Hong Kong Airlines is reported to be stepping up Hong Kong–Sydney from four-weekly to daily from 1 December, and the first aircraft in its new 20th-anniversary livery has just made its first long-haul appearance in Sydney — after first returning to Hong Kong and flying a Shanghai rotation. There is also an official anniversary fare sale from Hong Kong, open through 30 November.

The reported daily uplift
Current pattern: four-weekly Hong Kong–Sydney
Reported change: daily from 1 December 2026
Karryon, quoting Huang Pingtao (GM Sales and Marketing Australia): daily between 1 December 2026 and 28 March 2027
TravelTalk (29 September 2026): HX017, Hong Kong 22:25–Sydney 11:05+1; HX018, Sydney 12:35–Hong Kong 19:35; last outbound 27 March, last return 28 March
That is trade reporting — Huang on the record to Karryon, and an earlier TravelTalk schedule listing — not a Hong Kong Airlines corporate announcement. Confirm the live times in the booking engine before you rely on a published 22:25 or 12:35.
The Blossom at Hong Kong, then Sydney
The new look is officially called The Blossom, built around the bauhinia. The airline announced it in May as the first tail-livery update since it was founded, with four aircraft due to be repainted during 2026. The first aircraft is Airbus A330 B-LHJ. Official Weibo posts on 6 November showed it back at Hong Kong — “首架采用全新喷涂设计的飞机(B-LHJ)正式归队” — and on 8 November listed it on Hong Kong–Shanghai Hongqiao, HX238/HX239.
Sydney, on 9 November, was the first long-haul and Australian appearance, not the first time the painted aircraft had flown. Official Weibo posted arrival pictures from Sydney that day, and Huang told Karryon the route was “the first long-haul destination to welcome our new livery.” On 10 November the airline’s Weibo account posted departure shots of HX018, Sydney 12:35–Hong Kong 19:35.

20th Anniversary Celebration (official website sale)
The official consumer offer is Hong Kong Airlines 20th Anniversary Celebration (香港航空二十周年誌慶). It is not titled “Mega Sale”.
Booking period: 4–30 November 2026
Travel period: 10 November 2026–18 March 2027
Direction: selected routes departing from Hong Kong
Discount: up to 20% off the ticket / base fare only — not taxes or surcharges — applied automatically in the search results
Sydney and Melbourne are destinations from Hong Kong on this official table. Economy (classes T, V, W, O) is 15% off one-way and 20% off a round-trip. Business (Z, I) to Sydney or Melbourne is 10% one-way or round-trip, not 20% — the 20% business band is listed for Taipei, Bali, Tokyo and Osaka. Seats, dates and fare rules vary. Book on the official campaign page, the app or WeChat, and check the all-in total before you commit.
If you book through an agent, you may also see a separately described GDS trade sale with different dates and an Australia-origin direction. That is not the official website offer above. Yesterday’s HXciting Tuesday flash has already closed; this anniversary sale runs through 30 November.
The useful bit for Australian summer dates is the reported daily frequency from 1 December, if it holds in the booking engine, plus the official from-Hong Kong discount if your dates sit inside 10 November–18 March 2027. The headline percentage is not the ticket price; confirm the live schedule and fare total on the airline site.
Overall, a reported daily spell on Hong Kong–Sydney through late March, a new The Blossom A330 that reached Sydney only after first coming home to Hong Kong, and an official anniversary sale from Hong Kong if the dates and booking classes line up.
