Checking in

Singapore Airlines’ Changi operation is, as ever, frictionless. Even at peak periods there’s a sense of calm choreography. With time to spare, the SilverKris lounge offers a pleasant, if somewhat crowded, pre-flight experience.

Baggage

Two checked bags (32 kilograms each), plus a generous cabin baggage allowance of two pieces, up to seven kilograms each.

Loyalty scheme

KrisFlyer members earn miles and status credits, with Star Alliance benefits extending across partner airlines.

The seat

This Singapore Airlines’ A350-900 (medium haul) features a business class cabin of 40 seats in a 1-2-1 layout, with window seats staggered so that some sit flush against the window while others are offset by the storage console.

On the seat map, it’s an impressive proposition: a fully lie-flat bed deployed on routes of four hours or more. And on an evening departure like this one, that promise is enticing. The ability to stretch out, put your feet up and attempt some proper rest could transform what might otherwise feel like a long regional flight.

In practice, however, the execution is less convincing.

At about 20 inches (50.8 centimetres) wide, the seat is noticeably narrower than Singapore Airlines’ long-haul business class, which stretches closer to 28 inches (71 centimetres). The latter is generous by industry standards – but it is a difference you feel immediately.

The seat converts into a fully flat bed of roughly 190 centimetres, but the geometry is awkward.

The sleeping surface angles into a tapered footwell, meaning you lie diagonally rather than straight. Even for a shorter passenger, the space feels constrained. The bed itself is also notably firm. It’s a clever design, but not an entirely comfortable one; the kind of set-up that would benefit enormously from a mattress topper, and you’re not provided with one.

This Singapore Airlines regional business class includes a good pillow and duvet but does not get the full turn-down experience. Amenity kits are provided on request on some but not all flights using this aircraft.

Entertainment + tech

Each seat is equipped with a personal KrisWorld screen, along with Bluetooth audio, USB-A and USB-C charging, and power outlets. The system is responsive and well stocked, though on a flight of this duration and evening take-off, it’s arguably secondary to the sleep potential.

Wi-Fi is available, and the cabin feels modern and well thought out, even if it lacks the sense of space found on Singapore Airlines’ long-haul configurations.

Service

Service remains a standout. Cabin crew strike that familiar Singapore Airlines balance: warm without being overly familiar, attentive without hovering. Even on a relatively short sector, you’re well looked after.

Food

Catering is strong, particularly for a regional route. A multi-course service is offered, with a choice of mains that reflects the destination. Singapore Airlines’ “Book the Cook” service is also available, allowing passengers to preselect dishes. I haven’t done this and opt for the vegetarian Indian main: a warmly spiced curry with rice that feels closer to restaurant cooking than airline catering. It’s comforting without being heavy, thoughtfully balanced, and a reminder of how seriously Singapore Airlines takes its food, even on a relatively short regional route.

Sustainability

Singapore Airlines has partnered with companies such as Neste and World Energy to purchase Sustainable Aviation Fuel (SAF) and SAF certificates, helping to reduce lifecycle carbon emissions from flights. The airline has a long-term goal of achieving net-zero carbon emissions by 2050.

One more thing

This regional business class product will be deployed on Singapore Airlines’ new route from Western Sydney (Nancy-Bird Walton) International Airport from November 23, 2026, taking off at 11.55pm local time, and arriving at 5.05am in Singapore. It operates across a growing number of medium-haul routes, particularly within Asia and on other services to Australia, including Perth, Brisbane and Adelaide.

The price

From about $6700, Sydney to Kolkata return in business standard.**

The verdict

Singapore Airlines’ regional business class delivers a lie-flat bed on routes where it genuinely calls for it. But while the concept is compelling, the comfort isn’t quite there.
