Prestige Class differences in Fare Basis Codes
I'm a Dl Plat considering a switch to KE, my standard run is HNL / BKK.
I usually buy the M on DL, 50k miles, and it runs $3500 nowadays.
I just booked for 12/1-12/8 and they had to sell me I/S on my return, no M class fares available to get upgrades with. So, the ticket is $4.3k. I knew KE had a cheaper product in pure Biz, and I've been told the actual product is better quality, so here goes.
I booked into Prestige and I got two choices, Prestige Promotional $3.855k with this Fare Basis (IXBZ) and Prestige Special at $4.123k with (DXBZA)
Does this just translate to an "I" and a "D" for purposes of Delta mileage multiplier and MQM's?
