Hello,

I've got a Fare Lock that's about to expire for a trip from EWR to MIA for my family and my Sapphire miles are taking a while to transfer to MileagePlus. I read online that it's usually instant, but we're going on the 3rd day. I've got a $1,500 voucher that I can use, so I'm wondering a few things:

A) How long do Sapphire miles usually take to transfer? Any way to push them through?
B) Should I put half the tickets on miles and half on a $1,500 voucher I have?
C) If I do thing B and the points come through, can I do anything to use them instead of the voucher? My sense is that it's not 1:1.

Thanks for help - called both United and Chase and they haven't been very helpful.
