Standing Order with BOI - how long to reach AIB

Hiya
I have set up a Standing Order on a Bank of Ireland a/c. I can see this was taken out of the account on the right day but it does not seem to have hit my AIB a/c yet - can anyone let me know how long this should take?

Thanks

I get paid like so I have a lot of experience!
The official line from BOI is that it takes 3 working days. However, it entirely depends on what day of the week the date falls. E.G. if it's a Friday, it would be common for it to hit AIB the following Wednesday. But I had one recently that left BOI on a Wednesday and hit the following Friday, which is quite good.

I am paid each week by standing order. The s/o leaves the AIB each wednesday and is in my B/I A/c each Thursday.
