3K points from a flight last week posted 2 days after the flight. Happy with that as I was expecting to need to make a claim.
On a side note, this was my first 3K flight, so a few observations. Found staff to be more engaging than JQ, YMMV. Exit row seat was worth the $20 for the HKG-SIN leg at just under 4 hours. A320 seemed new, was in very good condition. Enjoyed access to HKG lounge, which wasn't too busy even with QF30 and 128 pax. Only aspects of 'true LCC' feel were remote boarding at HKG and the meal provided. I was on Starter Plus, so meal and points inclusive. I did intentionally eat up in the lounge as I wasn't expecting much on the plane. I'm still trying to work out what part of the chicken was actually served....
I would consider 3K again for intra-Asia flights, obviously depending on price and lounge access. This fare was only $140 including the exit row seating and plus package.
