Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I've flown several other airlines, and Delta is really on top on things.

The crew was very nice and very attentive. However, I was surprised to find that they did not carry small throw-up bags. I got sick from the turbulence and they had to bring me a trash bag.😳 You can imagine how embarrassing is to lift a large trash bag with vomit over somebody else's head. Just bring this small discreet little bags back to the regular supply for the seats. Otherwise, I love Delta airlines.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

They were an hour late and they didn’t have my wheelchair for me

Worst food I've ever seen on a plane. One flight attendant must have been going through a bad breakup, although the one who kept covering for her was excellent.

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

due to delay, we were downgraded in seating, so it was cramped

The arrival was pretty bad. Long waits for the bus to deplaning the airplane.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

I do not speak Spanish or read in Spanish When asking for help, people were hard to find they spoke quickly and pointed a lot directions for where to go and what to do we’re unclear. Which made my traveling uneasy.

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke
