Booking Through LHR Across GDS Systems

The same availability check looks different depending on the GDS in front of you. Here's the pattern for a generic search into LHR, using LHR as the destination:

Amadeus:  AN15JULLHRLHR

Swap in the actual origin code and date for a live search — the structure (date, then city pair) stays the same across systems.

Distance & Flight Time from Other Major Hubs

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

HubDistanceEst. Flight Time
JFK (New York)5,540 km / 3,442 mi≈ 6.5h nonstop
DXB (Dubai)5,497 km / 3,416 mi≈ 6.5h nonstop
SIN (Singapore)10,881 km / 6,761 mi≈ 12.8h nonstop
SYD (Sydney)17,020 km / 10,575 mi≈ 20.0h 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.

Connection Notes for LHR
