Chase UR Transfer Taking So Long (300k points)

I’ve been desperately trying to book award availability and transferred 300k points to British Airways. It’s been over 4 days and still no luck. I’m losing my mind over here.

Anyone have any experience of transferring that many miles and how long it took?

Any other advice or suggestions? I called Chase a few times and they told me expediting it wasn’t possible, but I’ve seen other people post about it. Id appreciate any ideas on how to actually get it expedited?

UPDATE: For those of you who are in the same boat, it took 6 business days to transfer, 8 regular days. I called a chase supervisor and was extremely frustrated with them, while still being respectful. I guess they pushed it that evening because a few hours later I got the points in my BA account.
