Airline reviews

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Did not get the seat I selected and paid for.

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

American Airlines is a mediocre airlines: they do not maintain the highest standard of cleanliness in the cabins, and the food is not well thought out. Service is not at top of mind compared to other international airlines such as Singapore Airlines, JAL or others.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

I flew Business Class. Rory, one of the Cabin stewards, was attentive, explained the menu, provided appropriate drinks. was

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

It was chaotic. It was overbooked so we didn't have seats until the end but they turned out to be good seats. The gate was at the end of the airport. We had to get busses to the tarmac and board. It just seemed chaotic. Flight was OK. Food was not so good. Lufthansa used to be such a great airline and now as it's with everything else: If you have money you get comforts but if you don't then you end up below deck with the rest of the cattle.

Welp - they boarded us appropriately...then had us sit on the plane for over two hours before cancelling the flight...which meant another night in Munich. I probably had it a little better than most as over 500 people had to be accommodated/re-booked etc. The next day I boarded the same flight (for which I had now been ticketed 3 straight days) and - with "only" an hour delay, managed to finally get home over 2 days later than scheduled. I haven't flown Lufthansa to Europe in years...and I won't be looking to do so again in the future. To be clear, though, the people I interacted with - flight crew, Service Center, check-in were all professional and courteous - management is clearly to blame for their lack of communication and unpreparedness for when things go wrong.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Seat very cramped, could not recline. No cheese with meal. Staff very helpful.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Everything. Boarding, service, food, seats, crew I'd increase the air pressure to avoid dry sinuses and after effects

Flight bumpy and aircraft old with tape over seats , it seems there is a lack of maintenance, air pipe blow off in the middle of the flight, flight attendant seemed not to be worried about it. Food got very bad over time , not only for the quality but for the quantity . Seats are very uncomfortable , entertainment not working properly.

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

Everything was good except the bathrooms were usually dirty and the trash bins in the bathrooms were full.

Better consideration for families traveling with a disabled person. They insisted each person hold their own boarding pass on their own devices and gave us a hard time accepting eight boarding passes on a single device.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Great crew, newer plane, boarding was very disorganized, I still don’t understand why airline keep boarding front to back for coach instead of back to front

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

I paid for full WIFI- it was terrible, kept being in and out could not listen to a podcast

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.
