I am looking at JFK-SIN fares and find that:

a. DL comes up as close to $1800 (600+ is taxes and surcharges)

b. MU is $1250 and class shows XLX60AB*XKAP60CN*QEE3MUT

c. KE is $1350 and fare class shows as Q****

I cannot figure out if MU and KE fares above earn DL MQM (and how much?)
By looking at DL, KE appears to show Q as excluded

Can someone please help?

Regards.
