Flight was good, crew was courteous and boarded on time. Cabin space was adequate and the entertainment provided through WestJet’s app is very good.

Plane was comfy and on time

No west jet connect or in seat entertainment. Had to rent. Seems like a money grab

the westjet app is great. however the flight home did not have it..

on our westjet to Puerto Vallarta the air conditioning vent above my brother's seat dripped all over him. on the trip back the screen on the back of the seat in front of my other brother didn't work so we had to share. not terrible, but a little annoying considering the amount we pay for tickets.

One of the crew members was not careful enough while taking something out of the overhead cabinet and dropped something on my head while I was asleep. The crew apologized but it should not have happened in the first place while the aircraft was flying smoothly and there was no turbulence of any kind at that time.

The crew was friendly and funny.

The Westjet staff at the Sudbury airport was not exactly friendly. My flight was departing at 6am, and they ask to be there 45 mins before which would have been at 5:15am, I got there at 5:20am and the gate was closed. At 5:25am an employee came to check me in but still advised me to be 45 mins in advance next time. I was only 5 mins late and they weren't even at the gate on my arrival. The security at the airport was rude.

Good 6.6

On the MSP to ATL leg the gate crew made a huge deal about checking rolling bags. They even stopped us at check-in and nearly begged us to check our bags pointing to the backed up jetway. But we had a lot of unpacking to do before checking our bags so we politely declined three times. On getting to our seats there were at least 8 open slots for bags near us. I heard a crew member call forward to say "tell them no more rollaboards" so they forced everyone left to check. On departure they slammed shut several very large empty overheads. WTF

Flight left 6 hours late with only vague explanations. Simply, "we had to get our equipment in the right places." Attempts to standby on 3 other flights were fruitless and UA airport staff gave no direction or recommendations other than "were sorry."

Left a little early

Smaller seats, no video or music options on a almost four hour flight. Why United why?

Crew was polite

I guess San Francisco ATC (Air Traffic Control) decided the plane couldn’t leave San Fran until way past our take off time. Then it takes two plus hours to get the plane here unload and refuel and rest. So I missed my connecting flight to Redding. Which meant I had to fly to Sacramento. Then I had a pleasant 3 hour drive on I-5 (can you sense my sarcasm?!) didn’t reach my destination until 5 in the FREAKING morning. Around 8 HOURS LATE TO MY DESTINATION

The service as soon as I walked in the first airport until I walked out the last one was excellent for this trip

The crew was very rude, I was told I had to store my purse, the person next to me wouldn't store the carry on baggage, I needed to take scheduled medicine in flight, I couldn't as my purse was stowed. I was delayed for over and hour and a half after arriving. I had to stop and eat in the airport. With chronic health issues addressed this way I will probably not use United again.

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
