War and High Oil Prices Depress Airline Traffic, but Amadeus' Airline IT Contracts and Value-Added Capabilities Strengthen the Medium- to Long-Term Investment Case

Overview

The report compares Amadeus and Sabre by incorporating second-quarter 2026 results, changes in airline capacity after the Middle East conflict, fuel prices, regional flight recovery, customer migrations, and the potential impact of artificial intelligence. In the short term, war, high oil prices, and airlines' proactive capacity cuts are weighing on bookings and boarded passengers; over the medium to long term, the two companies show clear divergence due to differences in business mix, product capabilities, customer concentration, and balance sheets.

Core views

Amadeus remains the preferred pick. It holds leading positions in both airline distribution and Airline IT, with Airline IT and hospitality businesses contributing more than 60% of EBITDA and continuing to increase as a share. A new Altéa contract, British Airways' adoption of Altéa NDC, potential Nevio contracts, and structural cost reductions support earnings upgrades. The mature GDS business is more like a low-growth cash cow, but it can fund investments in Airline IT and Hospitality IT. Sabre has recently benefited from exposure to North America and corporate travel, with stronger bookings performance, but about 80% of revenue depends on GDS, the IT business is concentrated among a few large customers, and high leverage makes it more vulnerable in a future airline-cycle downturn. Artificial intelligence may weaken GDS bargaining power over the long term, but airline system transformations, commercial agreements, corporate travel processes, and behavioral changes are all slow-moving, so near-term disruption risk is limited.

Analysis framework

The report starts with airline capacity and fuel costs as macro drivers, tracks regional flight recovery and airline guidance, and then maps capacity changes to bookings and boarded passengers. At the company level, it compares revenue per booking, revenue per boarded passenger, customer migration, business mix, costs, and leverage, and accordingly revises earnings forecasts for 2026 to 2030. For valuation, Amadeus uses forward P/E, while Sabre uses forward EV/EBITDA.

Methodology notes

• Operating Driver AnalysisCapacity-Traffic-Revenue Transmission Framework

  Map changes in airline capacity to bookings, boarded passengers, and unit revenue

  The report starts from the impact of fuel prices and geopolitical conflict on airline schedules, and further analyzes changes in transaction volumes, unit revenue, and profits for airline technology suppliers.

• Event AnalysisCustomer Migration and Contract Win Analysis

  Assess the impact of major airline system migrations on future boarded passengers and market share

  The report incorporates a new Altéa contract with more than 40 million annual boarded passengers into Amadeus and Sabre forecasts from the fourth quarter of 2027, but clearly labels the judgment that the customer may be Lion Air as unconfirmed speculation.

• Relative ValuationForward P/E Valuation

  Determine the target price by multiplying target-year earnings per share by a forward valuation multiple

  Amadeus' €78 target price is based on 2027 EPS of €3.97 and a 19.7x P/E multiple.

• Relative ValuationForward EV/EBITDA Valuation

  Derive equity value using next-year EBITDA and an enterprise value multiple

  Sabre uses a 6.7x next-year EV/EBITDA valuation, down from 7x previously to reflect slower growth, resulting in a $1.75 target price.

• Scenario AnalysisGeopolitical Conflict and Artificial Intelligence Risk Assessment

  Distinguish between short-term traffic shocks and long-term changes in industry structure

  The Middle East conflict and high oil prices are viewed as near-term capacity risks; the impact of artificial intelligence on GDS is seen as a longer-term risk, while its direct threat to Airline IT is considered low.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Amadeus IT Group, SA (AMS.SM)

  Core bullish name

  Strengths

  Leading market share in airline distribution and Airline IT; Airline IT and hospitality businesses contribute more than 60% of EBITDA; continued investment of about 20% of revenue in R&D; new Altéa and Altéa NDC contracts, Nevio opportunities, a healthy balance sheet, and cash returns support growth.

  Weaknesses

  High exposure to Middle East traffic, long-term lack of growth in the mature GDS business, and near-term bookings and airline distribution guidance affected by capacity cuts.

  Comparison

  Compared with Sabre, its business mix is more tilted toward structurally growing Airline IT and Hospitality IT, with stronger product investment, market position, and financial resilience.

  Risks

  Further capacity cuts caused by conflict or oil prices, long-term weakening of GDS, customer migrations falling short of expectations, AI concerns continuing to weigh on valuation, and errors in judging the identity of new contracts.

• Sabre Corp (SABR)

  Neutral allocation name

  Strengths

  Exposure to North America and corporate travel is relatively defensive in the current environment; second-quarter bookings and boarded passengers grew; recent commercial progress improved near-term earnings forecasts; debt maturities are limited before 2029.

  Weaknesses

  About 80% of revenue depends on the low-growth GDS market; the IT business is concentrated among a few large customers; revenue per boarded passenger is declining; net leverage is expected to remain above 5x into the early 2030s.

  Comparison

  Near-term transaction volumes are better than Amadeus', but long-term growth quality, business diversification, product competitiveness, and balance sheet are all weaker.

  Risks

  Large PSS customers such as Lion Air may migrate away, customer concentration risks such as American, an airline-cycle downturn, deterioration in long-term GDS economics, slow deleveraging, and high leverage amplifying earnings volatility.

Key data

• Airline traffic growth in the second half of 2026About 2%Still below normal levels, affected by traveler caution and rising fuel costs.
• Global airline seat capacitySecond quarter -1%; third-quarter schedules +2.6%; fourth-quarter schedules +1.5%Fourth-quarter visibility is lower, and schedules may still be revised downward if fuel prices remain elevated.
• Recovery levels of major Middle Eastern airlinesEmirates 98%; Etihad 98%; Qatar about 100%All relative to normal operating levels before the conflict, indicating regional traffic is recovering.
• Amadeus second-quarter bookingsDown about 7.6% to 8% year on yearMainly affected by Middle East exposure and airline capacity cuts.
• Amadeus second-quarter boarded passengersDown 0.6% year on yearThe Middle East and Africa fell 8%, while North America fell 16% due to Spirit's exit.
• Amadeus revenue per boarded passengerUp 6% year on year at constant currencyDriven by value-added sales, Nevio revenue, and airline professional services.

• Sabre revenue per boarded passengerDown 6% year on yearThe decline in unit revenue turned revenue growth negative again.
• Amadeus new Altéa contractMore than 40 million annual boarded passengers, expected migration in 2027Bernstein speculates the customer may be Lion Air and estimates its 2025 boarded passengers at 50 million to 60 million, but this identity has not been confirmed.
• Basis for Amadeus target price€78, corresponding to 19.7x 2027 EPS of €3.97The target price was raised from €75, with the rating maintained at Outperform.
• Amadeus medium-term total shareholder returnAbout 15% per year from 2027 to 2030Assuming valuation multiples remain unchanged, returns come from net profit growth, dividends, and share buybacks.
• Sabre valuation and leverageTarget price $1.75; 6.7x next-year EV/EBITDA; net leverage expected to remain above 5x for the long termDebt maturity pressure is limited before 2029, but organic deleveraging is slow.

Impact & implications

Airline capacity reductions will first affect airline technology companies that depend on transaction volumes, while airlines can pass on part of the cost through higher fares; therefore, strong fares do not necessarily equate to strong traffic for airline technology suppliers. Amadeus' distribution business remains under pressure in the near term, but Airline IT unit revenue, contract wins, and cost improvements provide an earnings buffer, and its valuation may also benefit from the market's reassessment of AI risk. Sabre's near-term traffic is relatively resilient, but its business structure is tilted toward the mature GDS market, and potential major customer losses and high leverage make its long-term risk-reward inferior to Amadeus.

Risks

• A renewed escalation of the Middle East conflict or persistently high fuel prices could prompt airlines to further cut winter capacity.
• Visibility into fourth-quarter airline schedules is low, and current capacity growth plans may be reduced before actual flights are operated.
• Artificial intelligence and airline direct-connect channels may reduce GDS share of global bookings and bargaining power over the long term.
• Amadeus' identification of the new Altéa customer as Lion Air is only analyst speculation, and the actual customer or migration timing may differ.
• If Sabre loses major PSS customers, its customer concentration, high leverage, and slow deleveraging could amplify the financial impact.
• The airline industry is cyclical, and future demand weakness could simultaneously depress bookings, boarded passengers, and supplier earnings.
• Company forecasts depend on airlines completing system migrations, value-added module sales, and structural cost reductions as planned.

What to watch

• Whether airline capacity continues to be revised downward in the fourth quarter of 2026 and the first quarter of 2027.
• Aviation fuel prices and airlines' ability to pass costs on through fares.
• Whether Middle Eastern airlines such as Emirates, Qatar, and Etihad can continue to maintain operating levels close to pre-conflict levels.
• Amadeus' delivery against its reduced airline distribution revenue and EPS guidance.
• Whether the identity, migration timing, and contract size of the new Altéa customer with more than 40 million annual boarded passengers are confirmed.
• Whether British Airways' adoption of Altéa NDC brings more airline and travel management company contracts.
• Nevio tendering and signing progress in the United States, Asia, and the Middle East.
• Trends in bookings, boarded passengers, and unit revenue for Amadeus and Sabre.
• Whether AI booking capabilities, airline interface development, and corporate travel channels achieve substantive commercial implementation.
• Sabre's net debt-to-EBITDA ratio, free cash flow, and refinancing arrangements around 2029.
