airline."
Cons: "Second mechanical delay for me on this trip with United and the plane felt very old and rickity. Extremely delayed into Seattle until 2:40am"
Pros: "Very smooth fligh and very friendly and helpful staff"
Cons: "The seats were extremely crammed and there were no movies or shows without purchase"
Pros: "United Airlines is a poor excuse for travel options. Definitely two or three levels below European owned airlines. We are fine with Alaska Airlines, but the rest of American own airline companies take a back seat."
Cons: "Nothing about this flight was enjoyable."
Pros: "I arrived safely."
Cons: "It's a zoo. It's a DIY of checking in and checking your bags in. No staff is around to help. You are on your own. Unorganized."
Cons: "Late late late. Had to run to get my connection. Not Uniteds fault though. SFO too busy. Will avoid in future."
Pros: "The flight left on time and landed on time."
Cons: "The asian mix cracker pak was horrible. Seats cramped and uncomfortable. Plane loud inside and cold."
Cons: "No wifi... with the amount you pay for the flight, seems insane you have to pay for wifi too"
Pros: "Definitely can't beat the price, especially for a non-stop flight halfway across the country. I had plenty of room in my seat even with my backpack under the seat. The drink and snack selections are pretty decent."
Cons: "Delayed to start and it took a while for all the bags to be loaded. Once we arrived it took over an hour from the time we touched down to when our bags arrived at the baggage claim. Ended up finally leaving the airport an hour and a half after the time I was originally supposed to arrive."
Cons: "Flight was delayed by almost two hours so I missed the flight from Denver to Charlotte. Because of the way this flight was sold to us and booked through Kiwi.com, there was nothing that could be done to get me on another flight. The only option was to wait for a Frontier flight which wasn't available until Monday morning. I had to book another flight on a different airline at a cost of $600."
Cons: "Negative leg room, Hugh bag fees that were not stated in the original purchase"
Pros: "They still pick up trash!!"
Cons: "New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky."
Cons: "Flight was delayed 6 hrs while other flights to Denver kept taking off"
Pros: "It didn't crash"
Cons: "The whole staff from the check in to the attendants was rude rude rude. Never again!"
Cons: "The flight was delayed and we got a notification from google, but when we called Frontier, they said it was on time. And when we reached the airport they said, its been delayed. It caused a lot of inconvenience. Very unprofessional."
Pros: "Efficient from the crowded baggage check to baggage claim. Great Job!"
Cons: "Seats don't recline, get what you pay for!"
Pros: "Flight attendants helpful and pleasant"
Cons: "Plane was filthy. Crackers, chips, etc all over the floor. Wasn't a clean spot anywhere. Unpleasant to sit for several hours with my feet in filth and to have to put my bag in it under the seat."
Cons: "Flight was cancelled 30 minutes prior to boarding with no explanation given. There were no other flights on Frontier for two days. There was one single gate agent responsible for dealing with every angry passenger. I had to rebook on a different airline for the next day, and it cost me $250 more. This was very painful, especially during the holidays."
