Wish we had music during take off and landing like the last flight

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Crew is ok. They offered food n drinks. Had difficulty connecting to wifi on board.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Great. Porter is very efficient, welcoming, and organized. I fly Porter often.

Flight was smooth and comfortable. The crew were exceptional. Amanda, Nichole and Hershel were attentive to our every need. So friendly. My daughter and I were surprised at quality of service. Loved the double row seating. Snacks were delicious. We would definitely fly with Porter again. Flight PD 670 SFO to YYZ Thank you so much for the best flight experience we have had

The E195-E2 is a great aircraft! Leather seats, lots of legroom and SO quiet! The flight crew is terrific!

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

Flight delayed 6 hr. Looking for compensation and will claim for it.allow US people to fix to avoid huge delay having a canadian tech to fix it.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

Energetic crew - flight full of swiftied going to Taylor's opening show in Paris! Long lines for bathroom made out kind of suck though

I’ve had a couple flights this week on United that were delayed by an hour or more

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Nothing beats ANA customer service on my opinion. Maybe because of their Japanese culture (and food). Arigatō

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

It was spectacular. I had basic Economy and was given so much space and their seats lean back so far. Staff was superb, food was superb, everything was superb, Finnair is Fantastic.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

My flight got canceled. Then AC rebooked me to a next day flight. No compensation no apology. It almost messed up my entire trip and schedule. However, all the unexpepected seems routine and ordinary to AC, so customers need to get used to.

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

For such a long flight they should offer tea or coffee in between two meals.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.
