Summer holidays: Why travellers are swapping the Riviera for the Balkans

Croatia's Adriatic region logged 34 million nights booked across Airbnb, Booking and Expedia between June and Sept 2025, making it the EU's top regional summer destination. At the country level France led with 108M summer nights, Spain 91M and Italy 75M; total online short-stay nights in 2025 were ~950M (+11.4% vs 2024, +32.4% vs 2023). The data signal healthy demand for travel and hospitality exposures, but a war-driven spike in oil/jet-fuel costs could force airlines to trim capacity and raise fares in 2026, creating downside risk for airlines and price-sensitive tourism flows.

Analysis

Platform economics are the hidden lever here: when destination capacity tightens (local permits, ferry slots, boutique hotels) platforms can capture much of the price upside because distribution stays concentrated while supply is inelastic. BKNG’s scale and ad/merchant mix gives it structural pricing power in higher-yield, short-lead urban and packaged bookings, whereas ABNB’s inventory elasticity and longer-stay skew make it the more durable beneficiary of dispersed ‘overflow’ tourism into secondary towns and islands.

The principal risk is a supply-side shock to airlift rather than demand destruction: sustained jet-fuel shocks (weeks–months) will induce capacity cuts and higher fares that redistribute flows from long-haul to short-/drive-reachable markets and accelerate cancellations for marginal trips. Local regulatory interventions (caps, tourist taxes, stricter short-term rental rules) are asymmetric catalysts — they reduce nights but raise ADR and platform take rates, so a headline dip in nights can coincide with revenue per night rising for platforms.

From a timing perspective, monitor fuel-cost moves and airline capacity notices over the next 30–90 days as the earliest catalyst; structural modernization of regional transport (ports, small airports) and regulatory shifts will play out over 6–24 months and determine whether supply tightness is transitory or persistent. The consensus is too binary: it assumes bookings=revenues; the second-order win is monetization per booking, which favors the largest, ad-rich OTAs and scalable marketplace platforms even if nights normalize.

Key Decisions for Investors

• Long BKNG vs Short EXPE pair (equal-dollar, 6 months): alloc 1.5% NAV long BKNG / 1.5% NAV short EXPE to capture BKNG’s superior ad/merchant leverage if fuel-driven fare increases compress EXPE’s margin-heavy segments. Target 20–30% relative return; stop 12% adverse divergence.
• Directional call-spread on BKNG (3–6 months): buy a 3-month ATM call / sell a 20% OTM call to fund it (debit spread) sized at 0.5% NAV — asymmetric upside if summer-booking monetization holds while limiting premium paid. Reward ≈ 2–4x premium vs max loss = premium.
• Long-dated ABNB call calendar (buy Jan-2027 10% OTM calls, sell Oct-2026 ATM calls, small net debit): 1% NAV to play durable reallocation to home-sharing in secondary coastal towns and islands as travelers avoid crowds; time horizon 6–12+ months. Expect moderate upside with theta cushion vs outright calls.
• Defined-risk put spread on EXPE (6 months): buy 25% OTM put / sell 40% OTM put sized at 0.75% NAV — hedge against demand/airline-capacity shock that disproportionately hurts EXPE’s cost structure. Potential payoff 3–4x premium if bookings fall; max loss = premium paid.
• Trigger monitor & hedge: if jet-fuel/Brent proxy rises >15% in 30 days, reduce net-long exposure to OTAs by 25% and rotate into ABNB over EXPE (short-term flight-sensitivity hedge).
