AC1063 AUS-YVR.
AE booking, I actually tried booking in Standard, Flex, and latitude to see if it impacted LMU price (since I like to book less than 24hrs before departure). All 3 fares offered an LMU price of 261 USD. Pretty good deal but I went for a latitude+4 eups instead. Flight was J2 R2 when I tried this.
