Pros: "It’s nice that a snack was provided. Other airlines have stopped serving snacks because of COVID-19"
Cons: "Crew could have been more welcoming."
Cons: "I paid extra to sit in the front of the plane and the flight attendant kept an egregiously bright LED light on that shined in my face the entire 4+ hour trip. I was really tired and extremely upset that there was no curtain or anything to stop this light from shining directly at my seat."
Cons: "Three gate changes and then delays of ramp connecting to plane. It was ok"
Cons: "Left 5 hours late. Not notified til I left for airport. Sat on the plane almost 90 minutes before we took off. Flight was good"
Cons: "The flight was delayed for quite awhile. I had been traveling all day and I just wanted to go home. We also were not informed why it was delayed for so long."
Cons: "Tv’s were fickle and my other seat had no audio."
Pros: "The flight was on time, and we boarded quickly and promptly."
Cons: "They sat me next to the bathroom which I found really disgusting. It was hard to eat while listening to people endlessly flush the toilet. Disgusting."
Pros: "The crew was very helpful as always ."
Cons: "Deplaning could have been faster but I have no suggestions how to fix this."
Pros: "Crew was great."
Cons: "Everything was fine. It was a smooth trip to Denver."
Pros: "The crew was great. They let me go back to see if I could find my laptop that JFK TSA did not return."
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Pros: "Love the fact that the head rests move to support your head better."
Cons: "No meal option and my video screen volume did not work"
Pros: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Pros: "Crew was amazing."
Cons: "Delayed departure due to late crew arrival. Not a huge deal."
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
Cons: "Seat assignments. My husband and I were not assigned seats together, however we were able to sit together because the seat next to me was empty."
Cons: "Service is awful, they cancelled a flight and they reserved the wrong flight so we couldn't get to the destination. Had to change airline and extend our flight by 9 hours with our baby. Horrrrrrible experience. Staff didn't seem to care. They put everything on their supervisor and she tried to help"
Cons: "After landing, we were waiting on the tarmac for sometime and I needed to use the restroom I was an allowed to do so. It would’ve taken me a short short time. I went to The rear of the plane to use the restroom and was told to get in my seat."
Pros: "Friendly staff And I love it you go direct to Belize."
Pros: "I liked the price for my flight however I booked using my AirMiles."
Cons: "I have travel with WestJet many times is the past and had nothing but good to say. This was my first time using WestJet Encore and was totally shocked and disappointed. The flight crew i found to be very rude with and had an attitude. The biggest shock was the greetings and all announcements were in English accept the safety rules where the pre-recorded tape was played. If asked about the return flight from Halifax to Montreal, one word to describe it "disaster". I was totally turned off with WestJet. I will for sure continue using Porter as I was always pleased with there service. As they say "you get what you pay for"."
Pros: "Westjet team is fast, nice and solve issues in one call. I have had very good experiences with westjet! Thank you!"
Cons: "Today in Montreal during boarding the lady coordinating did not give priority to people with children. We were at leastthree families - we were all upset with the situation. However as I have had very good experiences with west jet I consider this an isolated issue."
Pros: "We were late getting to YUL because of traffic, and a West Jet employee went above and beyond to make sure we made it on our flight even though we missed the cut-off time."
Cons: "No entertainment on the return flights Yeg/Yul !! Makes for a long flight."
Cons: "They tried for force us to pay for a different ticket because we had gotten a cheap initial ticket!"
Pros: "I love flying in a smaller plane. They are usually not full in the morning and so it gave me a lot of space to relax and enjoy the flight from montreal to toronto. The crew was really nice and smilling and they made sure that my pet and I had everything we needed."
Cons: "The seats are pretty thin and uncomfortable. There is no wifi or television on board."
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Pros: "Good entertainment choices."
Cons: "Uncomfortable seat with insufficient legroom wouldn't recline. Inadequate overhead storage (full flight)"
Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."
Pros: "No major screw-ups this time!"
Cons: "It's AA, let's not try too hard here."
Cons: "American Airlies no longer partners with T-Mobile for free WiFi. :-("
Pros: "Jesus, the flight was phenomenal! He lightened up the atmosphere with his wit and grace."
Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."
Pros: "Good boarding and on time departure."
Cons: "Very uncomfortable seats and spacement between the seats too small and you feel very cramped specially when the person in front of you reclines his seat you can hardly move."
Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"
Cons: "Didn't like the two hour delay, especially when I was notified only a half hour before boarding! This seems to be a normal thing for American Airlines."

Easy getting to boarding waited a hour in the plane before takeoff, made us miss our next connection

Flight was canceled and we were switched to a time I did not like. Then we were switched to a different airline. Then the flight was a little delayed.

Pros: "The crew that greeted us (and sorted out seats) was excellent."
Cons: "We had booked seats together two months before our trip; when we checked in (both legs are Star Alliance, but Air Canada—one leg both directions—did not allow any on-line seat choice or changes), we had been separated to different rows altogether (and since it took two Air Canada trips to get from Vancouver to Denver; the first had mechanical difficulties an hour into the trip and had to return), and there was no way to change it online or at the airport."
Cons: "Air Canada changed our seating on day of travel. I had ordered tickets over a month in advance and scheduled seating for my wife and I on our 3 leg flight. Air Canada changed our seating on the 1st and 3rd leg and we were no longer sitting together."
Pros: "new airplane, some juice offered, good entertainment, staff was ok on the return flight (first class)"
Cons: "nothing to eat, no leg room, poor wifi, hidden fees for checked luggage, damaged baggage on the return flight. I asked for some more water on the first flight, and the guy gave me a look as if I had asked him about his soul."
Pros: "The crew was very attentive"
Cons: "As much as the flight was truly very good and the crew very friendly and helpful as much as the equipment (airplane, seats, entertainment) really shabby and certainly not worth the the 2500,00 $ I paid for a better seat. I could of flown with Air transat and get better than I got with Air Canada. I feel it was rip off. Quality - price not there . Please give your crew a better uniform. The ones they wear now is very sad and oldish looking. If I think this and am 67 years old, imagine what the younger generation thinks."
Pros: "Nothing"
Cons: "2 hour delay because of rain west jet and porter were on time but air canada delayed My seat was apparently broken had a window seat with no one else in my row and then I was placed ina Center seat although other options were open The attendant comes on the air and says they need to manually start the engine one by one because the electric start to make it easy was not working All and all not a pleasant experience at all"
Pros: "Everything was perfect on the flight. The service, the food and the crew."
Cons: "Seats are a bit small. Not very comfortable and touch screen of entertainment system was slow."
Cons: "boarded and closed gates 30 min early without warning. almost missed it"
Cons: "Never been on a smaller plane. I've traveled private planes with more room!! Air was so bad, even the food smelled bad and couldn't even think of purchasing any. With a flight that long and people waiting for stand-by, you'd think a larger plane might be in order."
