Hi Peter,
I can't see a reason why this isn't showing. I know it's a daft question, but I thought I would ask - have you tried 'linking' your booking to your account. On the 'Your Holiday' tab, if you put in the booking reference, departure date and your postcode, this should pull through the booking into your account. can you let me know, and if it still isn't showing, I'll get our IT team to take a look.
Kindest regards,
Julia
