KAYAK’s top tips for finding a cheap flight from Los Angeles to Buenos Aires

  • When flying out of LAX, ensure you get to the airport 3-4h before your scheduled departure. This is because the airport is always busy, and the security lines can be extremely long. Arriving early helps you avoid any risk of missing your flight.
  • If you are leaving your car at the LAX Airport parking, compare the rates offered by airport parking and other off-site parking lots. In most cases, the off-site parking lots charge significantly lower rates and provide a free shuttle.
  • Ontario International Airport (ONT) is less than 50 miles away from LAX. If you want to avoid the long lines at LAX, consider booking flights that fly out of Ontario International Airport.
  • Consider booking direct flights instead of connecting flights to make your trip more sustainable. This is because connecting flights tend to have higher carbon emissions due to repeated take-off and landing.
  • Buenos Aires is served by two major airports, Aeroparque Internacional Jorge Newbery (AEP) and Ezeiza International Airport (EZE). AEP Airport is the closest to Buenos Aires. Therefore, if you want to be near the Argentine Capital, consider booking flights that land at Aeroparque Internacional Jorge Newbery.

Delta flight was on time, seats were comfortable, and crew was nice.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

We departed and landed on time, the aircraft was clean and comfortable, the crew were lovely. Online checkin worked well and the self service bag drop at the airport worked well. The a/c was an Airbus A330 and has been fitted with a good entertainment system with lots of choice in many languages. The price I paid for the flight was competitive with other airlines apart from the budget carriers, none of whom I was familiar with so I stuck to an airline I have used in previous visits to South America.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

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.

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

I liked everything, this was classed as premium economy but it was much better than Lufthansas business class. Lovely staff, comfortable plane and an excellent seat arrangement. A very pleasant surprise.

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

Friendly staff, It was the first flight out for our plane, so had to be deiced from the frost. Only delayed a few minutes,

Staff encountered friendly and helpful. Flight delayed 1 hour due to mechanical issue, but made it through Atlanta immkgration and security in plenty of time,

We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

My flight delayed and i misss the connection they send me to orlando no to tampa i have to pay a uber to my house

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

No headphones given for inflight entertainment. I missed my flight from the previous day and the customer service agent tried to extort an additional $100.00 US from me for missing my flight. Really?!

It was good, plane is a bit older so seats are somewhat flat

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

Well the airline was fine. The only thing is I was charged for a checked in luggage. But when I reserved the ticket it showed a check in bag allowed. Who can I get in contact with for reimbursement.? The airline said I had to speak to whoever I booked ticket with.

Friendly flight team and seamless travel from one stop to next.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

British Airways staff are very polite and willing to help.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?
