Gorcat;
I can tell you that my flight was supposed to leave yesterday from JFK to Frankfurt it was canceled in mid May. On the app I show all the information, even noting that the fight had actually landed. But the flight never happened.
it also shows my return flight on 16 June. Even though that flight is canceled.
but I noticed that under my name it says ‘not ticketed‘. That’s really the only indication.
when I called Singapore airlines they confirmed that the flight has been canceled and that my request for refund had been submitted three weeks earlier.
so I think the app does not reflect the fact that the flight is canceled.
Maybe call SingaporeAir early some morning and just verify that there is a refund request in the system. It gave me peace of mind.
