We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

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.

Due to a delay in boarding in the previous (Copa Airelines) flight, I barely made it to the gate on time. To make things worse, the seats were very uncomfortable, there was no screen for entertainment (on a 7 hour flight), no charger (but a USB port), and there were no options for the meal, just a single offering (which wasn't good either); no breakfast or snack was offered either (this was an overnight to early morning flight). Would not recommend.

It is not a good experience with Copa Airlines: flight delay, luggage delay, etc.

We where skipped for this flight will not head to Panama until tonight..

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

Very happy with my flight. I would definitely recommend it.

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

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.

Tiny seat made for midgets. You can’t put a normal size human in such a tiny seat for 8 god damn hours! Hot plane, no air. Lost bags at Rome airport for 8 hours, lucky to have found them. Horrible flying experience, United Airlines should be embarrassed!

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

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

Short. Nice quick flight, appreciated after Munich to DC leg.

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

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

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

I have generally had positive experiences with American Airlines (outside a handful of delayed flights), which is why I wanted to share this feedback constructively. On my recent flight, my travel experience was extremely uncomfortable because my seat mate significantly encroached into my assigned seat space for the duration of the flight. As a result, I was forced to sit partially sideways, with much of my shoulder and upper body extending into the aisle. Unfortunately, my back still hurts from maintaining that awkward position.I recognize that this is a sensitive and challenging issue for airlines and cabin crews to address. Everyone deserves to travel with dignity and respect, and I understand that individual circumstances can vary. However, fairness also requires that all passengers have reasonable access to the seat space they have paid for. When one passenger's use of space substantially impacts another passenger's ability to sit safely and comfortably, there should be a practical solution available.I appreciate the complexities involved, but I hope American Airlines will continue exploring ways to ensure that all passengers can travel comfortably and equitably. This experience detracted significantly from what should have been a routine flight.

Crew tried to accommodate late arrival due to late departure

I injured myself during my trip. The staff of American Airlines were very compassionate and empathic. They took additional steps to make my experience easier. Thank you!!

There was no ground crew at HSV gate when we arrived. The were busy with another arrival. We had to wait 20 mins for them to arrive and direct the plane to the gate. It took almost 45 mins to get my luggage. The luggage belt had 3 flights bags on it and the other 2 luggage belts were not being used. It looked like there was only 1 crew serving .3 arriving flights.

Liked: staff, no delays, Could use some improvement: Food, comfort, cleanliness, lack of chargers on the DCA -> DSM flight

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.
