Heh. If not MSP crew, prolly NYC, they already fly JFK-KEF & vice versa. Given the timing of the flights it appears they intend to route one plane MSP-KEF-JFK and the other opposite. Interestingly Icelandair already flies MSP-KEF a couple times a week in the summer, also in a 757-200. I figured they were able to fill it with connecting traffic to continental Europe... I guess DL thinks there's enough traffic headed just to Iceland to justify a second flight to KEF.

Spent a week in Iceland this summer. Beautiful country, beautiful women, fun city in Reykjavik.
