Flight services at the international airport here will be temporarily suspended for five hours on October 20 to enable the traditional "Arattu" procession of Sree Padmanabhaswamy temple to pass through the runway, TIAL said on Sunday.
The ritual is in line with a decades-old practice involving the Travancore Royals.
The Thiruvananthapuram International Airport Ltd (TIAL), in a statement, said the flight services would be suspended from 4 pm to 9 pm on October 20 to facilitate the 'Alpassi Arattu' procession by the Sree Padmanabhaswamy temple.
It said the updated timings of the flights are available with the respective airlines.
The airport has been pausing operations and rescheduling flights twice every year for decades to enable the bi-annual centuries-old ceremonial procession of the shrine to pass through the runway.
The practice of the temple procession passing through the route to reach the Shangumugham beach for the holy bath of the idols began centuries ago, and it has been continuing even after the establishment of the airport in 1932.
When the airport was constructed in the particular place, the then Travancore King Sree Chithira Thirunal had made it clear that the facility would be open to the public for 363 days in a year and for two days for Lord Padmanabha, the titular deity of the royal family, according to historians.
