About BI
Royal Brunei Airlines — operating under the IATA code BI — is the national carrier of Brunei Darussalam, a small but extraordinarily wealthy sultanate on the island of Borneo. It's a legacy airline in the truest sense: state-backed, flag-bearing, and oriented around connecting its tiny home nation to the wider world rather than chasing volume. With 46 non-stop routes spread across 23 airports, BI punches well above its weight geographically, threading together a network that stretches from Southeast Asia to the Middle East and deep into Europe.
Why fly BI?
The most compelling reason to consider BI is the LHR-BWN route — at 11,282 kilometres, it's the airline's longest, and it offers something increasingly rare: a long-haul flight that doesn't feel like a cattle run. Royal Brunei has built a reputation for attentive, unhurried service that reflects the country's own quietly gracious culture. If you're routing through Southeast Asia — particularly into Indonesia, Malaysia, or China, where BI holds three routes each — BWN works surprisingly well as a connecting hub. It's a small airport, which means you're not sprinting between terminals. The airline's alcohol-free policy is worth knowing upfront; it's not for everyone, but many travellers find the atmosphere noticeably calmer for it.

Tips for booking BI
First-timers should know that BWN is the heart of everything here — 22 of BI's 46 routes originate there, so your connection options depend heavily on how well your inbound timing aligns with onward departures. The Brunei airport is compact and manageable, but connection windows can be tight, so don't book the minimum. BI also operates out of LHR and DXB with a handful of routes each, which gives European and Gulf-based travellers a useful entry point. Check fare classes carefully before booking — promotional fares sometimes carry restrictions that full-service passengers don't expect from a legacy carrier.
