I've just noticed while looking through Delta.com that they have a second flight operating from DTW-LHR.
Seems to be Delta flight 56 - 57 on the LHR-DTW leg.
When did this flight start? Are the loads on the DL5/6 that good that they added a second service?
Seems to operate everyother day rather than daily.
Haven't seen anything on here about this so thought i'd ask.
