Distance & Flight Time from Other Major Hubs

Real, calculated straight-line distances (great-circle) and a rough nonstop flight-time estimate:

HubDistanceEst. Flight Time
LHR (London)10,881 km / 6,761 mi≈ 12.8h nonstop
JFK (New York)15,339 km / 9,531 mi≈ 18.0h nonstop
DXB (Dubai)5,845 km / 3,632 mi≈ 6.9h nonstop
SYD (Sydney)6,294 km / 3,911 mi≈ 7.4h nonstop

Flight time is a rough estimate based on typical long-haul cruise speed — actual routing, wind, and aircraft type will change the real duration.
