It seems to be a recurring question on the sub re: NJ Transit tickets expiring since there’s been multiple threads in days ^(^1 ^/ 2) , so again: the physical/digital tickets do not expire. The only way they’d expire is if you’d brought one that’s time sensitive, whether it’s a weekly pass, a monthly pass, or a FlexPass (20% discount for 20 one way tickets, valid for a month). If it’s unused, then those (time sensitive tix) are gone for good.
