Booking Through CNX 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 CNX, using CNX as the destination:

Amadeus:  AN15JULLHRCNX

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
LHR (London)9,015 km / 5,602 mi≈ 10.6h nonstop
JFK (New York)13,367 km / 8,306 mi≈ 15.7h nonstop

SIN (Singapore)2,011 km / 1,250 mi≈ 2.4h nonstop
SYD (Sydney)8,055 km / 5,005 mi≈ 9.5h 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 CNX
