The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Okay considering we had weather delays which the Pilot notified us of immediately!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

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

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

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.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

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

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.

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

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

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline
