As someone who's been flying Delta a good amount recently (not by preference, but to the point of reaching silver medallion status), I know that Delta prioritizes high medallion status, which we all know the Trackers are not, especially for the 2020/21 time period since they didn't fly much. Unless they pulled the "do you know who am I" card to some poor ticket agent in Honolulu or Orlando (which wouldn't work, especially now in fraught traveling times), they paid for those tickets out-of-pocket and won't admit it.
The only other possible way they could get there is if they have a Delta credit card and used the miles accrued from that to more comfortably pay, since they could actually get miles off of their spendings, but that's unlikely for them, since Orlando isn't really a home-base for Delta Airlines and they'd be better suited for a different airline card (probably Southwest).
