As you've been saying all along, the midnight that occurs "on the day after" is the midnight at the beginning of the day. We can all agree that technically, every day's midnight occurs at the beginning of the day, but this doesn't appear to be Delta's interpretation.
If we interpret...
by midnight of the day after the eTicket is purchased
To mean "by the end of" the day after purchase. Then we must interpret...
or midnight of the departure date of the first flight
To mean "by the end of" the day of departure of the first flight.
