Just an update, today was 48hrs before my flight on Saturday morning and having heard nothing from the Liverpool Upgrade Team, I travelled to Durham passport office this morning. Arrived about 7.15 and was about 10th in the queue. Got seen about 9.45 and by that time there were another 40 or so people behind me waiting to be seen so definitely worth arriving before 8.
The lady I saw was lovely but said because my application was with the Liverpool office and the upgrade request was already submitted, she could only email them to advise I’d attended today and she said they should call me today but basically I was at the mercy of Liverpool!
I left around 10am and drove home but then received a call from Liverpool at 2pm advising the passport was approved and I could collect it from Durham at 4pm.
Drove back and finally got my daughters passport at 5.15 today! Relief! It’s definitely worth travelling to your local office if your 48hrs from flying, I have no doubt that I wouldn’t have had any joy from the upgrade team without Durham contacting them. Good luck all!
