Overall, I guess there are differences between booking rules with cash & miles.?
Long-haul international revenue fares and awards allow up to 24 hour layovers. Not really the same thing being talked about here with 4 hours on US48 domestic fares. Also, DL just recently reduced layover allowance on Mexico/Caribbean/Central America for both revenue fares and awards to 6 hours (previously, it had been 16 hours for Mexico and 24 hours for Caribbean/Central America except for SJU/STT/STX). See this thread --
Award booking of DL flights - $200 extra charge
DL does seem to more readily quote broken fare awards vs. broken fare revenue fares. The layover allowances are still there for awards. But it's not always obvious you are getting a broken fare award unless you click through to the fare rules to see the actual award fare contruction. Although when the award classes are different on flights, it's fairly obvious.
