CATHAY PACIFIC: Adelaide to Hong Kong flights return for summer

Cathay Pacific will return to Adelaide for another Southern Hemisphere summer season, this time offering up to five weekly non-stop flights to Hong Kong during the busiest holiday months.

The service will operate from 10 November 2026 until 27 March 2027. There will be three flights each week during November and March, increasing to five weekly services from December through February.

Three flights a week seemed like dipping a cautious toe back into the market. Five flights resembles a regular airline service.

More flights over the summer peak

Cathay has been absent from Adelaide for more than five years. The airline had served the city since 1992, but suspended the route in March 2020 due to the pandemic.

That timing is clearly aimed at Christmas, New Year, school-holiday and Lunar New Year traffic. It also gives South Australians considerably more flexibility when connecting through Hong Kong rather than building an itinerary via an Eastern States capital like Melbourne or Sydney.

Adelaide–Hong Kong timetable

The flights will operate as follows, with all times local:

Flight	Route	Departure	Arrival
CX174	Adelaide–Hong Kong	12:00	18:15
CX173	Hong Kong–Adelaide	23:30	10:30 the following day

Cathay lists the Adelaide–Hong Kong journey at around eight hours and 15 minutes, while the southbound flight takes a little over eight-and-a-half hours.

The midday Adelaide departure is civilised and reaches Hong Kong early enough for some evening connections. Some passengers heading further afield may face a longer transit. The return flight is an overnight service.

Cathay’s Airbus A350 returns

Cathay will use its Airbus A350 on the route. The airline’s 280-seat A350-900 carries 38 flat Business Class seats, 28 Premium Economy recliners and 214 Economy seats.

Business Class uses Cathay’s established fully-flat product rather than the newer Aria Suite being rolled out on refurbished Boeing 777s. It lacks a sliding door, but remains a comfortable and private long-haul seat.

Premium Economy is an especially welcome inclusion. Before the route’s post-pandemic return, Cathay had not offered the cabin on its Adelaide services. It provides a considerably more cost-tolerable option for an eight-hour flight, but note that many regard it as Economy plus rather than Business lite.

Complimentary WiFi is available to passengers in Business and Premium Economy, as well as Cathay Gold and Diamond members. Qantas status holders do not receive free connectivity. Eligible Cathay fares can earn Qantas Points and Status Credits.

Another useful route into Asia and Europe

Hong Kong provides South Australians with direct access to one of Asia’s major aviation hubs and connections across mainland China, Japan, Korea, South-East Asia, Europe and North America.

It also gives Adelaide travellers another alternative to Singapore Airlines, Malaysia Airlines, China Southern, Emirates and Qatar Airways. Competition is particularly valuable during the Christmas peak, when international fares can rapidly move from merely expensive to the point of contemplating a second mortgage.

The route also has a substantial freight role. When Cathay first announced its Adelaide return, the South Australian Government estimated the passenger and freight service could generate around $32 million annually for the state, with wine, seafood and technology products among the likely exports.

Seasonal remains the important word

The extra flights are good news, but Cathay’s Adelaide service remains seasonal. The aircraft disappear again after 27 March 2027, leaving South Australians without a direct Hong Kong flight through the Australian winter.

The obvious next step is a year-round service. Daily flights would be even better, but five weekly services over summer should first give Cathay a clearer picture of whether Adelaide can support something more permanent.

This is great news for Adelaidians. It’s also good news for other Australians, since there are sometimes good deals from Adelaide to Hong Kong and beyond when local demand doesn’t fill the aircraft.

Also, keep looking up those Classic Reward airfares on the Qantas finder website, or direct with Cathay. Despite the devaluation of conversions (for example, Amex went from 2 points to 3 points to one Cathay point recently), there is good availability of points redemption flights on Cathay, especially on hard-to-get routes like to Europe.

I’m travelling on an Amex/Cathay Pacific points-redemption ticket to London later this year.
