It was a pleasant surprise to have complimentary Wi-Fi on the flight

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Apart of Sky miles delta. And they go everywhere in Brazil

Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

The flight was late. Please do not delay next time.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

No screens or meal options. Freezing cold. Dirty seats. Left late.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

We had several flights and they were all on-time and flawless

My Frequent Flyer nber wasn't put on as I was told it was..... This resulted in a last group boarding and no priority tags on My bags.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

Flight was delayed an no one cares, or try to help passengers to get the conexión.

Our flight was cancelled while we are on our way to the airport. So, no notice. We were rescheduled to another airline with a 2 hour later takeoff and so arrived at our destination on time. We pre-paid American Airlines $190 to upgrade our seats. No refund. So no use for AA or Kayak.

The small flights with Valet Luggage has a poor service

Terrible, horrible, disappointing- without telling us they changed planes and moved and separated our seats to opposite sides - said they changed seats putting us together - got to airport to find no, they did not - we sat opposing sides of plane - food overly salty to inedible, never saw stewardess but once - it was terrible

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.
