I reckon it will be tomorrow but that means it will probably miss the post in the morning. So will probably be sent out the next day and arrive sometime Saturday. So impossible to book a new flight with that level of uncertainty.
It honestly doesn’t make sense though as they approved Conz1234 at 2.30pm and sent it to print at 3pm – that was a full 15 -16 hours after mine was approved.
My advice would be to fast track your passport in any way you can Sunshine. This has been a horrific fortnight.
