One thing to keep in mind is that security at TBIT, particularly at peak times, can be pretty terrible. I don't know if DL SkyPriority will get you into the TBIT priority line...
The landside checkin counters are like any modern airport you've been to, and the 30 seconds you'll save the next time you pass through IMO aren't worth it. I'd clear security in T5 after dropping the bag with DL, then walk over airside to do the planespotting.
