Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

The flight crew was the worst I've experienced. If they worked for me, I would fire them immediately. They never smiled, they seemed angry and avoided passengers as much as possible. The food was not edible, and my luggage was lost. I will never fly United again!!!

Fought with Lufthansa was poor, seats are uncomfortable, food was bad and luggage did not arrive to IA

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

I was assigned the last seat in the last row directly in front of the bathrooms at check-in when there were plenty of open non-upcharge seats available. That seat should not be given out unless it’s the absolutely last one available. I had traveled/waited for over 10 hours and to get that seat on my final of 3 flights from Rio was a slap in the face.

Was given all 3 boarding passes. Was refused boarding to Brasilia in Miami even though I had up to date Brazilian Visa and US passport. Had to return to Phoenix as trip was cancelled. Waiting for refund of the fare. Missed my son's birthday and visit with him and his wife.

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

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.

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.

They are not ready for international flights, poor service and food, no screen info on the seat.

Gol has an interesting choice of words. When they say “priority access”, this means you’re boarding on the seventh or eighth group.

They are a mess. It appears they hired a third party to staff their check in desk and simply did not train them. I will avoid flying with them in the future. It took 50 minutes for them to check in 3 parties on front of us. On the way back. It took just under one hour for our luggage to show up...

The aircraft is really unconfortable. Even the premium class the seats are narrow and hard. There are no screens to watch movies, we have to use our phones. The food is ok in the premium class and really BAD in the economy class. The crew is lovely. I do not intend to travel Gol internationally if I can possibly avoid it.

There were three people in an economy seat in my row, but the row in front of me, which had the same class of service only had one person. I could barely move and the person in front of me slept on all three seats. If you had moved one person from my row to the row in front, the configuration would have been two on each row with the middle seat empty

It’s a new plane, but the most important detail is that the economy class seat doesn't recline—it’s completely fixed. The only one that reclines is in Comfort Class.

Better seats, allow us to upgrade, terrible website, poor telephone service, better equipment

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.

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

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

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Felt very cramped in the back of plane. There was an hour delay for take off sitting on the runway, but we did arrive on time. They charge $120 for carry on bag and backpack at the airport its ridiculous.
