Planes were clean, no water or snacks on either flight.

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

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

There was a mechanical issue with the plane that they had to work on before we could take off. That's fine, by all means, PLEASE make sure the mechanics are functioning properly. What was a problem was the fact that we sat on the tarmac for 4.5 hours without moving, without letting us off the plane, and without climate control and air running through the plane. There was no explanation as to what was going on; they just kept promising that it would be "15 minutes, then we are on our way." At one point, they even switched the entire crew out and told everyone we just needed to wait for new employees to show up. Then, as the 4 hours were not moving, an hour before the full refund, they made a big show about "the flight starting and the doors are locked, so you have to sit down." We didn't move for another 40 minutes; they were just trying to skirt around legalities that entitled us to restitution. When the flight finally was underway, the plane was gigantic but cramped in design, my entertainment screen kept freezing and glitching, and subtitles didn't work, and the crew was passive-aggressive. Terrible flight.

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

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.

Poor, the airline was not able to help me move flights.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Lost of requested seat assignments. Lost my husband's meal choice

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

Was given all 3 boarding passes. Was refused boarding to Brasilia in Miami even though I had up to date Brazilian Visa and US passport. Had to return to Phoenix as trip was cancelled. Waiting for refund of the fare. Missed my son's birthday and visit with him and his wife.

The pilots landing and taking off was very bad on the first flight, the second one taking off was great but landing was also rough

The check in and on the ground experience is very poor. Their online check and trip management is the worst I have ever seen and they have long lines to check in at the airport, technology is glitchy/unusable and have exorbitant baggage fees. The flight itself is fine, although the food is about what you would expect and their was no functioning entertainment for an international flight.

My experience with this flight was extremely negative and resulted in serious financial and personal consequences. The flight departed with a significant delay, which caused me to miss my international connecting flight. As a direct result of this delay — which was entirely beyond my control — I was unable to reach my final destination on time, causing me to lose a previously scheduled hair transplant surgery that had been arranged months in advance. This was not a minor inconvenience. The surgery involved: • A reserved operating room • Medical and technical staff scheduled specifically for that date • Surgical instruments prepared in advance • Strict scheduling that does not allow for easy rescheduling Due to the airline’s delay and poor handling of the situation: • I lost already paid international flight tickets • I was forced to purchase new tickets, incurring duplicate expenses • I spent over six additional hours in airports, under stressful conditions • I incurred unexpected costs for meals and transportation • I lost a medical opportunity that cannot be easily recovered, along with the emotional distress associated with it Although the airline covered one night of hotel accommodation, this did not address the real impact of the delay, nor the significant damages caused by missing a critical medical procedure. The lack of punctuality, planning, and effective solutions reflects a serious lack of responsibility toward passengers, especially when international connections and time-sensitive medical commitments are involved. I do not recommend this airline for travelers with important schedules, medical appointments, or critical connections. In my case, the delay did not merely cause inconvenience — it resulted in the loss of a surgery and substantial financial damage.

I was not able to get on the flight due to delays out of Philadelphia. I arrived in MIA at 10:30pm and there was no one at the GOL Desk. Is there any flight credit available for this flight?

I have a hand injury and the flight attendant denied to help me with luggage, she said "she couldn't help me because I should manage my own way to put the luggage on the plane" SO RUDE

I had two around 6 hours flight and they did not even offer water to us.

Overall it was good. The food was not great quality and seats were very uncomfortable. But overall the staff was very friendly and helpful.

We flew with Avianca, some how they are not n sync, making the process a bit uncomfortable.

Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

They lost my baggage and I am still struggling to the information and update

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

There were flight delays making our flight arrive at our destination after midnight didn’t seem to have enough crew or airplanes for the flights laid over in Dallas should’ve had plenty of time to make it to our next flight only made it because that flight was also delayed because our plane wasn’t even at the airport yet overall have not had a good experience on American

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

It's a long flight and that is always difficult. I was comfortable and well. The movies available were great and the crew was good.
