Delta continues to decline. This was international flight with paid meals & minimal knacks. All drinks were served in paper coffee cups including wine & bee that was purchased, The bathrooms were not cleaned & maintained. Trash container was overfilled with no placed to dispose paper towels. The flight arrived safely. That counts.

The flight was over 2 hours late.. once we finally got boarded things were fine

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

Flight was delayed for about an hour but overall good experience

Flight team was great and we even arrived ahead of plan!

The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.

Boarding was quick and i made my connection early due to early arrival time

No food or drink, Not much conversation with crew. They didn't come through to check on people. There were no charging stations or wifi to watch movies. It was like being on a bus in the air.

Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

Excellent. No issue and it was on time and arrived early, the best!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Lost luggage, they need a baggage service representative available all times in Atlanta

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

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

The staff was so kind and very helpful. I had to use handicap wheelchair services and was so thankful for how well they treated me during my whole trip. Thank you so much. Jessie took time to explain his service and what part he played and how others was going to be available to help. The flight attendants was so helpful in helping me get to my seat. Made me want to plan my next trip with United Airlines. I usually use Delta.

WiFi never works on any flight and the attendants can never get it to work. You would think paying so much for business/first would give WiFi. Also, the food in business is really poor these days.

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.

Price was good. Entertainment and food could have been better

They kept making changes to the itinerary. I actually wasn't able to go and i tried to get flight credit in exchange for the ticket, but the customer service chat was taking way too much time.

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

it's all good nothing you can do make better 😌

The seats were some of the most uncomfortable I've ever been on. Other similar-sized jets with the same seating arangement have been far more comfortable. This interfered with sleeping, so it was a big issue. Moreover, the lack of a digital boarding pass forced an extra trip to print one, and the overall digital experience was poor. WestJet's website could not figure out one of my flights existed.

Still sitting in a hotel when I'm due for work

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Digital check in is very poor with air canada compaired to other airlines

Took off on-time and staff was very nice. Got stuck on tarmac at ATL due to storms, but staff was still wonderful even though they were working and not getting paid.

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.

Unfortunately my flight experience was poor as my flight was delayed with multiple gate changes. I did not reach my destination until almost midnight. I'm hesitant to fly Air Canada in the future.

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

It was almost on time. But the TV did not work. The washroom was too small and it was a mess. It was a toilet paper explosion.

Your survey could have a not applicable because there was no food unless you bought it and I didn't.

Canada's airport is disorganized, He have to start recruiting so that the line at immigration moves quickly.
