I had the text from passport office that it was despatched Thursday , but no tracking is working yet .
i am hoping looking at your timelines mine should appear on TNT today , as i fly Friday
From what I can gather and from personal experience the printed update on the application tracking is triggered when TNT collect the document. You do know you can use your PEX number and postcode to track it on the TNT site – just enter your PEX number in Application reference on the tracking page
