Kuwait International posted its busiest year ever in 2025 — 15.7 million passengers — with Jazeera Airways edging past the flag carrier at its own home airport, as Foster + Partners' trefoil Terminal 2 rises toward a 25-million capacity.
Kuwait International ended 2025 at 15.7 million passengers — 7.78 million of them departing — the busiest year in its history, and a market only 1.8% above its 2019 size. The structural story is unique in the Gulf: Jazeera Airways handled 4.77 million passenger movements to Kuwait Airways' 4.70 million — 30.3% of the airport against 29.9% — making KWI the only Gulf hub where a low-cost carrier outsells the flag carrier. No foreign airline reaches 4%; Qatar Airways leads that pack at 3.7%.
The geography is split three ways. Terminal 1 carries the foreign airlines; Terminal 4 is Kuwait Airways' own house; Terminal 5 belongs to Jazeera — a private terminal with 22 check-in counters, centralized security and a ten-minute kerb-to-gate promise, plus early check-in at the Park & Fly from 36 to 6 hours before departure. The flag carrier, launch operator of the Airbus A330-800neo, fields around 32 aircraft; Jazeera doubled its share in six years.
Terminal 2 is the reason this airport's story is about to change: Foster + Partners' three-winged trefoil, 750,000 square meters under one solar-harvesting roof with a sand- and blast-resistant facade, designed for 25 million passengers a year — 50 million with further build-out — and gates for 21 A380s plus nine narrowbodies. When it opens, the scattered terminals consolidate into a single hub statement for Vision 2035.
The system proved its resilience the hard way: after Kuwait's airspace closed on 28 February 2026, commercial operations stopped for 56 days and restarted on 26 April — with Terminal 5 back to full service within weeks and the two carriers dead-heated at 30.6% each through the year's first eight weeks. For visitors: nationals of 53 countries get a visa on arrival or e-visa (KWD 3, up to 90 days), GCC residents of any nationality since August 2025; the airport sits 16 km south of the center, with 24-hour CityBus airport expresses X1–X4 and taxis at roughly KD 15 to town.
Our read: Kuwait International is the Gulf's most idiosyncratic hub — the only one where the discounter outsells the flag carrier and owns its terminal. Fly Jazeera and T5 gets you from kerb to gate in ten minutes, with bags checked the night before at Park & Fly; fly Kuwait Airways and Terminal 4 is calm by Gulf standards. Check your terminal twice — T1, T4 and T5 are separate buildings with separate drop-offs, and a wrong one costs you a drive around the airfield. Until the trefoil opens, that is the one mistake this airport still lets you make.
