The Middle East's flagship hub and one of the world's busiest airports for international traffic.
Dubai International is the home base of Emirates and the world's busiest airport for international passenger traffic, handling around 92 million passengers a year across three terminals. Emirates and Qantas codeshare partners use Terminal 3 (the largest single terminal in the world by area); flydubai and most low-cost regional carriers use Terminal 2; older Terminal 1 handles a mix of international airlines.
The airport runs around the clock, there's no night curfew, and is one of the few major airports where the bulk of traffic is genuinely connecting rather than origin-and-destination. Emirates' hub-and-spoke model means many travellers transit DXB without leaving the airport.
For UK travellers parking here, the typical use case is a short business trip, a long-haul leisure stay (one week to a month) where the parking saving over an off-airport lot is meaningful, or expat travel home for several weeks.
