I wish I had anticipated the delay at the airport and scheduled my ride pickup for 1.5 hours after the estimated arrival time. I was unaware that passengers from Air Canada flights had to board a shuttle bus to access the aircraft.
Verified travelerFlew with Air CanadaYYZ-DFWApr 2025
Keep an eye on your boarding gate and download the app. Boarding gates will change at the spur of the moment and the app makes things a lot easier and there is nice information on it.
GuyFlew with Air CanadaYYZ-BOSMar 2025
Make sure if you pay for comfort class that you don’t get put in economy.
Verified travelerFlew with Air CanadaYYZ-MSPApr 2025
MSP is one of the most user-friendly airports in North America
Verified travelerFlew with Air CanadaYYZ-IADDec 2024
Get on a regional sized (smaller than Boeing 737 or Airbus A320) jet if you can, they are older and have more legroom than newer aircraft.
Verified travelerFlew with Air CanadaYYZ-DCAJan 2025
Ticketing and boarding was easy, it is a very quick trip, and very good prices
MarciaFlew with Air CanadaYYZ-AUSDec 2024
Have you be at the airport early in order to avoid the rush and chaos.
Verified travelerFlew with Air CanadaYYZ-MSPDec 2024
Get to the airport early to realize a super relaxed experiences
Verified travelerFlew with Air CanadaYYZ-FLLFeb 2025
Bring entertainment, and prepare food before coming to the airport.
LucindaFlew with Air CanadaYYZ-PHLDec 2024
Pay for the ability to have a direct connection to the terminal! Don't tell people that their bags won't fit and need to be checked - but then let them all bring them on anyway!
Verified travelerFlew with Air CanadaYYZ-MIAFeb 2025
Unless you’re single & slim don’t book economy I am not a big person but even so ! I’ve had more comfortable flights to Europe in economy Thant this one!!
Verified travelerFlew with WestJetYYZ-ATLFeb 2025
You need to be proactive for changes. Travellers are already stressed. I did not even get a notification or possibility for a change
Verified travelerFlew with Air CanadaYYZ-BNADec 2024
I would fly Delta Airlines. Never Air Canada again.
BrianFlew with Air CanadaYYZ-ORDOct 2024
Be prepared for a labyrinthine experience traversing the various levels and passages of the Toronto airport. Bring quality walking shoes, as it is likely well over a km in total walking time.
Verified travelerFlew with Air CanadaYYZ-BOSNov 2024
Don't forget about customs at the Toronto airport--it will take 45+ minutes with the lines unless you have a special status program!
Verified travelerFlew with Air CanadaYYZ-IAHOct 2024
Get the United app on your phone. It provides a lot of relevant information about your flight.
Verified travelerFlew with Air CanadaYYZ-LGASep 2024
It is Great to fly air Canada the plane are new,and air bus which I like.
PradeepFlew with Air CanadaYYZ-DFWOct 2024
Boarding in the aircraft should begin from the back rows to the front of the airplane
ChanaFlew with Air CanadaYYZ-JFKNov 2024
Check-in was a little tricky, needed to ask for help. Everything was super on time
EricFlew with DeltaYYZ-SLCOct 2024
Read fine print and ask question before finalizing on payments for upgrades

Less drowsy airport and better service than yyz
Verified travelerFlew with Air CanadaYYZ-PHXOct 2024
I wish we had know about the security check and customs. It was a long distance between gates. It all worked out fine though. I forgot to add that the overhead compartments were built poorly. At least for someone my height and head size.
Verified travelerFlew with Air CanadaYYZ-MIANov 2024
Go direct ! That was fabulous. A/C was good but one flight attendant was kind of miserable. Don't know her name. Michael was good tho/
Verified travelerFlew with United AirlinesYYZ-LAXOct 2024
Make sure you know which terminal to head to upon landing if transferring at Los Angeles as the information board at LAX will show only flight info for the terminal you are at (1 of 8). Transfer information is not transparent from the airline or the airport. Subscribe to airline apps help but can be cumbersome and difficult to manage in a time crunch.
JoanFlew with Porter AirlinesYYZ-SFONov 2024
Maybe get the choice above the cheapest option because you don't get a checked bag or carry on so in the end you end up paying about the same, if not more.
Verified travelerFlew with DeltaYYZ-ATLJul 2024
Delta is great because when you land, you are already on the domestic side of the airport. Since I take the train/subway downtown, way cheaper than a taxi or Uber, I do not have to take a shuttle all the way around the airport to the subway: I just take a quick link train and walk a short distance. Easy and fast! Like travel should be.
Verified travelerFlew with Air CanadaYYZ-LAXAug 2024
It is great to have a nonstop flight. Might be worth paying a bit extra for it.
Verified travelerFlew with Air CanadaYYZ-DENJul 2024
I only wished they had tv monitors. The flight and the crew were excellent!
Jo AnnFlew with Air CanadaYYZ-ORDJun 2024
It seemed that anyone who checked a bag was able to retrieve it quickly.
Verified travelerFlew with Air CanadaYYZ-PDXJun 2024
Avoid Air Canada Rouge. Better to book with Delta.
EdwardFlew with United AirlinesYOW-EWRJun 2024
Have a contingency plan in your back pocket.
Verified travelerFlew with Air CanadaYYZ-DCAJun 2024
The flight is less than two hours, so even though the plane is uncomfortable and crammed full, try to think happy thoughts like, "I'll be off this sardine can soon."
Verified travelerFlew with Air CanadaYYZ-IADAug 2024
Check the departure board carefully when you get to the airport.
Verified travelerFlew with Air CanadaYYZ-PHXJul 2024
After a great experience with Air Canada from Barcelona to Toronto, we were shocked at the low quality of the plane and service on our next flight from Toronto to Phoenix. I have never been on a dirtier, grungier plane.
Verified travelerFlew with Air CanadaYYZ-LAXAug 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.
F.Flew with United AirlinesYYZ-DENAug 2024
Make sure to check the airline delay flights rate and if you have important commitments choose another airline.
AndrewFlew with Porter AirlinesYYZ-SFOJul 2024
I've flown many discount airlines and I think this is the first I will not use again.
JoshuaFlew with Air CanadaYYZ-DENApr 2024
Toronto's customs was one of the faster experiences I've had. They opened four more lanes to expedite the process when the lane got too long, to ensure we would all get through within around 15 minutes. The public transportation within the city is also top notch, in my opinion.
Verified travelerFlew with Air CanadaYYZ-TPAApr 2024
Be at the airport at least three hours in advance and have your meal before boarding. I am short so if a passenger hadn’t helped me, I would not have reached the overhead bin.
Verified travelerFlew with Air CanadaYYZ-LGAMar 2024
Air Canada has helpful staff; the process is easy and no confusion; and Toronto airport is far more organized I have to say in going through security and customs!
Verified travelerFlew with United AirlinesYYZ-IAHMar 2024
Be sure to be aware of what the limits are for taking liquid or cream personal care items.
Verified travelerFlew with Porter AirlinesYTZ-EWRApr 2024
Definitely to fly with Porter, way better than tight spaced and expensive and delays of air canada.
Verified travelerFlew with United AirlinesYYZ-MSPApr 2024
Don’t expect much from the Toronto staff. Maybe they’re poorly trained, maybe they don’t care. The airport itself is badly maintained with insufficient toilets, waiting areas with taped up chairs, and is dirty everywhere. Compared to Dublin and Minneapolis it’s like going to a third world country. Avoid it if at all possible especially if you require assistance due to age or injury.
Verified travelerFlew with United AirlinesYYZ-ORDMar 2024
Carry-on baggage sizing for United US bound flights appears to be much smaller than for Canadian flights, which forced me to check my bag at the last minute. So check online ahead of time
PeterFlew with Air CanadaYYZ-SEAMar 2024
Set your expectations low if flying with AC and then you won’t be disappointed.
AbdallahFlew with Air CanadaYYZ-PHXJan 2024

It’s a short and easy flight. Minimal turbulence and a beautiful view when arriving in DC
Verified travelerFlew with Air CanadaYYZ-ORDFeb 2024
I would definitely choose Air Canada over dirty old United airplanes any day.
MoniqueFlew with Air CanadaYYZ-EWRJan 2024
check which terminal the flight is departing from and landing in!

Do your check in online because it is much more convenient.

The departure time was very convenient with the United.
Verified travelerFlew with Air CanadaYOW-EWRFeb 2024
Just keep pax informed of what’s going on
GaryFlew with Air New ZealandYYZ-LAXDec 2023
Get instructions on how to find your connecting flight terminal and gate in LAX. There are no information boards or information desks. We asked a lady in a gift shop, then it was a series of tunnels and stairs that were not well sign posted at all.
Verified travelerFlew with Air CanadaYYZ-TPAJan 2024
Don’t do it unless you have to. I fly a lot and can only fly mid class & every airline cuts corners in exchange for corporate profits. Flying used to be reasonable in comfort. No more.
