Not enough legroom on flight. I was never offered the option of purchasing a seat with more legroom.

Not enough legroom on flight. I was never offered the option of purchasing a seat with more legroom.

I had an 9 hr layover continuing on to Ushuaia. I expected to have to get my luggage & do customs but I did not expect Aerolinas Argentinas to make me sit with all of my luggage for 7 hours in the entrance part of the airport before they would let us re-check our bags & get back in where there are seats. People were sitting on the floor everywhere.

This is the worst airline I have used in my 30 years of travel. The boarding process was an absolute nightmare with endless lines. It took 4 hrs to get to gate while in Bunoes Aires. Also, they change flight times and gates several times leading us to go to multiple gates. Never will fly this airline again

Aerilineas changed my airport from aero parque to Ezeiza and didn’t take care of my transport. Seats were mediocre and ground personal weren’t very helpful. Too bad that’s the only option to fly to El calafate. Bad service, bad company

Better snacks options for a 3.25 hour flight . There was only 1 choice - a fruit granola bar .

I liked the airport and aircraft crew. I disliked the fact that I and TSA pre check approved but this airline is not affiliated to the program. I was 4 hours befor departure and I barely made it to the gate. The airline does not allow to buy extra luggage online. After waiting 1 hour and 45 minutes to check in my luggage I had to do another line to pay my luggage with another hour of waiting. Only one airline person to process payment. This is ridiculous and I saw so many elderly people struggling in line waiting long hours.

everything, disorganized, the flight was delayed an hour and twenty minutes without any explanation

Solo diré que mi vuelo tuvo 5 horas y media de atraso. Jamás explicaron el motivo y se tomaban el tiempo del mundo para anunciar su siguiente retraso. Es más, esperaban a que llegara la hora de la supuesta salida para decir que se retrasaba nuevamente por otra siguiente hora. Implicó que tuvimos que pagar gastos extrae por el alquiler de nuestro auto y cuando le planteamos a customer services se desentendieron totalmente. Nada profesionales novel dios. Tengo tanto que decir en contra de aerolíneas argentinas que prefiero parar acá. Terrible, terrible, terrible

Boarding was efficient and painless. Food was not supplied. It will be good if some chips or biscuits can be provided.

I flew with a baby and the crew at night from Bs As to Atlanta were super helpful!

Very bad. Boarding was a caos and pick up luggage took more than an hour. There was no entertainment on board.

La aeronave estaba averiada, 4 horas adentro con diferentes problemas técnicos pero igual querían volar.

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...

Evifente que o melhor seria a Hol cumprir com ssua parte! Vendeu voo dirto Caxias do Sul a Florianópolis e depois alterou, fizemos voo Cxs. Congonhas, com conexão, alem de um atrazo, mais de 1:20 min. Está errado e isso é vender uma coisa e entregar outra...

Alimentação mto escassa. Pelo menos deveria dar a opção de comprar e o Wi-Fi pago.

A Gol precisa aprender comfazer desembarque. Está anos luz atrás em organização. Os comissários são muito atrapalhados.

Os passageiros ainda não estão habituados a respeitar o embarque por grupos, que é a melhor maneira de embarque, na minha opinião. Então faltou pulso para impor a regra de embarque e desembarque às pessoas.

Kiwi service was terrible they actually didnt make the reservation and their system showed that the reservation eas complete so I had to buy a ticket in the front desk at the moment at and exorbitant price.

A Gol melhorou muito desde a última viagem que fiz, muito bom, aeronaves bem conservadas, tripulação cordial. Gostei.

Online checkin - a mess, unable to do… At airport - terrible, only one agent for priority checkin.long wait for the line of folks..
