Airline reviews

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

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.

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

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

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.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

Limited service due to turbulence, N/A Food and Drink. No entertainment

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
