There is a big holdup at Changi Airport Terminal 1 Immigration,
says STOMPer V, in an email to STOMP at about
11.20am today (Dec 16). Many passengers are missing their flights,
as a result of what seems to be a computer system breakdown.
Said the STOMPer:
"Big jam at T1 immigration. Computer system down. People are
missing flights."
