The Turkish was good . I had a problem with air Transat terrible experience for me

I did not like I have been charged for my carry on

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Very good. A lot better experience then I expected for an economy flight.

It was very good but no tv but the experience was great

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Nice complete meal included and great services. Plus the plane was very clean.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

l really enjoy very much the flight was very pleasant

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

We didn't take off until an hour after we boarded.

The actual trip was fine, however, the changes made to our flights and the layovers were had to endure were awful.

The flight was on time and crew were nice, seats were tight and there was entertainment available

Good service, friendly staff. Food was average for airlines and the seats were small.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

No food offered, just chips. Crew was no nice. I had to Stand up and ask for a drink. Even for a midnight flight I have had better experiences from another airlines.

Flight left on time. The crew was very friendly. I had to buy a proper meal. Small cookie and a drink just doesn’t cut it for a 4.5 hours flight.

The flight was full and good as could be expected. We arrived early which is always a good thing.

Experience was good, the wifi hook up is somewhat tough

Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

The delays were never ending and we were never properly informed as to why. 1st and 2nd delay were handled well, but by the time we received our 7th delay, and then subsequently asked to willingly get bumped, it turned into one of the worst flying situations of my life. I didn’t get home until 2am which is roughly 5 hours later than originally planned.

Great flight, great landing, nice staff. Our seats were a little cramped.

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

No food, water, snacks.”beverages”. This was on Christmas Day. Upgrading cost $100, for what exactly?

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Very short flight. No food or entertainment required. Nice crew. Flight left late.

Overall a good experience as this leg I was in Business Class. The Lounge was amazing with a view of the planes. The flight attendant spoke way to quickly when giving the information for take off and landing and it would be of no use to a first time traveler. Overall a great airline to travel on.

Smooth on-time flight but NO AC in the middle of the cabin. Business Class and the rear of the cabin were too cold but mid-cabin was stuffy and hot with virtually no air coming out of the ducts. Made for a very long and uncomfortable flight.

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

The airplane has been replaced and late night layover have been extended from 3 to 7 and the only compensation was a $15 food voucher after most restaurants have been closed, not helping with children after a 18+ hour international flight

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

This flight with a lot empty place , and I have more room, feeling comfortable.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

I accidentally touched a cabin steward as she passed by and she reacted harshly yelling in a loud voice “don’t touch me”. It was embarrassing and uncalled for. I would characterize a few of the cabin crew as pretentious and aloof. Not at all what is expected. That was the first leg of our trip from Montreal to Munich. The second leg from Munich to Nice was more in keeping with the service I expected.
