Although under the temporary status accelerator promotion, Basic Economy and Main Cabin get a 50% bonus and Comfort+, Premium Select, First Class, and Delta One get a 75% bonus. The bonus is applied after the cabin bonus, so the MQM chart ends up looking like:
Basic Economy: 150% of miles flown
Main Cabin (most fare classes)
: 150% of miles flown
Main Cabin (Y or B class)
: 225% of miles flown
Comfort+: 175% of miles flown
Premium Select: 262.5% of miles flown
First Class or Delta One (most fare classes)
: 262.5% of miles flown
First Class or Delta One (J or F class): 350% of miles flown
