Subpar. The seating on the plane is almost unbearable. We are literally touching and/or sitting on each other which is totally unacceptable and shameful. Pilots and crew was very accommodating and friendly.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

two hour delay and the Delta representative on the PA system was unable to understand

Very good flight crew and very nice people staff were incredible especially the gate agent

The flight was delayed for about 2 hrs. Other than it, it was good.

My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.

Flying with Air Canada is not pleasant at all. The plane is very old, meaning that there is no on board entertainment, the leg room is less, and it is dirty and in poor repair. To make matters worse, the crew was pleasant enough on my initial fight, but very rude on the return flight. Furthermore, the website advertises many amenities for international flights that are not honored when you were flying from the US to Canada even if your flight is five hours long. Even if you are willing to purchase food, they will likely not have over half of the advertised options available. In addition, you will pay twice the amount of a child’s order for an adult order of same item even though it is the same size as the children’s. It was just really bad on many levels I will try to avoid flying with Air Canada again at all costs

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.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!
