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

Swap in the actual origin code and date for a live search — the structure (date, then city pair) stays the same across systems.
Real, calculated straight-line distances (great-circle) and a rough nonstop flight-time estimate:
| Hub | Distance | Est. Flight Time |
|---|---|---|
LHR (London) | 2,488 km / 1,546 mi | ≈ 2.9h nonstop |
JFK (New York) | 8,027 km / 4,988 mi | ≈ 9.4h nonstop |
DXB (Dubai) | 3,028 km / 1,882 mi | ≈ 3.6h nonstop |
SIN (Singapore) | 8,678 km / 5,392 mi | ≈ 10.2h nonstop |
SYD (Sydney) | 14,971 km / 9,303 mi | ≈ 17.6h 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.
London is the closest of the listed hubs to IST, at roughly 2.9 hours nonstop, while Sydney is the furthest, at roughly 17.6 hours. When an itinerary routes a client through IST as a connection point rather than a final destination, it's worth confirming minimum connection time directly with the airport or airline — this varies by terminal and by whether the connection involves a change of airline alliance.
