It is great to have a nonstop flight. Might be worth paying a bit extra for it.
Verified travelerFlew with Air CanadaAug 2024
Treat this like you’re flying on a greyhound bus. Bring food. Bring a pillow. Bring entertainment. Know that you will be uncomfortable and the airline won’t care.
Verified travelerFlew with United AirlinesFeb 2024
Do your check in online because it is much more convenient.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

Lavatories broke with an hour to go. At least we were on time.

Chaotic boarding, but mostly my issues are with Toronto airport

Flight delayed by half hour, causing rush to get to connecting flight in Toronto Pearson which doesn’t have good flow for managing immigration check and connections.

Service was amazing, and the plane was comfortable even for this long haul. But they could have more movies selections. But they were still a lot to choose from.

Due to mechanical problems it was delayed causing problems the actual flight. Was fune

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

The width of the chair is very small. Not comfortable at all.

Flight delayed over three hours. Arrived into SFO during rush hour and what would have been a one hour drive home took more than 2 hours. Very poor UNITED AIRLINES!!

I found that it seems that the space for personal bags or luggage is not enough( the cabinets for personal bags or luggage over the seats) .

The Cree was BEYOND AMAZING. They were, by far, THE BEST CREW I had the pleasure of flying with. They catered to my every need, beyond friendly, and upheld the highest level of professionalism that is of Lufthansa Airlines.

service was slow and at times there was no service at all in premium plus seats. they do not care about people in premium plus

To san Francisco it was ok. From sf to Manila it was horrible

Delays happen but communication and care were very low on what ended up being a long day.

Terrible experience at the gate. Charged for carry on luggage despite them meeting the requirements for sizing.

Never been on a long haul flight that didn't have on flight entertainment. I hope the way back is better !

Seat barely reclined. Boarding took forever. Flight attendants were not very friendly

Very easy boarding. The on board snacks were not good.

They canceled the flight with no reason given they should not be in business

We had a 44 minute layover ( ??? ) to change planes for our flight to SRQ. We landed at Concourse D, and the SRQ plane was located at Concourse B, as we were told in Toronto. We got to "B4" as directed by ( Delta Help ), in less than 10 minutes, only to see the flight we booked to leave at 2:28, was showing "DEPARTED". Back to Delta Help, got an extremely obnoxious and rude clerk who gave use two options, next flight leaving 5:20, on "B12", (STANDBY). or (CONFIRMED), leaving around 8:PM, not sure of the exact time because they took our seat request and gave us another boarding pass minus the exact time. We had been waiting hours for the 5:20 flight and at the very last minute a group appeared and were allowed to board. When the "standby" folks were summoned, several were allowed to board ahead of us, even though we were there much earlier. The clerk, who gave his name as Markus, a black man with a beard, was the most arrogant. rude and condescending individual in existence. When I asked him to repeat his name he said "what did it sound like?". Had I been thinking I would have answered to me it sounded like (markasshole) which is exactly what he was. When we originally got to that gate and asked for advice, he went on and on telling me he could only comment on the flight that was in progress, that ATL was a big airport, and treated us, both, in our 80"s like we were children unable to understand the process, and directly in my face in a loud voice, shouted exactly what we were already aware of. Not one ounce of consideration for our problem, of just trying to get home. When he called out the names of the remaining "standby" people, he left several go before us, even though we were there waiting hours earlier. He called out our names, John and Nubia, looked at us and shouted out that he only had ONE, and with a grin on his face, let another standby board, and told that person that she got the "lucky" last seat, still grinning, meaning we had to wait once again for the later flight. This obviously prejudiced and biased poor excuse of human beings needs to find a job he is better suited for, perhaps dog catcher or janitor, IMHO. This entire fiasco put us home more than 7 hours later than previously indicated on our original and paid for flight schedule. If Kayak continues to offer flights with different concourse locations and with only a 44 minute layover, they might also consider a more reasonable and reliable time frame for layover. It was a horrible experience and considering alternatives to this service is paramount.

Flight left on time. In flight entertainment options were good, but needed own device. Crew were polite.

Plane was tooo small, making cracking sound felt lime its breaking down. No tv, wifi doesn’t work. Only 2 restroom

Flight was re-scheduled for the next day. No voucher for a hotel offered. Boarding was delayed by almost 1 hour. No free meal or even water was offered on board. When tried to purchase a coke, was denied because they didn’t accept coins less than 1 euro denominations. A young male flight attendant was especially rude and unhelpful.

Announcement of flight cancellation when we were at the gate for boarding. Yelling that the only thing they would do is hand out taxi or hotel voucher. Group of us were travelling to the same location and we were not accommodated to travel together. I was sent to Montreal with barely enough time to make connecting flight and when I got to La Guardia my luggage was sent to Newark. I got a damaged suitcase next night (after 11 pm).

It had weird outlets to connect to the entertainment. I wasn’t willing to pay for earbuds, so I read captions throughout the movies. The second security check and customs almost made us miss the flight. We thought we would be going through customs in Phoenix.

As previously mentioned in last review , seats are small and uncomfortable, and baggage fees are high!

Never made this leg of the flight since we rebooked through United instead. Did not make it to immigration/US custom due to the delay. Had to spend the night on our own dime in Toronto

We got home a day late because of mechanical problems and that they wouldn’t put us on available other flights.

The 3 hr delay on this connecting flight was a drag.

We were turned away at the gate because our names didn't match (we used a maiden name by accident).

Seats weren't comfortable, could have used more let room

There was no entertainment and no wifi working at all. At least Beer was free and it was a short trip. The staff on board were good

YYZ air Canada security messed up which led to my kids missing their flight and having to go on a separate flight later in the day without the rest of the family. Customer service was horrible and have no sense of urgency or compassion for their customers. They refuse to compensate for their errors and making my kids wait hours in the airport. This isn’t the first time we have had issues with this airline and I won’t be flying with them again.

The flight was canceled. We only found out at the airport. We had to book another flight which cost us more then the whole trip booked through Kayak. Lynx took our email and was supposed to write us with an alternate flight. We never received an email. They talked about reimbursement which was to be explained in the email (which we never received).

The online system for Lynx air to pay for additional baggage is not satisfactory. I was charged 100+$ for my suitcase when I tried to explain that the online payment was not functional using the app and showed screenshots of the same. In the end I gave up and paid and went ahead.

No snacks, just water.... could have been better. The actual flight was good.

Flight delayed by 4 hours but no communication. With passengers until after the posted departure time became apparent the flight was not going to board even close to on time.

Flight was sent canceled. The absolute most useless staff I have ever witnessed. Utterly careless - literally could not care less. 100% never using this airline again.

Poor communication at the check in counter and boarding gates.

Other then the screaming baby the flight was fine, nothing special

Check in experience was smooth, and the flight attendants were courteous and friendly. Very positive experience overall, thank you all!

Flight arrived late but other than that everything else okay

Great price for a new plane. Only offered water which we knew.
