Premium demand meets a fuel-price wall

01 Running thesis

A better airline, still a cyclical one

LATAM has come out of the pandemic as a stronger airline group. Demand is high, capacity is growing, and Q1 2026 adjusted operating margin hit a company record 19.8%. The business is also moving upmarket. Premium passenger revenue reached 27% of passenger revenue, up from 23% for 2025.

That mix matters because premium travelers are usually less price-sensitive than bargain travelers. It can help LATAM sell seats at better prices and reduce some of the old seasonality in air travel. LATAM PASS also gives the company a large direct customer base, with 55 million members as of Q1 2026.

The bear case is simple: airlines do not control their biggest shocks. Jet fuel jumped after Middle East conflict, and management suspended full-year guidance while warning of more than $700 million in added Q2 2026 fuel expense. Currency swings, supply chain delays, and political rules in key markets can also hit results quickly.

So the thesis is not that LATAM is risk-free. It is that LATAM is showing better demand quality and better cost discipline than the old airline stereotype. The open question is whether those gains can survive a sharp fuel spike and a more active policy backdrop in Peru and Brazil.

May 2026Q1 2026 strengthened the premium and margin story, with record 19.8% adjusted operating margin and premium revenue at 27% of passenger revenue. The same update raised fuel risk sharply, as management suspended full-year guidance and warned of more than $700 million in added Q2 fuel expense.
Mar 2026The 2025 Form 20-F confirmed $1.46 billion of net profit and large shareholder returns through dividends and buybacks. It also added risk detail on grounded aircraft, Peru politics, and tax relief for Azul and Gol.
Feb 2026Q4 2025 showed premium revenue at 23% of passenger revenue for the year and LATAM PASS near 54 million members. Management also said stronger local currencies are net positive for unit revenue after costs.
Nov 2025Q3 2025 kept the operating story strong with an 18.1% adjusted operating margin and a new Embraer E2 order for Brazil. Risks rose from softer South America to U.S. leisure traffic and a possible Brazil rule on free bags and seat selection.
Jul 2025Q2 2025 showed premium demand growing faster than total passenger revenue and a record Q2 adjusted operating margin of 12.9%. The company also refinanced expensive debt and expanded its buyback plan.
Apr 2025Q1 2025 delivered the highest first-quarter profit in LATAM's history at $355 million. Management raised 2025 margin guidance and added Argentina to the Delta joint venture.
Mar 2025The 2024 Form 20-F showed passenger traffic growth of 16.8%, ahead of 15.1% capacity growth. It also confirmed that the Delta joint venture had added six new routes and more frequencies.
Jan 2025Q4 2024 confirmed strong execution and deleveraging to 1.7x. The board also considered a share buyback of up to $150 million, while Colombia overcapacity and engine issues remained risks.
02 Business model

Seats, freight, and network scale

LATAM makes most of its money by selling seats on domestic and international flights. It also sells cargo space in the belly of passenger planes and on dedicated freighters. In 2025, passenger revenue was 87.0% of total revenue, cargo was 11.4%, and other operating income was 1.6%.

The company’s edge comes from route scale across South America, plus long-haul links that connect the region to North America and other markets. The Delta Air Lines joint venture adds more network reach, and Argentina was added to that partnership in April 2025.

Costs still decide a lot of the profit story. LATAM reports adjusted passenger CASK ex-fuel of $0.043, meaning the cost to fly one available seat one kilometer before fuel. Management expects future efficiency gains to come more from software, maintenance tools, and cargo digitization than from a major hardware change.

The model breaks when outside costs outrun ticket prices. Fuel, local currencies, airport fees, and aircraft delays can all move faster than LATAM can reprice seats. That is why the premium shift is important, but not enough by itself.

03 Product portfolio

What LATAM sells

Cash cow

Core passenger flights

This is the main business, covering domestic Brazil, Spanish-speaking domestic markets, and international routes. 2025 passenger revenue rose 12.3% to $12.6 billion.

Growth engine

Premium cabins

LATAM is adding suite doors in business class, wider WiFi, and a Premium Comfort Class planned for long-haul routes in 2027. Premium revenue reached 27% of passenger revenue in Q1 2026.

Steady

LATAM PASS

The loyalty program is the largest airline loyalty program in the region by management's description. It had 55 million members as of Q1 2026 and helps LATAM sell more directly to repeat travelers.

Steady

Cargo

Cargo uses both passenger belly space and dedicated freighter aircraft. In 2025, cargo revenue was $1.65 billion and grew 3.4% from 2024.

Option

Regional and long-range fleet options

LATAM has an order of up to 74 Embraer E195-E2 aircraft to deepen regional reach in Brazil. Airbus A321XLR aircraft are expected from 2027, but Peru connection fees may change where they are deployed.

The mix uses FY 2025 total revenues from the 2025 Form 20-F: 87.0% passenger, 11.4% cargo, and 1.6% other operating income. Passenger remains the center of the story.

05 Risk factors

What could go wrong

Fuel spike outruns ticket pricing

High impact · High odds

Jet fuel is the clearest near-term risk. Management warned that Q2 2026 could carry more than $700 million of added fuel expense if jet fuel stays near $170 per barrel. Even premium demand may not fully absorb that shock.

We watchTrack jet fuel prices, management guidance, and whether PRASK rises enough to offset fuel cost.

Peru fees weaken the Lima hub

Medium impact · Medium odds

LATAM planned to deploy incoming A321XLR aircraft in Lima, but a new Peru connection fee changed the math. Management called the fee bad public policy and said it is reviewing where those aircraft should go. A permanent shift away from Lima would change the network plan.

We watchWatch A321XLR deployment comments and any change to Peru airport or connection fee policy.

Brazil competition gets fresh support

Medium impact · Medium odds

Brazil is a major domestic market for LATAM. Azul and Gol entered agreements with the Brazilian government to cut tax debts by about 42%, which could give them more room to compete. LATAM says ultra-low-cost carriers are currently cutting capacity, but that can change.

We watchWatch domestic Brazil capacity, fare trends, and Azul and Gol restructuring updates.

Currencies swing against results

Medium impact · High odds

LATAM reports in U.S. dollars but earns and pays many items in local currencies. The Brazilian real is especially important. A stronger local currency can help revenue in dollar terms, but it can also lift some local costs.

We watchTrack BRL movement against the U.S. dollar and LATAM's dollar-based RASK commentary.

Aircraft and engine delays limit capacity

Medium impact · Medium odds

Supply chain problems are still a real limit for airlines. At year-end 2025, 13 Airbus Neo aircraft, equal to 3.5% of LATAM's fleet, were grounded due to Pratt & Whitney engine inspections. More delays could keep seats out of the market when demand is strong.

We watchWatch grounded aircraft counts, OEM delivery updates, and engine inspection timelines.

Brazil rules cut ancillary fees

Medium impact · Medium odds

A pending Brazilian law could require free carry-on baggage and free seat selection. That would pressure ancillary revenue, which is extra money airlines make beyond the base ticket. The impact depends on the final rule and how LATAM changes fares.

We watchWatch the Brazilian baggage and seat selection bill and LATAM's ancillary revenue comments.
06 Quick answers

In one breath

What does LATAM Airlines do?

LATAM runs passenger and cargo flights across South America and to international destinations. Most revenue comes from passenger flights, with cargo as a smaller but useful second business.

Why is premium travel important for LATAM?

Premium travelers pay more and tend to be less sensitive to price changes. LATAM's premium revenue share reached 27% of passenger revenue in Q1 2026, which helps margins if demand holds.

What is the biggest risk for LTM stock?

Fuel is the biggest near-term risk. Management suspended full-year guidance after a jet fuel spike and warned of more than $700 million in added Q2 2026 fuel expense.

How strong is LATAM's balance sheet?

The company reported net leverage of 1.3x, which is low for an airline with large fleet needs. That gives management room for shareholder returns, but airlines can burn cash quickly when fuel or demand turns.
