Waitlist vs standby processing
I'm on the waitlist (cash ticket, not award) for SQ21 in a few days (EWR-SIN). Have a confirmed ticket via NRT out of JFK a few hours later in case it doesn't clear. Is it worth going out to EWR on the morning of and seeing if it clears on the day? How does SQ process waitlist vs standby? Appreciate any insights / advice.
(I did search on this but everything I could find is about award waitlists rather than cash fares!)
