Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

Flight was delayed over 2 hours, then landed at a different airport!

The whole experience from check in to deboarding was fantastic.

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

Great! Personable crew. I love that they pour complimentary beer and wine.

I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

The plane was pretty full, and we dis not have any includes meal for our 4h30 flight? And on-board entertainment wasn't available, there was no TV or plugging to charger your device on the plane. They told us to download an app if we wanted to watch movies but it never connected, that was a disappointment, the r we st was very good though and the crew were really nice!

Seats were very tight especially for first leg of trip.

Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

The flight was excellent, once it started, however we were delayed two hours when the first plane’s engines wouldn’t start. They found another identical plane and transferred us and our luggage in under two hours and made up almost an hour in the air.

Really low cost trip for the huge amount I paid…o paid 550 dollars just for the trip, one way trip, plus 95 for 1 luggage’s and the second 135 dollars…no blanket, not headphones for entertainment, food was served after 3 hours and 2 hours after, breakfast was served Bad, low cost company for high prices

The food should improve! And The flight should leave on time and not make the traveler wait.

We love united ! We would like to acknowledge Aimee in the lounge near gate 130

Survey sent before we actually left. Delay after delay. Now a crew problem.

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.

They changed my seats after I checked in and I was stressed from the time I saw that information until just before boarding, when the gate attendant fixed it, but it shouldn't have happened. And if it couldn't be prevented, then the people on the phone I spoke with should have done something to help, which they did not, nor did they offer me compensation, just meaningless apologies.

The flight was operated by Lufthansa. You can't expect much from them anymore. They have a talent in getting something wrong.

Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.

Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.

Not really their fault, but a 4.5 hour delay is pretty brutal

Everything was good till we got to yyz...then we got to the gate and there was NO GATE AGENT. We waited 15 min before disembarking. No internet No IFE Old aircraft Second leg in two weeks NOT IMPRESSED

The seats are soooooooo small in economy. I was offered no tea or coffee in the am. When I asked was told that it was too late. The plane was 2 hours late leaving.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Flight was delayed 1.5 hours as crew was stuck in traffic...that is absurd that the airline would be transfering a crew by car through NYC during rush hour. I missed my shuttle bus and got stuck in Vancouver for the night. Airline did not offer a voucher

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

Terrible - flight was flagged for fraudulent payment from being booked via Kayak. Requested to rebook with original credit card or provide new payment. Air Canada stay at JFK did not know how to process new payment. Had to fly from La Guardia 2 1/2 hours later instead with Air Canada.

Very poor.!!! They cancelled our flight and rebooked us with very little time to catch the flight. Our luggage was lost. As of now we do not have it yet. No clothes to change on the second day of vacation.

Even after booking in advance and getting to airport early, multiple delays and gate changes as well as forceful check in of bags even though it is within size and weight limits.
