Thank you so much for this reply – I really appreciate the detail and time spent for you to write this!
We don’t fly until the 25th June but our passports were stolen at a rather inconvenient time so after 2 days of no sleep and a failed attempt at booking a fast track appointment (where they took the £300 but didn’t give me an appointment!) I gave up and applied on the 5th and are just hoping for the best!
Hopefully it doesn’t come does to the upgrade service but at least I know there’s options if it doesn’t arrive!
