The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

Delta changed our flight a few months prior to our trip and we couldn’t get as good of seats on the new flight. Because of that we couldn’t sit together which was very disappointing. On the flight after a few hrs the bathrooms were filthy. The seats were comfortable - we were in comfort plus. The food was not good. The dinner was average but the morning snack was uneatable with horrible coffee. We have always preferred Delta comfort plus for our overseas travel and usually the food is decent, but not this trip.

They boarded very early. We rushed to transfer and got to the gate 5 minutes after boarding was scheduled to start, however they were making a last call and holding signs for “all customers” to board. They were helpful at the gate, but I was surprised to see that we were some of the last to board at 5 minutes after scheduled boarding was to begin.

Good flights. On time. They had a gluten free snack option which was nice

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

The WiFi didn't seem as fast as it normally is

Friendly and helpful crew. Had no issues at all other than the St Thomas airport is woefully small, so allow plenty of time. Flight was pretty smooth and we arrived earlier than planned.

Friendly crew, quick boarding. We even arrived a few minutes earlier than our original flight plan. No onboard screens, but it’s a relatively short flight so it’s not really an issue.

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

The seats are totally uncomfortable making the flight less than pleasant. The cookies & pretzels were terrible!!!

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

Terrible. First my return flight was rescheduled to a terrible itinerary. Paid for window seats where there was no window. All of my seats were mediocre or terrible despite paying in advance for them. Zero onboard entertainment- it didn’t work or wasn’t available. If it was available there were zero instructions provided. I also didn’t like being forced to check my carry-on luggage. Delta screwed me around on the way home with a 2 hour flight delay that caused me to miss my connecting flight so my luggage did not come home with me but had to be shipped on a later flight. Just grateful they found it. But Delta attendants lied about the delay - a supervisor at an info booth assured me they would compensate because it was the fault of the pilot arriving over an hour late but when I went to the boarding gate to get help with this they insisted it was a ground problem in Toronto and not Delta’s fault BUT another flight to Toronto was going around the same time with no delays and West Jet agents in Toronto said there was no notice of any ground delays at the airport (which I have on video). When I went back to the info desk to find the Delta supervisor she was gone. I had to run through Toronto airport asking any availabile West Jet staff I could find to book a new flight home as I didn’t have a connecting flight anymore. Baggage wouldn’t help OR give me my bag back. Because we were one of the last flights into the airport all staff had left. I finally decided to go through security to find an agent at a boarding desk and was lucky to catch one before she left to get booked onto the next flight home in the morning but I still had to spend the night in the airport. It was awful!!! I was scared, travelling alone and desperate to find help - which was a extreme challenge. Maybe 2 out of the dozen people I asked were pleasant. The rest difficult. I felt betrayed. Oh and I kept getting directed to the information desk in Toronto airport but no one was on staff and I used the phone to try calling someone but I kept getting useless recording. I will not be flying Delta or West Jet again. It will be a long time before I feel safe to travel again. Many tears. This was an awful and highly stressful experience.

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Lots of delays and a broken plane, would not recommend

Westjet is the worst airline. If you fly with them, you can expect 100% delays or flight cancellations. I support all Canadian, but not Westjet. They are terrible at what they do and will avoid them as much as possible.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Very smooth flight and the crew members were very welcoming.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

ground crew at Casablanca as well as at Montreal was not helpful at all. specially at Montreal airport, very rude .

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.
