It seems there will be a change with the way the MQD (Medallion Qualifying Dollar) waiver will be factored in for the 2019 Medallion year. Instead of needing the $25,000 spend on your Delta-branded American Express card, you will now need $250,000. As most of my MQD are accrued by flight purchases thanks to work I am not too worried, but this is a pretty big jump in qualification criteria from past years.
I’m kind of curious to see if/how other airlines update their policies in kind.
