B4 (B4)

20 non-stop routes across 10 airports. Main hub: Dubai (DWC).

About B4

B4 is a commercial airline built around a Dubai World Central (DWC) hub, which already tells you something about its positioning — DWC is Al Maktoum International, the newer Dubai airport, not the chaos of DXB. With 20 non-stop routes spanning 86,420 km of total network and 10 airports across four continents, this is a focused operator rather than a sprawling global carrier. The route map skews heavily toward leisure and high-demand corridors: UAE, Saudi Arabia, the Maldives, Italy, and the UK. That's a deliberately curated network, not random growth.

Why fly B4?

The honest case for B4 comes down to where it flies, not how many places it reaches. Seven routes out of DWC means real frequency and operational focus at that hub — this isn't a carrier spreading itself thin. The LHR-DWC route at 5,513 km is the crown jewel, connecting London Heathrow directly to Dubai's secondary airport, which often means less ground congestion than DXB. If you're routing through to the Maldives, B4's MLE hub with three routes gives you options that most carriers don't bother building. The Saudi Arabia coverage — three routes — is genuinely useful for business travelers who know how hard those seats can be to find at reasonable prices.

Tips for booking B4

Book DWC-originating routes first — seven routes concentrate the airline's best operational reliability here, so connections and rebooking options are stronger than at thinner hubs like RSI. If you're targeting RSI (Red Sea Project) with only two routes served, treat it as a point-to-point trip rather than a connection hub. MXP gives you Milan Malpensa access on two routes, which is typically cheaper than flying into Linate. The LHR route is worth checking even if you're not London-based — positioning to Heathrow on a budget carrier then picking up B4 long-haul can save serious money compared to one-carrier itineraries.
