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Was revoked with Jet Blue due to delay from Kenya Air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.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

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…

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

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

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

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.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

Really bad experience – delayed for 6 hours without any notice, no food or drinks provided, and stuck in the horrible Cartagena airport.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

delayed due to weather. Could not communicate with family since the wifi was broken
