In some Delta flights that I had in the past the plane was just ok, not bad, not good. But this plane ATL-MEX was great, very nice and conformable plane, it looks and feels excellent!

After flight was cancelled, rebooking was easy and quick on the app.

Flight was cancelled. flight attendants were grumpy. One of the tightest seats I've flown in economy. No room in overheads so I had to stuff my winter coat between my legs with my backpack under the seat in front of me. Was basically wedged into the seat with my stuff.

Quick boarding, clean plane, good entertainment system.

Used a neck/back pillow and jacket against hull to try and keep my shoulder and arm from freezing solid. I usually sit by the window on a couple dozen flights per year, and it has never been this cold on my arm. I wonder if a heating pad would work on their outlet?

The check in process was very easy. The boarding process was very easy. The flight attendants were very pleasant.

There was not anything to complain about.

Prompt service and proximity of airport to the city. We literally walked to our hotel

Arriving and calling someone to help me with the wheelchair was good. The women were so friendly and helpful. But when you're "stuck" in a chair and I arrived early, it would be nice for someone to check to see if you had to go the washroom. And I had to flag someone down to get me to the aircraft. No one came by and offered. But overall fantastic experience. I would fly porter again.

Wish their was more food on the flight. Even though it was a short one.

comfort

On the first leg Flight 720: 1. A Black man sitting behind me was challenged (and humiliated) by a Porter agent who came on the plane before leaving the gate, that he was sitting in the wrong seat. It turns out the agent was looking at his boarding pass for the NEXT next connection flight. That delayed the take off by 10 minutes. 2. Then while taxing away from the gate for takeoff, another Black man on the same flight whose mother tongue is not English nor French, did not understand that he had to remove his earbuds for the takeoff. He said he was confused by the instructions, so the the pilot decided he was "non-compliant" and returned the plane to the gate to have him removed from the flight, bring police on the plane. I am sure he lost a lot of money and will have future difficulty flying in North America. That delayed our flight another 40 minutes, and many of us missed our connecting flights in Toronto. I just have two wonder if a white passenger would have been given the benefit of the doubt.

The waiting lounge was nice and complemented with refreshments

When I got to Toronto I was directed to the wrong lounge for a while before I asked and was redirected to the correct lounge

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
