Ninety-plus airlines fly into DXB, so the flight itself is never the hard part; the arithmetic afterwards is. Terminal 3 is Emirates' private cathedral of duty-free, but budget an extra 30-45 minutes for immigration if you land in high season. Tabby, Tamara, Postpay and Klarna all sit at checkout, which matters when a mid-range day here runs USD 90 or more. London's seven-hour hop averages USD 480, Mumbai's quick three-hour dash a mere USD 180, proof that Dubai's guest list is genuinely global.
