I just transferred 298,000 miles from my
Chase Ink to
Singapore KrisFlyer and it was surprisingly fast! Not instant though.
Sent the request at 4:26 pm and at 6:41 pm (
2 hours and 15 minutes) I got an email from KrisFlyer welcoming me to the program after the miles transferred! I had just created a KrisFlyer account and this was my first transaction, which is why they emailed me when the points transferred (not sure if they normally do that).
I now have two roundtrip tickets in
Singapore Suites First Class LAX to NRT!
