Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

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

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

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.

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Service was professional and quick. Premium economy seat was comfortable given the class

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

Two hours delay, probably one hour because they didn’t bring catering and they had to bring water in board. There a change of aircraft. But delays galore at CLT so it must be a CLT and/or AA operation issue. The 1 hr additional delays because nobody could bring 2 packs of water sooner is probably the best example of this airline operates

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

Another uncoordinated American experience. Always surprises me at DFW for them of all places. Have to take this flight as there are no other good time options. We knew from the start that something was wrong, but the pilot wouldn't tell us. I just watched my Kayak app grow the delay by 10 minutes as it went to 3.5 hours. They were uncoordinated with maintenance (as maintenance, when finally arriving, knew within 15 minutes the plane wasn't going. No 'sorry' or 'this is what is going on' comment. The pilot seemed unfazed / didn't care about the process we were going through.

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

Luggage did not make it onto my plane. Business seats were economy with empty row seat. Just horrible experience. Why would the company allow for transfers that don’t give employees enough time to transfer luggages??

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable
