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

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

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

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.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

horrible service, food was an embarrassment, no charging for cellphones, stay away

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

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

Did upgrade, travel in business it was great (more room I could sleep)

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

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.

Poor, the airline was not able to help me move flights.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

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 confusing with a delayed flight because there was no English translation

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I was not able to get on the flight due to delays out of Philadelphia. I arrived in MIA at 10:30pm and there was no one at the GOL Desk. Is there any flight credit available for this flight?

I have a hand injury and the flight attendant denied to help me with luggage, she said "she couldn't help me because I should manage my own way to put the luggage on the plane" SO RUDE

I had two around 6 hours flight and they did not even offer water to us.

Overall it was good. The food was not great quality and seats were very uncomfortable. But overall the staff was very friendly and helpful.

We flew with Avianca, some how they are not n sync, making the process a bit uncomfortable.

Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.

Flight on time, check in and flight attendants courteous and helpful. Smaller plane for international flights, tight space, no comfortable.

the boarding staff were incredibly officious. our carry-on case was borderline within dimensions but staff were not prepared to show ANY flexibility even though many others with larger carry-on luggage were allowed to board. we were understandably furious but the staff were incredibly disrespectful. we called the supervisor who eventually agreed to look on board the plane to see if there was room for our case (one case between 2 of us) and reluctantly agreed to allow us on. The staff on board were excellent though and realized we had been treated badly and were very helpful both in finding a place for our case, some distance from our seats, and helping us to retrieve it when we landed. We are regular travelers on Gol and have Diamante status and had chosen the better Conforto + seats, so we expected better treatment from the ground staff. Also the cabins are of a size that will only fit 3 cases of normal size with a large gap of about 30cm of wasted space. If our case were deemed to be oversize, which I dispute, the extra 1cm would not have made the slightest difference.

I did not like the way that baggage fees were charged. When I signed up for the flight, I knew that there were bag fees. However, the bag fees were so confusing that it felt like I was paying for overweight bags rather than just for having brought a bag with me. Also, the bag fees were based on the pair of tickets rather than per person. It seems to me that it should be first bag fee for passenger 1 and then first bag fee for passenger 2. I eventually got away with only paying $100 for two bags, but it was a struggle to understand the process. As for the flight, the seats were the standard uncomfortable seats that are on most Boeing aircraft. The airline aims to accommodate the standard height people, so us tall people are stuck. There was never an option to upgrade for leg room. It did not appear that there were any seats on the whole plane that had a little more leg room to even try to get. Other than that, I completely ignored the food for this red eye flight. I am not one to eat "dinner" at 2 am. They did not offer any drinks in the morning before landing. I recommend that you bring a bottle of water on board.

Lost luggage, people are not very nice to help you , I was just instructed to fill out a baggage claim online, they were not helpful when I had additional questions after I completed the form on my phone.

Not even water is offered on the flight. You cannot lean back on the seats and the seats are so narrow you can’t avoid rubbing elbows with the person next to you.

I couldnt recline the seat. Other than that crew was very attentive and helpful. Thsnk you

I had to go to the boarding counter for them to enter my return flight as it’s not with Avianca. There was a long queue as there were lots of people being called to the counter.

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

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

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve

Usb plugs for charging your phone does not work in every flight. uncomfortable chairs even in higher categories.

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.
