After the service, I took a look at the fluids in the car. There is a tank marked coolant with F and L marks on it, and the the level of fluid in this tank was (significantly) below the L mark - it looks like there are about two cups total at the very bottom.
This means that you can book a round-trip ticket to Hawaii from anywhere Delta flies in the US, Canada, Mexico, Puerto Rico, or US Virgin Islands using Korean Air miles for only 25,000 miles in coach or 45,000 miles in Business Class.
While itâs much easier to redeem miles in a program that doesnât pass on fuel surcharges, the fact is, we have miles in other programs. So the key here is to use those miles on partner airlines that donât have fuel surcharges to pass on.In some respects itâs easy if you just know the airlines to redeem on. left Delta where I flew 75K-100K miles per year international due to fuel surcharges on trips originating outside US, and changes to their program that demonstrated a lack of integrity. Used to BA Gold regularly too, but got tired of the high fuel surcharges, so I no longer fly them.
