Cons: "Nothing"
Pros: "Free movies"
Cons: "First time on Alaska air, on my departure got delayed for 8hrs, then that one we end up deplaning. On my arrival, the plane got delayed again. It’s not a good experience all and all"
Cons: "I was not notified that my card was declined and this caused a ton of delays"
Pros: "Fast flight"
Cons: "Seats were a little uncomfortable. The boarding process took a while."
Pros: "Crew was friendly and fun. Seats were roomy with plenty of leg room."
Cons: "No soap in bathroom stall. Told crew who tried to correct it but it was broken. Boo..."
Pros: "Half of the flight was empty. I asked of I could move to the row behind. I was told that was premium seating and I didn’t pay for that. I didn’t appreciate being addressed like that. And did ot really matter when nonoe is sitting there or plenty of other seats."
Cons: "She could have just let me sit there. I should have been told that the seat didn’t recline when the ticket was pirchase."
Pros: "I always enjoy Alaska but this was another level. I was horribly late and still processing at security with 10mins until take off and the guy at the gate called me to see where I was - gave me mins to make it - which I did - just.. I was traveling to San Diego to meet my family for the weekend - I would’ve been in severe trouble had I missed the flight. Thanks Alaska!!"
Cons: "We were to leave the airport at 3pm, but didn't leave until 5pm. So we ended up arriving at 6:30 instead of 4:30. Not happy at all"
Pros: "Friendly staff"
Cons: "-Delayed departure (almost 2 hrs). -Gate change with missing flight info at the new gate screen until the last minute. Lots of confused passengers asking if the gate was correct due to the flight leaving late."
Cons: "My monitor isn’t really working after rebooted. And the audio hole wasn’t tight enough"
Pros: "Terrible seats! It keeps getting worse."
Cons: "Timing of leaving the airport! It was delayed and I missed my international flight"
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"
Pros: "Flew us safely home."
Cons: "We waiting on the runway for over a long period."
Pros: "Food was unexpectedly good."
Cons: "The flight was delayed for 40 minutes. We could hardly catch connecting flight"
Pros: "Food was good, boarding was fast and efficient"
Cons: "Smallest seats I’ve seen in a while. Very uncomfortable. Still haven’t announced baggage carousel but that’s jfk for ya. WiFi didn’t work on flight either."
Pros: "Good movies and tv selection. Seat next to me was empty, so that was great."
Cons: "Nothing"
Pros: "Call back service was best part."
Cons: "Booked ticket through venture card points. This meant that the email address and phone number to contact us in the event of changes was mediocre information. I was informed from Tripit that the flight was delayed, not by Delta. Reservation personnel took logical course of action to find new flight for connection that we could make because of delayed initial flight. I would recommend that they first see if there is an earlier initial flight that the customer could make, then look at finding later connecting flights. We found out about delay 8 hours prior, so we had plenty of time to get to the airport earlier. Total delay required me to take additional day off of work."
Pros: "The crew are very friendly, positive and have good sense of humor."
Cons: "The flight got delayed badly"
Pros: "Everyone was really nice and responsive."
Cons: "Seats are a little older. Not as comfortable as other flights. But not bad."
Pros: "The crew did an excellent, professional job."
Cons: "There were problems with arrival at the gate necessitating delay and 3 gate changes for connecting flight. This was not fault of American but due to a plane breaking down at the original gate at LAX causing our plane to be rerouted to a different gate."
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: "They lost my luggage and have not been helpful in trying to locate it!!"
Pros: "The flights were on time and the staff was very friendly."
Cons: "Flight attendendant were unfriendly,she missed my dinner ,I had to call her so she bring my dinner!"
Cons: "My flight was canceled and rebooked overnight, then delayed 2-3x. This wasn’t all the airline’s fault, but nevertheless, it was a very mediocre experience."
Pros: "Food was delicious! Crew was very nice and friendly and plane was very clean."
Pros: "The UA Private Screening feature was unavailable on tipis overnight flight bah."
Cons: "Getting to San Francisco flight was canceled, make a line for 3.30 hours to let us know what they were going to do with us, they give the place to go at 3 a.m with not directions were to take a bus , later someone come and told us the bus stop running at that time and I have to go upstairs to take a taxi, I was alone and not use to be alone at that time never in my live I had to pretend I was afraid. Of course the hotel only take you until 12pm so I spend so many hours in the airport waiting for re ticketing they told us to be at 6pm we wait and I got my ticket leaving at 9.45pm but the crew come one hour and half late. From Panama to Lima flight was late . I had a conference very important to be Saturday morning, I lost my investment and relationships with the company I was going to start a business there excuse was they couldn’t relay on my punctuality, honestly. I got there more than a day and half LATE. If you ask me how was my trip I will tell you horrible and I can’t recommend anybody, this company doesn’t have any personality at all"
Cons: "My 10:00 p.m. flight was canceled so I had to spend the night trying to sleep in the airport. Have you ever had to do that? Not fun."
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"
Cons: "12+ hour flight with no working outlet to charge phone or headphones. When I asked to move to a seat that had a charger, they basically said no - even though there were about 20 open seats in the next "economy class" level. So for 6 hours, after my phone died, I basically stared at the wall and then had no phone to assist with my directions or hotel reservations once we landed. Food was not good. Plane was old, and had a few random screens playing a movie that kept freezing and had to be restarted."
Cons: "Flight was canceled. Rescheduled on next morning on economy class even though the original tickets booked for business class. No hotel, food voucher, etc. were provided blamed on the weather condition even though the bad weather was 1-2 days ago, and on the day of departure it was air traffic control problems which was stated in cancellation email."
Pros: "American Airlines"
Cons: "Dear United Airlines, It is my dearest wish that reading the following inflicts upon you at least a fraction of the stress, frustration, and pain that I have been through traveling with you today- you absolutely abhorrent excuse for a company. Due to your incomparable incompetence my arrival was inexcusably delayed almost 12 hours. An account follows: For a company who's customer service is already hanging by a very thin thread you would think that you would be doing everything to make your flights as smooth and pleasant as possible. Shall I elaborate on the utter frustration and boredom of being trapped in the San Francisco airport facing not one, not two, but what became SEVEN delays? Delays that have been caused by runway maintenance- a condition which someone in your company would have known about well before I got to the airport and that you simply did not plan for. A almost FOUR HOUR delay that could have been easily avoided if you just had things together and scheduled your planes around the affected runways. And let's not forget the additional delay caused when your flight crew simply couldn't be found to come to the gate so we could start getting underway! But no, I think the absolutely outstanding quintessential experience that defines flying with United airlines is this: After the above delays myself and my fellow passengers were finally able to board our flight- only to be told by the captain that there would be another brief delay while we waited for ANOTHER crew member because one of the pilots was near the end of their union hours. We sit on the plane stuck for another 20 minuets or so, only to be told they can't find anyone, and can we please get off the plane because our WHOLE FLIGHT is CANCELED. The kiosk I get to try and fix this is uncrowded but understaffed and run by clearly undertrained employees. The ones I'm dealing with keep having to ask each other for help, and give advice/plans that contradict one another. One of theme even takes what seems to be a personal call while 'assisting' me. When I finally get ahold of a supervisor I have to plead to get the next flight out of this godforsaken place, which I am reluctantly given as its with one of your competitors. Talking with other customer and airport staff is sounds very much like you are delaying/canceling flights for your own personal gain or at least not correcting flights around the situation to squeeze more money from the situation) it becomes quite clear that you are not only still incapable of accepting any real measure of accountability but entirely disgracefully unorganized. Almost 12 hours later I do finally make it home- thanks to American Airlines. Only to have the utter displeasure of one last interaction with United wherein when I pick up my bag your employees insist that I was delayed due to the weather and it wasn't your fault. It was entirely absolutely your fault."
Pros: "Noting"
Cons: "Bought the ticket from Lufthansa but the operator was United. Although it was known by the operator that there is a delay already at check-in, passengers where notified only at the gate. Delay was so long that most passengers would miss their connection. After standing an hour in line at the gate to book alternate connection, counter was closed and we were directed to another 10 min walk away. After another 1.5 hours without reaching a representative we had to rush back to the gate to board. In Frankfurt had to stay in standby for the next alternative flight. Luggage was delayed in the US for 2 more days."
Pros: "The view and legroom was nice."
Cons: "I collect disability each month so I am on a very tight budget. The Spanish speaking woman that pushed my wheelchair told me that I can bring my water bottles full of water through the metal detectors. I asked if she could take me somewhere to pour them out and refill them on the other side. They threw them away at the metal detector. So I had to buy a new bottle for my medicine that I have to take. You would think she would have got it by me carrying these bottles around but nope. She actually said to me that I can give her gratuity now if I wanted. I gave her $1. She then replied in a sarcastic voice " Thankyou you are soooo generous. I don't like feeling obligated to tip somebody because I am disabled and have a bullet in my head."
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: "the price"
Cons: "the stressful environment with screaming babies/toddlers (six of them) the whole way non-stop"
Cons: "My flight from SFO to Denver was canceled and I missed this flight. Had to pay more money for a mnother flight."
Cons: "Flight was delayed 6 hrs while other flights to Denver kept taking off"
Pros: "Low fare! I pack light, so I could fit everything I need into a "personal item" and saved on bags. Boarding went pretty smoothly."
Cons: "Seats do not recline! Bad news on my redeye flight. There were 4 dogs on this plane that I saw. Possibly more. Is there a limit to allergen producing animals on one plane?"
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: "They oversold the flight and bumped us from it. We didn't make it home for the holidays."
Pros: "Clean, friendly staff."
Cons: "Seats did not recline, so it was impossible to rest during this long, middle of the night flight. Misled about cost of carry-on."
Pros: "Flight was good and landing smooth."
Cons: "No beverages or snacks were offered. The flight was a late night flight and there was no where refreshments or beverages could be purchased, hence I was forced to fast for 6 hours."
