Heathrow offers more frequent flights, especially when travelling to Buenos Aires, the capital city. Flights from Heathrow International are also usually the cheapest and quickest option when picking this route.

Jorge Newbery Airport (AEP) in Buenos Aires is the main domestic airport in the country and offers numerous flights to most cities worth visiting, as well as neighbouring countries.

Airline reviews

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

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.

The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

We boarded so late it caused us to miss time at Foz. No real information was provided to the passengers waiting.

Please guy check the food I almost end up to the hospital

Just some cookies and water. There could be other options for food.

I do not speak Spanish or read in Spanish When asking for help, people were hard to find they spoke quickly and pointed a lot directions for where to go and what to do we’re unclear. Which made my traveling uneasy.

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

I flew in business a couple of months ago, it was great, tried again in economy, it is the cramped seat I have ever been into, for an overseas flight across the atlantic it is inhumane to put passengers in such cramped space. Other than that, everything ok. Took a second flight from Madrid to London, also economy and it was roomy and perfect.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

They didn't even give us water, everything was sold

Terrible experience - we won’t be flying with Air Europa again

No frills airlines. Tickets were reasonably priced for a short-term booking. But comfort is a big issue.

Food was terrible. No breakfast. Will not use this airline.

I travel on a monthly basis and I’m not a stranger to budget airlines. I never complain about anything, it just about adjusting you expectations to what you paid for and you will get, but these flights (2) with Air Europa Miami - Madrid - Athens were a terrible experience. Both flights had a significant delays and multiple gate changes. At the checking they used a hand scale to weight your carry in, it cannot be more than 10 kg , even it fit on size.Luckily mine was ok . The food was inedible. The staff service was ok, but you can totally tell they do not care about much and show little customer service culture. I think this was my last trip on Air Europa. Actually the price was almost the same than other major airlines, I just took this one because I needed to depart late at night.

Probably will never use this air line again. Rude miserable staff. Uncomfortable seats.

Impossible to check in via the App. Kept on getting emails offering upgrade. When followed through not available. Wasn't any food anyway.

After landing in Paris every one in the plane had to get on a bus which was packed and every Covid protocol was violated. There was no social distancing. It was disappointing. There was an empty bus right behind us. A few passengers asked to get on it to keep some distance between people but the driver refused. Probably you do not care.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Give at least coffee or juice as it is an international flight.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

A flawless trip, great experience. Keep up the good work!

This was my first time flying with you guys and my very last! This was the most horrible experience!!! There was not even tv in the plane! How cheap can this airline be!!! I paid so much for my suitcase!!! I would never fly with this airline again! The crew are very rude!

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.

The usb plugs for charging your phone didn’t work, the seats were coarse and hard. Not very comfortable. No inflight WiFi

No food, terms when selling are not clear. To pricy for the service in general

please see previous response; it covers the whole travel trajectory.

I enjoyed it! In that case, I should have been offered this choice. On my first trip to Miami, I was asked to pay $320 for my luggage just for getting it totally broken. I cannot accept this situation at all!!!!

They charged for WATER on a SIX hour flight!! never again!

The temperature was cold and the food that we had to pay for was awful. The crew didn’t even offer a free glass of water. It was a long, expensive and uncomfortable flight.

My international flight from LAX to Argentina had one free check in bag included in the price I paid, however your crew in LAX made me pay $95 USD to carry it on! Please note I had only on small size luggage (carry on size) and one backpack. I demand my $95 USD back that you guys charged me illegally in LAX.
