Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

The cabin temperature was nice and cool. The wifi was not working.

As previously noted, this flight was great: departure was timely, the crew was friendly and attentive, and wifi connectivity was seamless. In particular, I appreciated that the flight attendant just told me to stow the laptop right before takeoff/landing, and trusted me to do so (which I did!).

Left a few minutes early. Got in 15 minutes early. Very attentive service on board. Very organized boarding.

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

Awesome! On time flight, early arrival, and a complimentary upgrade!

The food is terrible I ask for water never got transport my mother we’re late and my sister from Lima was the worst waiting to long for wheelchair

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

Copa staff at PTY and one particular crew member were unhelpful & rude.

A lot things happened in this trip.The fly should be less stress.

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

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

Some of the Air hostesses are not that friendly. Need improvement

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

we did a return flight from Paris CDG to SFO. This trip was much better than the departing flight SFO to CDG. The food was better quality, the crew was nicer, and the interior of the plane seemed cleaner.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

We got to get extended leg room in Econ plus that was great. It was nice having our own dietary needs met with our meals, and the connecting flights had it as well. Only negative were the seats my bottom was/is really sore after a ten plus hour flight. Those seats are horrible, understandable for as many people use them. So we are going to purchase a gel seat pad.

Flight to Japan was was better across the board than the return to USA. Entertainment: Movie selection was old and not to my liking. Way too many woke choices. Not enough selections for sports or drama. Service: some of the crew were great. Not all. I paid for business class. a premium. Some of the crew thought they 'had' t do there job instead of wanting to serve and be polite. Food: Way to Japan was good. Way back to USA bad. Boarding: Wat out did not offer Business only; had to go thru general. If you pay for business, you should get business perks. Suggest you look for other than United for travel to Asia

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

The head flight attendant made the trip excellent. He was very accommodating.

The economy seats on the 777 was not as cramped as I had feared, but the food was terrible.

Terrible experience! delay 2 time and say i dont have ticket

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

Flight was on time. Cabin attendants made no recognition of my name or being an Advantage Executive Platinum member.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Crew was rude, almost 6 hour flight after horrific customs re entry line and near flight miss (unable to bug airport food) without food offerings.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

They are always late and seats was also not having working charger

did not have enough meal for first class passengers so offer us snack

We were upgraded to Business Class. So comfortable with great service and food options

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral and avianca lost my check in luggage

only a bag of chips and a bottle of water in business class was served

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

We waited for one hour to deboard the plane after landing. That could be better

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

I like the crew they're very friendly. I don't like. on five hour flight they not offered snacks. Any drink. Not even coffee

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Horrible experience. Flight cancelled. Arrived at destination 12 hs later. No one gave us an answer or any information. Very very poor service. We won’t ever travel again with Avianca
