Flight delayed over two hours, very little communication from staff then had to wait 2.25 hrs to clear passport control. Had arrangements for evening ruined as a result.
Flight delayed over two hours, very little communication from staff then had to wait 2.25 hrs to clear passport control. Had arrangements for evening ruined as a result.
Pros: "Crew were super friendly and helpful. Food was delicious, comfortable seats, great selection of entertainment."
Cons: "Cheaper baggage rates"
Pros: "Virgin Atlantic is the best airline I’ve ever flown on internationally. The service is wonderful, from check in to inflight service. Everything went as planned. The food and drinks on board are free and they are an abundance of snacks, much more than we dreamed. The flight attendants are excellent"
Cons: "No. Keep up the good work!"
Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."
Cons: "There is no entertainment, not really required on a short flight but nice when offered."
Pros: "As usual, punctual flight with friendly crew."
Cons: "Pity the wifi in international flights isn't complementary (or at least a basic connection like on domestic flights)."
Pros: "Food was delicious, consistent timely service and excellent entertainment options onboard. The flight was an hour early!"
Pros: "The flight crew was phenomenal, especially Daniella. Somehow we wound up with seats right next to the bathroom door, which would have been a pretty uncomfortable situation for a variety of reasons, but the flight wasn't full, and she helped us find a suitable place to sit. Also, my wife and I usually take our tea with honey vs. milk and sugar. Even though honey is usually one of the options for tea, she found a way to accommodate our request. The lunch meals were the best I can remember in a long time on an airline flight. They might have been the best I've ever had. The chicken curry was authentic, flavorful and spicy. Frankly my outbound flight had problems. My luggage got damaged. The transfer experience in Manchester left a LOT to be desired. I wasn't planning to use Virgin Atlantic again, but this flight crew (Daniella especially) redeemed Virgin Atlantic. They were attentive, pleasant, diligent."
Cons: "Only thing I didn't like about this flight was the boarding area. Once you get into that the area, you don't really have access to appetizing food (only vending machines) or even restrooms. That's one thing that could be improved."
Pros: "Amenities"
Cons: "Bed was incredibly uncomfortable in first class. It was like sleeping on the floor. People talking loudly in the bar late into the night, which made it even harder to sleep. Didn’t sleep a wink on this 10 hour flight."
Cons: "The flight change the gate number immediately so I missed my flight"
Pros: "one of the worst airlines I have traveled on. Will never fly air lingus in my life."
Pros: "The staff are always lovley"
Cons: "They lost my bags and 5 days later I still don’t have them.. traveling alone with a baby for Christmas.. all my gifts were in that bag so Christmas is a bit of a loss.. I find it way to difficult to get refunded or reimbursed for my loss"
Pros: "seats were uncomfortable and why dont the armrests go fully up? it made sleeping difficult"
Pros: "The crew was nice."
Cons: "We thought we were flying British Airlines. The seats were extremely uncomfortable. Foodcwss not good"
Cons: "Late boarding and had to wait 20 to 25 min in tge plane before tge doors of the plane finally opened."
Cons: "Had to cancel. Impossible to workout fair flight change for outgoing flight only - caused cancellation and repurchase return leg for no reason but greed, as Aer Lingus did not impose this. After multiple long waiting periods on the phone to work this out no one ever picked up. We will never book through Kayak/JustFly again."
Pros: "Aer Lingus service was good and efficient from check-in to arriving."
Cons: "Little time in Dublin to get to our connecting flight to Lyon. Security check was understaffed with long queues."
Cons: "The flight was delayed by two hours. The one of the crew members - I think his name was Gerry - was quite rude and negligent: for example he did not give an infant life vest to our baby saying that it won't be needed..."
Cons: "The flight attendants were helpful enough, but they did not offer as many drinks as I like. Breakfast was only coffee, tea or water. No juice at all."
Pros: "Boarding was smooth. The staff was extremely friendly. The games on the video screen weren't bad."
Cons: "There was a technical problem with the plane at our gate when we landed, so we were on the tarmac for an hour waiting for a gate to open. Video choices were limited, and Internet was extremely overpriced."
Pros: "Nothing."
Cons: "I'm still at Heathrow 12 hours later. I never made it to Oslo."
Cons: "Missing one suitcase and it will be delivered a day late supposedly"
Cons: "Club World is a super dated product. The tech is old and you are uncomfortably close to your neighbors. Also even when you buy a business class ticket British Airways makes you pay to reserve a seat in advance if you don’t have status with them. That feels over the top for a premium customer."
Cons: "BA is löst. This whole experience for a first class flight was a joke. SF no Lounge, food terrible, london lounge max BC level. LH 2x better, they need change"
Cons: "They did not give the gat no till the very end and the s cueing check was horrible when carrying a baby"
Pros: "Nothing"
Cons: "We waited in the plane for 5 hours and ended with a cancelled flight. We were rebooked out of Oakland the next day. Missed an entire day in Rome for our honeymoon, lost a night at a hotel, and lost money on a tour."
Pros: "The food, the staff and the free movie on the airplane."
Cons: "My American partner's passport expires 2 months after our return to the US. Unfortunately, the French issued a year ago the following rule: to enter France, the foreign passport must not expire at least 3 months after the return date. British Airways let us fly to London, explaining this to us, how it would be on us if there were problems further down, and that we would have to get our luggage in London. We chose to fly thinking it would be OK, we had listened to an online person who had had the same problem and the French later told him they would have let him in, also I am myself a dual citizen of France and the US, plus I am autistic, an invisible disability (in my case) that makes it impossible for me to travel alone. I usually do not even say it since not much is understood -by those who do not have it- on how to accommodate it However in London BA did not allow my partner to go on. Due to the fact yesterday was Easter Monday, the American consulate in London was closed. We have spent the night in a nearby motel and now, the next day, I am waiting alone back at the airport with our 2 large suitcases while my partner is at the American consulate. We are poor, do not have phone, currency or charger for England, and I do not do well with stress, so it is difficult. Now we cannot easily reach one another. We hope to be able to fly on a standby basis (that's what BA told us we could hopefully do) later today. Sorry for this long letter, I hope it does not bore whoever reads it (if it is even read :). Anne-Laure"
Pros: "I like that we didn't crash"
Cons: "They lost my and 5 other persons luggage! British Airways sucks!"
Pros: "Only one layover in London"
Cons: "Emirates, Etihad flights I thought were a bit newer and better in terms of comfort and entertainment with more charging ports etc"
Pros: "Crew were good , food was ok."
Cons: "Flight delayed again so both flights to USA and return were delayed... not a great experience . Entertainment took a cou0le of hours to sort, they had to keep resetting it"
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."
