MH603 route overview: KUL to SIN

MH603 distance and great-circle path

MH603 covers 296 km, or 184 miles. That makes it a short-haul flight, a single-aisle hop where turnaround time matters more than range. Of the 255 routes we track, it ranks 255 by distance.

The plane leaves Kuala Lumpur heading south-east. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the KUL–SIN route appears on a tracker map.

Why MH603 block time differs from cruise time

The schedule allows 1.1 hours from gate to gate. That works out to about 274 km/h. A Boeing 737-800 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying east, this route usually picks up tailwinds high up. The flight back west normally takes longer, even though the distance is identical. See what really moves flight times.

Can the Boeing 737-800 comfortably fly MH603?

Not at all. At roughly 5% of its range, this is an easy trip for a Boeing 737-800. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 737-800.

What to know about MH603

  • Time change: none. Both cities keep the same clock, so arrival time reads exactly as you expect.

MH603 against the rest of the KUL-SIN pairing

We track 2 scheduled services between Kuala Lumpur and Singapore, split between AirAsia and Malaysia Airlines. Among them, it is the first departure of the day on this route; it is scheduled quicker than anything else on the pairing; it is the only one flown with a Boeing 737-800.

Measured against MH603, which pushes back at 07:20:

  • AK720 (AirAsia) leaves 40 minutes later and is given the same block time, on an Airbus A320.

Block time is gate to gate, so it counts taxi at both ends. That is why two flights covering identical distance rarely share a scheduled duration.
