Swedavia’s traffic statistics for December and all of 2025: Strong demand for both international and domestic travel

Swedavia reported continued recovery in air travel with December passenger volumes up 8% year‑on‑year to about 2.5 million and full‑year 2025 traffic rising 2% vs. 2024. Stockholm Arlanda led growth, with roughly 1.8 million December passengers (+14% y/y), full‑year passenger traffic up just under 7%, international traffic up ~3% and domestic at Arlanda up nearly 29% year‑on‑year; Göteborg Landvetter saw modest gains (~+2% full year). The network expanded with 37 new scheduled routes, eight new airlines and five charter destinations, while freight volumes rose ~5%, signaling strengthening demand toward pre‑2019 international levels and supporting near‑term revenue and capacity planning for airlines and airport operations.

Analysis

Market structure: December +8% YoY (full-year +2%) with Arlanda driving most gains (Arlanda +7% FY, domestic +29% at Arlanda) shifts profits toward airport operators, lessors and premium long-haul carriers serving Stockholm. Winners: airports (stable fee streams, ancillary revenues) and lessors (higher utilization); losers: marginal regional carriers with weak pricing power. Cross-asset: higher jet-fuel demand implies modest upward pressure on crude (positive for energy equities/commodities), and a cyclical uplift that favors cyclicals vs long-duration sovereign bonds.

Risk assessment: Tail risks include pandemic resurgence, strike/regulatory action (airport environmental limits/slot reallocations) and airline credit stress; each could reverse flows within weeks and hit airlines harder than airports. Short-term (days–months): volatility around monthly traffic prints and winter seasonality; medium/long-term (3–24 months): route network durability and macro growth. Hidden dependencies: route additions concentrate at Arlanda (concentration risk) and airline financials determine whether traffic converts to operator profit.

Trade implications: Favor balance-sheet-strong, cash-generative airport operators and lessors over small carriers. Use ETF/lessor exposure for broad capture (lower idiosyncratic risk). Entry: scale into positions now, add on >5% pullback or if two consecutive monthly prints stay ≥+3% YoY; target horizon 6–18 months. Options: use call-spreads to limit premium spend around quarterly prints.

Contrarian angle: Consensus will overweight airlines — missing that airports/lessors monetise traffic more defensibly and benefit from ancillary growth; airline margin squeeze from fuel/competition is underappreciated. Historically (post-2010 recoveries) airports outperformed carriers by 10–25% over 12 months; unintended consequence: capacity growth could depress fares, making airline equities the more fragile lever.

Key Decisions for Investors

• Establish a 2–3% portfolio long in U.S.-listed airline ETF JETS (NYSE:JETS) for 6–12 months to capture broad travel upside; initial stop-loss -12%, add 50% position size if two monthly Swedish traffic prints ≥+3% YoY; target +20–30%.
• Initiate a 1.5–2% long in AerCap (NYSE:AER) as a defensive play on fleet demand and rising utilization (12–24 month view); take profits at +30%, stop-loss -15%.
• Run a 1% pair trade (market neutral notional): long airport operator AENA (BME:AENA / AENA.MC) 1% vs short SAS AB (NASDAQ OMX:SASA.ST) 1% for 6–12 months — close if relative P&L swings >10% adverse to position; rationale: fee-based airport upside vs airline margin risk.
• Buy a 3–6 month call spread on JETS (buy ~20% OTM, sell ~40% OTM) allocating 0.5% portfolio to leverage upside into winter/spring traffic data while capping premium outlay; unwind after two positive monthly prints or at 60% of max spread value.
• Tilt 0.5–1% notional to energy exposure (USO or Brent futures) to hedge higher jet-fuel demand; establish stop-profit at +15% and stop-loss at -10%. Additionally, deploy a 0.5% notional long SEK (short EUR/SEK) if Swedish traffic and PMI prints surprise to the upside in next 60 days; close if EUR/SEK strengthens by 3% against SEK.
