There's more than one way to fly between Sydney and Bangkok in business class, with Qantas, Thai Airways and even Emirates jetting between the two cities.
Depending on which airline and flight you book, you could end up in a fully-flat bed with an inflight cocktail bar at your disposal, or in an angled-flat business class seat aside a noisy galley.
Australian Business Traveller examines your options on this popular international route based on the full experience you'll have from door to door as a business class passenger, while also including the price you'll pay to take a return trip in mid-February 2017.
1. Emirates Airbus A380
Emirates covers an expansive network of Australian routes with passengers able to fly the Airbus A380 solely between Sydney and Bangkok – you don't need to be travelling onwards to Dubai or elsewhere to book this flight.
Upsides: Fully-flat beds and direct aisle access come standard in Emirates' A380 business class...
... but so does an inflight bar and lounge area where you can socialise with fellow travellers while enjoying a cocktail at 40,000 feet.
Free inflight Internet is too provided with 10MB of data offered at no charge and a further 500MB available for only US$1, while Emirates' lounge in Bangkok also adopts the airline's latest design palate, as also seen in Melbourne, Perth and Los Angeles.
But wait, there's more – Emirates business class passengers enjoy complimentary chauffeur-driven airport transfers at each end of their journey, while Qantas Frequent Flyer members can earn both points and status credits on these flights by booking them under a Qantas (QF) codeshare flight number.
Downsides: Those chauffeured rides are only available when booked on an Emirates (EK) flight number, not a Qantas (QF) flight number, so if your goal is to earn Qantas Points, you'll need to choose between Chauffeur Drive and earning status credits: you can't have both.
Emirates' lounge in Sydney is also a step behind that found in Bangkok, but remains leagues ahead of the nearby Qantas business class lounge.
Schedule: Emirates offers a return daily service with EK419 (QF8419) leaving Sydney at 7:50pm, reaching Bangkok at 1:10am early the next day. Homeward-bound, EK418 (QF8418) pushes back at 7:30pm, landing in Sydney at 9am the following morning.
Price: From $3,349 return in mid-February

2. Qantas Airbus A330
Upsides: Also promising direct aisle access from every seat in a 1-2-1 layout, Qantas' Airbus A330 Business Suites offer plenty of storage that's useful on both daytime and night-time flights, including for gadgets of all sizes, reading material, glasses and more.
The seat can also remain partially reclined for take-off and landing and lie fully-flat in between – provided you don't immediately drift off to sleep!
During waking hours, ensure you get your first meal choice on flights from Australia by pre-ordering your preferred main course via the 'manage by booking' section on the Qantas website. Platinum frequent flyers are also treated to the superb Qantas First Lounge in Sydney when beginning the journey.
Downsides: There's no ideal pair of seats for couples travelling together or colleagues and friends hoping to chat, with even the middle pairs having a fixed privacy divider in between that can't be opened or moved.
However, savvy Qantas business class travellers can instead visit the modern Cathay Pacific and Emirates lounges in Bangkok for a better pre-flight experience, courtesy of Qantas' Oneworld and Emirates partnerships.
Schedule: Qantas flies daily in each direction with QF23 departing Sydney at 9:45am to arrive in Bangkok at 3:35pm. On the return, QF24 is wheels-up at 6pm for a 7:25am landing in Sydney the following morning.
Price: From $3,349 return in mid-February

3. Thai Airways Boeing 747
Thai Airways offers the most flights between Sydney and Bangkok of any one airline, although the business class seats it flies to Sydney don't come close to rivalling those of Qantas or Emirates.
Upsides: Thai's biggest drawcard is its schedule, with a daily return flight complemented by four additional return services each week to provide added flexibility for business travellers.
Business class passengers can also down a fresh barista-made coffee at the Air New Zealand Sydney lounge before leaving Australia...
... and in Bangkok, can head to the Thai Airways Royal Orchid Spa for a complimentary 30-minute foot massage or neck & shoulder massage before their flight, with treatments secured on a first-come, first-served basis.
On flights from Bangkok, you can also lock-in your preferred meal choice from the standard inflight menu plus a broader selection of dishes available exclusively to those who pre-order online: similar to Singapore Airlines' Book The Cook service.
Downsides: Thai Airways' Boeing 747 business class beds don't lie fully-flat, nor do they provide direct aisle access from every seat. Instead, you'll find them in a 2-2 layout, both on the jumbo's upper deck and also downstairs, with some seats bordering a galley rather than windows.
The Air NZ lounge Thai uses in Sydney can also be quite busy in the mornings, while in Bangkok, we'd consider Thai's array of Royal Silk business class lounges to be more 'acceptable' than 'amazing'.
Schedule: Thai's daily TG476 flight from Sydney takes the skies at 10am to reach Bangkok at 3:35pm the same afternoon, with TG475 jetting to back Australia at 5:50pm local time, arriving at 7:10am the following morning.
Additionally, TG472 flies from Sydney on Mondays, Wednesdays, Fridays and Sundays at 4:10pm ahead of a 9:35pm arrival in Bangkok, with TG471 taking wing at 7:25am on Tuesdays, Thursdays, Saturdays and Sundays in reverse, reaching Sydney at 8:45pm the same calendar day.
Price: From $3,340 return in mid-February
