Passengers flying from India to Abu Dhabi must isolate on arrival for 12 days and wear a quarantine wristband during this period, Etihad Airways says.
The airline reiterated Covid-19 travel protocols for those flying to the capital from India on its website.
Abu Dhabi's Emergency, Crisis and Disasters Committee updated quarantine measures on July 5.
The travel procedures refer to passengers arriving in the emirate from non-green list countries, such as India.
Vaccinated travellers from green list countries must take a PCR test on arrival and a further test on day six, but are not required to quarantine under the rules set out last month.
The medically-approved wristband will be provided to passengers after they clear immigration at Abu Dhabi Airport.
"When you arrive in Abu Dhabi, you will be required to quarantine for 12 days and wear a medically approved wristband for the duration of your quarantine – this will be provided by the authorities at Abu Dhabi airport after you clear immigration," read guidance on Etihad's website.
"You must also take a PCR test on arrival, day six and day eleven."
Thousands of residents stuck in India after a ban on passenger flights to the UAE was announced in April are trying to get home after flight restrictions were eased last week.
Those returning to the UAE need to have valid residency and proof of having received both doses of a Covid-19 vaccine in the UAE no less than 14 days before travel.
Unvaccinated residents can return if they are school pupils, teachers, university students, lecturers, medical workers, or people who work for federal and local government.
