A video circulating on Facebook since June 3 shows a group of passengers decked out in blue personal protective equipment milling about an area that looks like one of the boarding gates at Changi Airport.

This scene was most likely the return of Vietnamese back home.

The passengers were preparing to leave Singapore while taking enhanced measures in the midst of the Covid-19 pandemic that has not completely subsided here.

Vietnam has seen 544 of its citizens in total sent back on two flights from Singapore on April 24 and May 31.

A photo released by Vietnam Airlines on the second flight out of Singapore showed rows upon rows of passengers wearing blue PPE on the plane as they returned home.

Those on board included pregnant women, the elderly, youth under 18, people suffering illnesses, and workers or tourists whose visas had expired, according to a Vietnam Foreign Ministry release.

They paid their own fares.

A few clues in the video hints at where it was shot.

The carpet and orange and black seats are furnishings seen at Changi Airport Terminal 3.

The Changi Airport airline information also lists Vietnam Airlines as operating out of Terminal 3.
