Get our, as a group, skis on time to their destination. Have more attendants checking people in. There was only one. The line was a block long :( . Also flight change with 5-hour delay

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

They delayed flight because lack of staff then missed connection. Never flying with kayak or weather

Very good over all , would have been nice to have entertainment on the flight

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

Service is pretty good. Sandwiches have to be purchased but I’ve bought my own food. Seat was comfortable and various movies to chose from.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!

My plane was cancelled and had to be rebook for the evening was not happy.

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

The flight was delayed several times, however , they kept me well informed with enough advance warning that I had not left home yet

I can't say as it was cancelled and rerouted to Toronto. I had an unexpected 10 hour layover there. A new delay every hour, Flights overbooked. Misinformation given from registration to help desks. A long exhausting day of travel on the way home.

Very friendly staff. Good seats on a quick flight. Right on time.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

All was good. I would have preferred free drinks besides water (coffee/tea).

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

Two things to note here. First, Lufthansa separated me from my small children. Apparently you need to pay extra to ensure that your children are not abandoned. This is different from KLM-Air France, where children sit with their parents automatically, and I usually fly KLM-Air France. I didn't realize Lufthansa was different on this score and is willing to leverage the wellbeing of small children to generate more revenue. Second, my flight arrived 3 hours and 54 minutes late, so I am entitled to financial compensation as per EU passenger rights regulation. From other aspects of Lufthansa's behavior during this trip, I expect that their approach to this is to start a war of attrition with their passengers to avoid giving compensation as much as possible - again, very differently from KLM-Air France. But we'll see, maybe I'll be pleasantly surprised.

Horrible. My gate did not get updated with our boarding pass. We didn’t receive any communication regarding gate change. Also not enough time was given in between flights. Zero consideration for people who are coming from abroad and have to get through customs and US border patrol

Not that great. There were no entertainment screens, internet, or any way to track the flight path. The seats were fixed in order not to recline at all. The crew and the staff at the check-in counters were the only nice thing.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

my flight was canceled and rescheduled for two days later

They oversold and down graded me from Premium economy to coach. 75-pound compensation is insufficient if you chose a particular class. I get dehydrated and severe Charley Horse cramps. I requested a bottle of water, even half even less… but no- “We are only allowed to give water by the glass. Nonsense. Lastly, their planes now have a fixed barrier between seats. So even if your entire row is empty, you are confined to just your space. Lastly, London now requires a transit visa for $30 for US citizens. Never travel through London again

I love British Airlines but I think it’s time for a change.My seat was occupied by very large passengers sitting next to me,I felt very uncomfortable and very bad.I’m sorry but I have to say it.

We had to pay extra for seats and bags (even for an international flight). I paid for extra comfort seats, but it was under an overhead bin that the crew used for supplies. I paid extra hoping to get sleep. We were constantly woken up by the crew opening and closing the bins. Our seat shouldn't be considered extra comfort. We paid significantly more than the rest of the cabin for these seats

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful
