American Airlines 777-300ER Business Class Review (2026): New York to Buenos Aires

American’s Boeing 777-300ER is still one of its most complete long-haul aircraft, with Flagship First at the front and a large Flagship Business cabin behind it. After flying the same aircraft in Flagship First from Buenos Aires to New York, I returned in Business Class, which made this a useful back-to-back comparison of the two cabins.

I booked this one-way flight for 60,000 AAdvantage miles + ~$100 in taxes. That is a very solid rate for a lie-flat Business Class seat on an 11-hour overnight flight, especially when cash fares on this route can be extremely high.

Overall, nothing about the flight was exceptional, but the product does the job well, particularly when booked with points or miles. The weakest part was the service: rushed, cold, and at times genuinely rude. My guess is that the crew was having a rough night for reasons I couldn’t see.

Other than that, the seat was solid, the mattress pad made sleeping much more comfortable, and the food was tasty. Let’s get into the details!

How I Booked This Flight

American AAdvantage has been one of the programs showing the most useful premium-cabin availability out of Buenos Aires lately, which is why I’m keeping it more active. Although American prices its own flights dynamically, there are still a reasonable number of seats at the lowest price point.

A round-trip Business Class fare between Buenos Aires and New York is often around $5,000, but when lower award prices are available you can book the same trip for ~120,000-160,000 AAdvantage miles + ~$200 in taxes round trip. That works out to roughly 3-4 cents per mile. Our AAdvantage guide covers current award pricing, partners, earning, and elite status.

Check-In & Security

My trip actually started in Boston, where I checked in through the priority lane and took a short hop on an Embraer 175 to position at JFK. That flight was delayed by more than two hours, which at least gave me time to work from the Admirals Club in Boston.

American Airlines Greenwich Lounge at JFK

Once I landed in New York, I had about two more hours before my flight. I headed to the Greenwich Lounge, which is the main lounge for Flagship Business passengers at JFK Terminal 8. On my previous leg, since I had upgraded to Flagship First, I could use the Chelsea Lounge, which is smaller, quieter, and more exclusive.

The Greenwich Lounge is quite large. It is not as impressive as the Delta One Lounge at JFK, but there is plenty of space and a good mix of seating and dining areas. The food is solid, although you shouldn’t expect anything fancy: a salad bar, cheese and cold cuts, plus a handful of hot dishes such as meatballs, burgers, curries, and other finger foods.

I grabbed a quick bite and, since the flight overlapped with a FIFA World Cup match involving my home country, watched the first half while sitting by the window.

Boarding

The gate was only a three-minute walk from the lounge. When I arrived, though, the area was absolute chaos: it was full of people, there were no clear lines, and no staff were organizing the crowd. When the announcements finally started, passengers were called by zone, but it was still difficult to sort through everyone and reach the gate.

Boarding itself was biometric, using a face scan. There was no need to show a passport or boarding pass unless something went wrong, so the process was quick and smooth once I reached the reader. This was the fourth airline where I’ve tried biometric boarding, after Delta, United, and KLM.

Flagship Business Cabin & Seat

My seat was 9A, on the left side of the aircraft and roughly in the middle of the Flagship Business cabin. The 777-300ER has a 1-2-1 layout in Business Class, so every passenger gets direct aisle access. To my surprise, the cabin felt fresh and tidy, and there was plenty of space in the overhead bins.

Several amenities were already waiting at the seat: a pillow and blanket, slippers, and a mattress pad. The cushioned seat cover is a nice touch that some airlines have stopped offering in Business Class. It seems to be one of those trends that comes and goes, including at airlines such as Lufthansa and Avianca. There were no pajamas this time.

There was also a bottle of water, headphones, and a special U.S. Soccer amenity kit created for the 2026 World Cup.

The tray table folds out from the side console and is large enough for dining or working. The same area holds the seat controls, handheld IFE remote, a small storage compartment, and the bottled water.

Amenity Kit

The amenity kit was a limited-edition U.S. Soccer design, introduced for the 2026 summer tournament as American is the Official Airline of U.S. Soccer. The clear bag can be reused as either a belt bag or a crossbody bag. Inside were U.S. Soccer socks, an eyeshade, earplugs, a dental kit, Joanna Vargas eye patches and a refreshing hand towel, hand and body lotion, lip balm, and after-sun cooling gel.

IFE, Headphones & WiFi

The headphones are very good, which helps explain why American has offered the same setup for so long. You get Bang & Olufsen over-ear headphones with effective noise cancellation, presented in a hard case. They are clearly better than typical airline headphones and comfortable enough for a full movie, although they can start to feel heavy after long periods.

The IFE screen folds into the seat shell in front and releases with a latch. The system does the job, but it is easy to tell that it is getting old. This aircraft uses an older Panasonic setup that feels laggy and short on features compared with newer cabins.

The screen is touch-enabled, and there is also a handheld remote in the left-side panel. The content library was quite reasonable, with plenty of recent movies.

Paid WiFi was available through the Panasonic portal at aainflight.com. It cost $29 for a two-hour pass or $35 for the full flight, with no complimentary tier in Business Class. I would argue that long-haul WiFi is something airlines should include for premium passengers. In that regard, SAS does a great job of understanding what Business Class travelers need.

Takeoff

Once I was settled, the crew came around with welcome drinks and I went for a glass of champagne. The cabin was surprisingly quiet during boarding, as most people were following the football match. The flight deck was kind enough to give an update every ten minutes or so, announcing goals, fouls, and the score. It was a nice touch.

On my outbound leg, I managed to get one of the pilots’ union trading cards, but not one of the centennial-edition cards American had recently announced.

When I asked the crew if I could check with the pilots, they had no idea what the cards were and told me the pilots were busy. I asked again at the end of the flight and was told that none were available. The rollout still seemed patchy following the announcement.

After a long boarding process, we pushed back and headed toward the runway. We had lost our departure slot, though, and had to queue behind about 15 other aircraft. That meant waiting an extra 40 minutes. Passengers complained out loud; most were tired and just wanted to recline their seats and sleep.

At least the delay allowed me to watch the rest of the match on my phone. We eventually took off into the night, and the cabin remained dark for most of the flight.

Dinner

The centennial Flagship Business menu was waiting at the seat during boarding. I had already pre-ordered my main dish online, but the printed menu covered the full dinner and breakfast selection.

From the moment I boarded, I felt that something was off with the crew. Maybe they were tired or something had happened before the flight, but the atmosphere felt cold and grumpy. The meal service confirmed that first impression.

This was completely different from my previous flight in Flagship First, where I had one of the most charming and kind flight attendants I’ve ever met. On this flight, the service was awful and nowhere close to what you would expect in Business Class.

First, everything was rushed to the maximum. I can understand moving quickly on a late-night flight, when the crew wants to finish dinner and let everyone sleep. Meal services on airlines such as KLM or Lufthansa can sometimes take more than two hours, which is not ideal either. But this went well beyond being efficient.

Service began with a hot towel, followed by warm nuts and a drink.

There was almost no dialogue or eye contact. Plates were placed on the tray table in a clumsy, almost rude way, and food or drinks were spilled on me three times during the service. Drink orders were taken by shouting a single word: “DRINK?” The whole thing felt more like a parody than a real premium product you would want to buy.

Luckily, I had pre-ordered the “Centennial Edition” sliders online, and they were actually pretty good. The tray also included a green salad and a grain salad. That was the bright side: the food did its job. For dessert, I chose the cheese plate with crackers.

According to the timestamps on my photos, the entire dinner took exactly 30 minutes.

Lavatory & Cabin

There are several lavatories for Business Class, including two next to the galley in the middle of the cabin. They looked good, were reasonably sized, and stayed tidy. There were no extra amenities inside, such as toothbrushes, toothpaste, or shaving kits.

Sleeping in Business Class

After dinner, I prepared the seat for some sleep. Fitting the mattress pad over the seat is straightforward. You can also ask a flight attendant to set it up for you, although given the interactions so far, I didn’t dare ask this time.

With the mattress pad in place and the seat fully reclined, I managed to get a solid few hours of sleep and woke up a couple of hours before landing.

Breakfast

About an hour and a half before landing, the crew started serving breakfast while the cabin was still dimmed. I went for the traditional cheese omelette, which came with a fruit bowl and a pastry. The coffee took forever to arrive.

The service was again rushed and had the same cold tone as dinner. It is rare for me to have this kind of experience on American, so my guess is still that the crew was simply having a rough night.

Arrival

There were severe thunderstorms over Brazil and Argentina. As we approached Buenos Aires, the pilot announced that we would have to fly around several storm cells, adding another 40 minutes to the journey. You can see the detour on the screen below.

The final approach and landing were extremely smooth, though, and the weather at Ezeiza was sunny and clear.

Final Verdict: Is American’s 777 Business Class Worth It?

For 60,000 miles + ~$100, this was still an extremely solid redemption. American’s Flagship Business gets you a lie-flat seat, a mattress pad and good bedding, excellent headphones, decent entertainment, and access to the Greenwich Lounge. Nothing about the product is extraordinary, but it does the job. With good, attentive service, I would rate it 4/5; this particular flight earned 3.5/5.

The calculation changes if you have to pay cash. The other main U.S. options from Buenos Aires are Delta and United. Delta’s experience feels more premium, from its outstanding lounges to the seat and dining, although in the searches I’ve seen it can be around 30% more expensive. United is more on par with American. Another option is to connect through Miami on one of American’s 787s, which has a different Business Class seat.

On this particular flight, I got unlucky with the crew. I’ve flown American many times on this route, and it is rare to experience service this poor. While U.S. airline crews can feel louder and more casual than their European or Asian counterparts, they are usually friendly and warm. I’m going to assume this was a one-off and that there was an internal reason for the mood onboard.

I still consider this one of the best options between Buenos Aires and the U.S., especially when award availability appears through programs including AAdvantage, Atmos Rewards, and even GOL Smiles.
