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.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

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. 🙂

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

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

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

I requested a low sodium meal. Reason being, I take medicine for high blood pressure and I wear compression socks on long flights to help with leg swelling. Having less sodium in meals really helps me feel better on long flights. I received my initial low sodium meal after takeoff. Just before landing, the crew came through with the meal cart and offered me what was being served. I said no thank you and then noticed my low sodium meal in the meal cart, with my name and seat assignment on it. I motioned to the crew member, but he grabbed the meal cart and proceeded to move to the rear of the aircraft. He didn’t see me or other passengers who had attempted to get this attention. He was more concerned about completing meal service since we were due to land in under 45 minutes. I pressed the call light five times from my seat to receive help, but no crew member responded to me. So, I didn’t receive a second meal, one that I requested (the low sodium option). This led me to have a migraine from only eating one meal on an 11-hour flight. This is why I’m not a fan of flying US-based airlines overseas. The crew members continue to show the absolute worst customer service experience. I would not recommend flying American for overseas flights.

A little late at the start but all worked out well.

More choices on snacks. Built-in video screen to enjoy entertainment choices.

Wish they had the seat-back video screens for watching movies or playing games.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

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

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

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

Food was ok, but not as good as I have had before on AA.

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.

My luggage was damaged 1 wheel was out I can't find it nowhere

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.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

The service to/from the airport/plane (wheelchair assistance for my mother in law) was exceptional. The staff was super friendly and courteous. The staff on the plane was also very nice. The food quality could have been better (mashed chicken sandwich).
