Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

They were fast and I like how they used to entertainment system to play video about the safety.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

Access to movies was rather confusing. Apart from that, I have no complaints.

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

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.

Experience was good, the wifi hook up is somewhat tough

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.

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

Took 3 hours to check in and drop off our suitcases. Half of the passengers were still in line by boarding time. The computer systems and staff were very slow. Staff were also disorganized and kept allowing later flights to skip lines. Suitcases were piling on that several other passengers didn't get their suitcases. Then, we were sitting in the plane for 2 hours and were told that the flight was overbooked. We missed our connecting flight and had to fly the following day but with a stop over. Good thing ONE WestJet customer rep was pleasant and actually knew how to do her job when we wanted to rebook to a direct flight. Thank you to Kim at Toronto airport. Terrible experience at PUJ. Won't go back to Dominican Republic.

Great seats, super comfortable, but no in flight entertainment which was a let down

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

Flight was delayed due to connecting passengers. Lack of snack options bad. Sitting in Aisle, last cart run pulled the cart directly into my knee. Rude awakening.

We sat on plane at gate delayed without communication as to why we were just sitting there

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

Trash. Sat on the runway for 40 mins…missed connecting flight because of it now I’m stuck. Thanks…a whole fkn lot.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

The plane was comfortable but the crew wasn’t friendly.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.
