Singapore will temporarily freeze flight and bus ticket sales under the Vaccinated Travel Lane (VTL) policy from Dec. 23, 2021, to Jan. 20, 2022, to limit its exposure to imported Omicron cases, said the Ministry of Health in a press release (pdf).
Although VTL ticket sales will resume on Jan. 21, flight and bus ticket sales quotas will be cut by half, according to the Civil Aviation Authority of Singapore and the Ministry of Trade and Industry in two separate press releases.
