What curfews?! MAD is not FRA or LHR and has no curfews.
As you correctly pointed out, it has to do more with connections and plane utilization.
What really sucks IMO is lack of redeyes going westbound to the west coast, leaving at 2AM from, say, LHR and getting to SFO/LAX around 5-6AM. Again this also has to do with connections and fleet utilization, although, IMO, this is much more sensible than having LHR-SFO leave at noon or even 3PM.
