Was great, under the wire!

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.

2.0 Poor
Everything could and should be better. We are paying for, it's not a favor, it's a service and should involve quality, responsibility and respect.

2.0 Poor
Communication doesn't exist. If you have any issues nobody will help you. I was told that the supervisor doesn't want to talk to us no matter what we need, so if you have a problem that's your problem. And the website doesn't work also, even to pay in advance for the first baggage fee. People with handicap needs of assistance are in a very bad situation also, because one single person has to handle two or three wheelchair at the same time, running and living you alone literally at the airplanes door waiting when even the pilots and crew members are already living and about to close the gate and you are there waiting for someone to show up to take you in a wheelchair to where you need to go, and some employees are nice and still trying to help you, but is hard to them to hand to much, and others are just very rude, and even told us that they are looking for better jobs. The food wasn't enough for all the passengers and the ones like us on the back of the aircraft had no choice but accept what of left doesn't what it was because the people of the front took most the food. The delays were everywhere and people walking gate to gate to find where they should go for checking, but nobody knew anything because they changed everything on last minute. You, the passengers, have nothing you could do about nothing, even when you told them that the rules and regulations says that if that is a delay more than 3 hours they should pay you for that, but what they gave us was only 12 dollars for me and 12 dollars for my daughter, two handicap people after all these troubles, and after we had the need to beg for water and food. Everything in our trip was just terrible 😕 😪 😩 from the beginning to the end when the people that suppose to assist us with the wheelchairs left us in a isolated spot where we should wait for Uber to pick us up, in the meadow of the night due to the flight delay (departure was 7:55 PM, MCO to Logan, and was delayed until 12:45 AM, when we were already waiting for our connection for more the 3 hours from the previous flight from GRU/Brazil with Latam, the worse carrier ever). But we did accept the voucher for food and again they left us at the court food at the airport and we had to call them to go there and pick us up otherwise they would not even notice that we would being left behind. I don't really appreciate anything 😕 and I felt disrespected disappointed and very frustrated because nothing worked even before on the website, the phone calls, and the rest I already told you.

Seats were comfortable, 8 hours. One flight attendant was not appropriate in his verbal response: "Please, DON'T touch me.", after being tapped near his elbow after being made unaware he skipped serving me & had passed further down the aisle.

6.0 Okay
Boarding in Amsterdam is always chaotic. More complicated than needs to be ( boarding pass checked twice, once for general security, then by the airline). The bathrooms on this flight are dirty, and smelly. The food was mediocre at best The crew was decent

8.0 Very good
Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.
S
6.0 Okay
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.
B
8.0 Very good
Round trip flight to Canada and back to the US was smooth and efficient.
