Question: What should I do if I have COVID-19 symptoms while on an international flight?

Answer passage (source: Australia):
page_title: Industry and employers
section_headers: Airline industry
section_content: From 2100 AEDT 20 March 2020, airline staff should ensure that only exempt
travellers board a flight to Australia. Where possible, the Australian
Advanced Passenger Processing system will be used to deny uplift for all other
travellers.
The Australian Government will honour all “okay to board” messages that
airlines receive.
Airlines must contact the Australian Border Force Border Operations Centre
prior to non-exempt travellers boarding the flight.
Airline crew (including medivac crew) are exempt from the travel restrictions.
Airline crew are advised to take particular care on lay-overs, to use
dedicated private transport and to avoid crowded public spaces.
Airline crew should monitor for symptoms and not fly if they are ill. This
includes off-shift crew who are travelling as passengers on an aircraft to
reposition at another location. The same process is to be followed for this
cohort as on-shift crew.
Airline crew are required to self-isolate in their accommodation, if they
enter Australia, until their next work flight.

Reviewer feedback on this answer:
It talks more about what the airlines should do instead of the person. It's directed at airlines staff.
This does not answer the question. This information is intended for airline staff and airline crew during Covid-19 pandemic and does not provide any information on what people should do if they start showing Covid-19 symptoms while on an international flight.

No flights out?
section_content: If you wish to return to Australia, and there are still commercial flights
available, take them as soon as possible. While we know it can be frustrating
or expensive, the window of opportunity is closing.
Many travellers are having difficulty getting home because of flight cancellations or movement restrictions.
If you’re one of them, we know it’s a stressful and difficult time.
Where commercial flights are not available, we’re working with the airline
industry and other governments to help Australians find ways to get home. This
includes a special partnership with Qantas and Virgin Australia and
facilitated flights from several destinations.
See further details on the COVID-19 – Helping Australians to return
home page.
Over the past few weeks, we’ve also worked with cruise operators and other
governments to bring home thousands of Australian passengers from cruise
ships.
Check the website of your nearest Australian embassy or high
commission and follow them closely on social
media for updates
about flights back to Australia. Some embassies and high commissions are
providing the option for Australians to register for direct communication,
including in some places to receive updates on potential unscheduled
commercial flights.

Reviewer feedback on this answer:
The response is about getting back to Australia. It doesn't mention being sick on a plane.
This answer is irrelevant to the question. The question is asking for information on what people should do should they develop Covid-19 symptoms during an international flight. And this answer is providing information on how Australians can return to Australia during the Covid-19 pandemic when flights are being cancelled and movement restricted.
