(22 Feb 2026, 11:31 am)PH - BQA wrote 1499 is consistently allocated to the 553 otherwise (bar the periods mentioned above), and has been since they started running the 553 with it. I'd say it is extremely unlikely that one person being on holiday resulted in a full week of it being allocated elsewhere, largely because I believe it is a rota and the same person does not do allocations for a full week regardless.
Not recently it hasn't mind; it's been a bit random since the start of the year really; it only done Thurs and Friday the week before for example.
and wasn't on the 9th/12th/13th/16th/19th/20th January either, the vehicles you mentioning above being on the other weeks.
