I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Flight was delayed for about an hour but overall good experience

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

Abysmal overall. Delayed flight caused me to get in with an only 9 minute connection. No help from flight attendants or gate agents to try to make the connection. Second flight left 5 minutes early despite not having at least 10 people on it, including me. Rebooked 24 hours later. I asked four separate delta agents how to ensure my bag would get on the rebooked flight and all assured me it would be there. Landing in Rio right now, 24 hours late, and just got an alert that my bag didn’t make it. Horrible overall experience.

4 hour delay. So our flight schedule mass up. Your worker told me you should rebooking myself. I was very angry. Latam Airline always get the money more through any way. But They have no concern passenger.

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

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.

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

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.

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.

Never nice, United Express partners always do an amazing job.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The flight was on time and the crew were great.

I was forced to gate check my carry on luggage. Somehow it did not arrive at my destination. I still have yet to receive my bag r days after arrival.

Boarding area is a mess. Lines not bounded and gate area too small. Food options (on this specific flight) were poor and you couldn’t pick part of it since it was like a mash of chicken and other unrecognisable stuff. Comfort of seats along with child noise made it difficult to get a good sleep. Last, the flight attendant that served my aisle was rude (others seemed fine) towards me and others.

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight was on time and smooth. Customer service was decent

They forced me to check my hand luggage at the gate.

Still hasn’t left. Why are you asking how it was?

My flight got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.

Flight was delayed which isn’t the airline’s fault, but the communication around it was terrible. I left the lounge to show up at the gate to board at the time in my app, and the flight in front of mine was still boarding and the inbound plane hadn’t even taken off yet. Delays were slow to show up in my app. Improved communication could have let me have a more pleasant experience in the lounge vs waiting 1.5 hours at the gate.

Wifi was good on the flight from DCA to Dallas and terrible on the flight from Dallas to Tucson. The forward head in the flight from Dallas to Tucson was putrid smelling entirely urine soaked. The flight from DCA to Dallas was delayed by almost 30 min with a plane change.

Sat on tarmac at arrival at DFw for more than 30 min waiting for a gate.

Business Class layout was excellent. The seats were not nearly as comfortable as UA, Delta or Air New Zealand (the best). Nor were the controls as flexible. Food was okay but not great. Breakfast pancakes were like cardboard.

I am Plstinum Pro snd was standby on earlier flight. They gave seats to people that asked rather than follow standby order. When realized what was happening was too late to get on as no seats left. My scheduled flight was late. Then filled the seat beside me Ruth rude person that they had to move from her original seat

I have yet to come across an AA agent or flight attendant that is friendly. They really inhibit a good experience.

Flight was good, little delayed because of busy plane traffic

Flight was delayed multiple times and rerouted to different concourses in the airport because of all of American's delays. App/boarding pass would not update with changed gate information.

Did not know that they didn’t have screens for entertainment. I didn’t have headphones so I couldn’t watch anything on my phone.

Disorganized boarding. Mandatory to gate check bags. Curt flight staff. No space for cabin bag, even when I was in first class.
