The airline Singapore Airlines intends to operate the Singapore-Munich route again on a daily basis from January 20, 2022. This will bring you back to the level you had before the corona pandemic.
Of the seven weekly trips, five are placed under the so-called Vaccinated Travel Lane program. Specifically, this means that they can only be used by vaccinated people. If all requirements are met, the quarantine in Singapore is not applicable.
The other two rotations are carried out "normally" and can be used by all travelers who are authorized to enter Germany or Singapore.
