Delta Launching Boston To Sao Paulo Flights, Replacing LATAM

Delta Air Lines is launching a new route on its own metal (thanks to @IshrionA for flagging this), though only for a limited time…

Delta will fly from Boston to Sao Paulo in early 2025

Between January 6 and March 27, 2025, Delta is operating a 3x weekly flight between Boston (BOS) and Sao Paulo (GRU). The 4,790-mile flight will operate with the following schedule:

DL165 Boston to Sao Paulo departing 9:00AM arriving 8:45PM
DL164 Sao Paulo to Boston departing 10:45PM arriving 6:40AM (+1 day)

The southbound flight is blocked at 9hr45min, and will operate on Mondays, Thursdays, and Fridays, while the northbound flight is blocked at 9hr55min, and will operate on Wednesdays, Thursdays, and Sundays.

While the outbound flight timing is great in terms of aircraft utilization (since the plane can turn right around in Sao Paulo), the daytime flight isn’t necessarily preferred by many business travelers, and it’s also not great for connections.

Delta will use an Airbus A330-300 for the service, featuring 282 seats. This includes 34 Delta One (business class) seats, 21 Delta Premium Select (premium economy) seats, 24 Delta Comfort+ (extra legroom economy) seats, and 203 Main Cabin (economy) seats.

It would appear that Delta is simply replacing the service of its joint venture partner LATAM in the market for a period of roughly three months. LATAM has operated this route since 2018. Delta’s new service has identical timing to LATAM’s service, which is why it seems like it’s a replacement. Meanwhile LATAM will operate this service through early January, and again as of late March.

It’s interesting to see Delta replacing LATAM in the market

Delta owns a stake in LATAM, and on top of that, the two airlines have a joint venture between the United States and much of South America. With a joint venture, airlines can coordinate schedules and fares, and can also share revenue.

We often see joint venture partners replace Delta in some markets, which is logical enough, since Delta has a higher cost structure than most of its partners. For example, we’ve seen Delta axe service between Los Angeles (LAX) and London (LHR), and instead that route is exclusively operated by partner Virgin Atlantic.

So in this situation, why is Delta replacing its joint venture partner LATAM, which almost certainly has a lower cost structure? In this case it seems easy enough to figure out:

  • US airlines can’t get their hands on enough wide body aircraft for their summer schedule, given the amount of transatlantic demand; however, the first three months of the year are the absolute slowest across the Atlantic
  • As a result, Delta presumably has some spare aircraft, so the airline needs to fly them somewhere
  • Meanwhile in South America, those same months are peak season (given that it’s summer in the Southern Hemisphere), so I suspect LATAM can better utilize its aircraft for other routes

All of this seems like a logical enough development. If Delta permanently replaced LATAM in this market, then I’d be a bit confused. But with Delta just taking over the service during its slowest period for long haul travel, this makes sense.

LATAM has better ways to utilize its planes in peak season

Bottom line

Delta will operate flights between Boston and Sao Paulo in early 2025, replacing the existing service by joint venture partner LATAM. It may seem confusing to see Delta get into this market for just a few months, especially given that Delta has a higher cost structure than LATAM. But it’s easier to make sense of when you look at the big picture, and consider the other places LATAM can fly planes that time of year.

What do you make of Delta launching Boston to Sao Paulo flights?

As part of their growth between the two airlines, here is my short list of routes that both airlines should add in the near future. ATL - Medellin (Delta) ATL - Brasilia (Delta) Lima - Boston (LATAM) Any routes that I missed, add them to list.

Boston (and environs) hosts the largest brazillian community in the US and the largest concentration of brazilans outside of Brazil. Jan-March are the Summer months in Brazil, with awesome weather, carnaval, beaches and everybody having a good time. I think this route will work for Delta.

‘Delta is by far in the best position among US airlines - and among many global airlines’ How can Tim even try to put Delta in the same league as global airlines? Just focusing on U.S. airlines Delta flies to 89 international destinations, American flies to 92 international destinations and United flies to over 120 international destinations. As Ben recently pointed out in an article about United, he says that United is truly the leader among the U.S. airlines when it comes to being a global airline as it flies to more international destinations than any other U.S. airlines. At least, United tries new routes and makes it worthwhile for the customers while Delta only looks after its bottom line. ‘ Delta is the only US airline that is buying widebody aircraft from Airbus. Everybody else is dependent on Boeing and their problems.’ Yes, which shows Delta’s hypocrisy when it joined other U.S. airlines to talk smack about the ME3 when back then Delta only bought foreign made aircraft and back in 2017 it had the audacity to talk about protecting American jobs when it bought a lot of airplanes from Airbus. Yes, now it is a different story as Boeing is going through its own troubles but I just wanted to point out Delta’s hypocrisy and no matter what Delta did or does there will always be Tim with his own Delta poms poms cheering them to the end.

Let's break this down for once. "If the flight works for LA with the current timings, it works for DL. They have a JV. There are connections at BOS and certainly on the GRU end." Great reaction, to the point and on topic. You could have stopped here. "As for aircraft availability, all US airlines use more widebodies in the summer than in the winter." Ok, nice addition, nice to mention, but a bit like kicking in an open door, to be honest. It's not exactly new information. "In addition, DL will receive 14 new Airbus widebodies this year - more than twice the number of 787s that AA, UA and HA will receive from Boeing." Here we go again. A completely off-topic rant and somehow UA and AA need to be involved. Even worse, they need to be shat on and made look bad - even about things beyond their control and which have literally nothing to do with the topic. It's as if Timmy only gains self worth and self confidence by kicking others down instead of climbing up by himself. Very sad. "Most of DL's new widebodies are coming or came after the summer so were of no use during the most peak summer period." Irrelevant. "DL is beginning conversion of the ex-Latam 359s to the new DL standard 35H configuration." Irrelevant. "They are also retiring several 767s between now and the spring but they still have more widebodies during the winter that they need for their international schedule and still have some for 2025 growth - in addition to the 11 confirmed Airbus widebodies they will receive in 2025 although some could also be received in the 2nd half of the year and not usable for the peak summer period." Since this is about a swap of metal for about 10 weeks, since this involves an A330 and since this topic has absolutely nothing to do with anything that might happen later on in 2025, nor on completely different routes, I'd call it off topic. "Competitively, I believe with this addition, DL will overtake UA as the 2nd largest US airline at GRU even on its own metal." Irrelevant and speculation. Being the carrier with the second most 'US metal' at some airport doesn't say anything, really. It's about a temporary 10 week aircraft swap, it's not a long term strategic investment that's being discussed. Besides, given that the 3 US legacy carriers fly to and from different hubs, have different strategies and appeal to different audiences, making literally every route or aircraft a competition is truly apples and oranges, or rather complete bollocks. "DL appears to have a good plan to use its extra widebodies during the winter in markets other than to Europe is also operating double daily ATL-EZE and ATL-SCL for a couple months during the winter as well in addition to their increased service to the S. Pacific." Again, off topic and irrelevant here. This is about a short term aircraft swap on a route to Brazil. "There are other routes to S. America which DL could take over from LA even on a seasonal basis if this works." They could also ask Air Belgium for some nice wet lease agreements if they're shorthanded, for example. Again, off topic and speculation, there's no incentive to assume this may be considered. I side with Julie and many others here: please seek help.
