I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Full flight where I had another passenger sitting in middle seat who said that he had lost 250 lbs from 500. The stewardess on exiting the flight advise me that I was going to receive a refund. I thought she was talking about another passenger. The stewardess saw that to make him comfortable I had lifted the armrest and flew for 5 hours to Seattle from Reagan DCA with a portion of his body on my seat. I survived. I flight to remember!!!!

the flight was delayed almost 3 hours and not one time was we told that it was delayed or why. I had asked one of the crew members why it was delayed, 20 minutes after the flight was supposed to take off, and was told that they had no idea what was going on and that they had not been told anything. this is FRIGHTENING!!!! No excuse!!

Flights were on time. Check in was fine. Crew members were pleasant.

I would have liked it to have been easier to order food for the flight. My son was not happy with the snack pack I bought him and it was a very long flight for a little boy to go without food.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

I got to my destination but no comforts no snacks nothing. Like herding cows!!

My only comment was the confusion at Houston. Suppose to leave at 6 am and didn't leave til 11 am. Then moving from gate 10 to 30 and couple of hours later back to gate 10. Otherwise everyone everything was great.

The food options could be better. Possibly some sandwiches to be added to the menu.

The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day. Her inch long fingernails said it all....I really don't belong here. Other than that, WestJet personnel provided a good travel experience, especially in flight. I must say that the repeated announcements about the cabin being full and how folks should gate check their bags became tedious. WestJet should just offer free checked luggage and charge for carry on suitcases. It would save a lot of time and the voices of the gate agents.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Departure delay on a late night flight. Made us even later. Tired but got home.

Westjet forced me to put my carry-on baggage in check-in probably because I was assigned seat 23A (the last row seat), which had no cabin space, which is unfair. I wanted to carry on my luggage so that I don't have to wait at the airport for my luggage. Also, because there was no cabin space, I was forced to keep my laptop bag under the seat, which I didn't want to as I was carrying 2 laptops and charger. The airline should basically tell people that if you are assigned a last row seat, then you are not allowed a cabin baggage or a personal item.

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

We were redirected to a near by city due to weather and had to stay in the aircraft before flying to the original destination's airport. The whole delay added 3+ hours and were were not offered any snacks or water.

Air Canada had a lot of delays on our flight going back to Seattle. So much inconvenience for a long trip.

The Carry-on luggage that approved by TSA and all other airlines,- always an issue with Air Canada. This is inappropriate as my carry on suitcase meets the requirements however it always asked to check in on AC flight on the gate. Yes I have it for free, but it takes extra time to pick up on the carousel. Apparently it fit the overhead space, so why AC has this issue all the time?

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.

Seriously need to improve the time schedule and the plans

Great TV, easy boarding, wonderful ground crew and flight crew.

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike
