JetJock. Review your FTL's and the OMA. You can not legally complete a split duty day with less than 3 hours rest in the hotel. Time spent travelling back and forth and your 30 minutes post flight and 1 hr preflight can't count.
DEL must be 4 hrs 30 minutes minimum block to block plus travel time to the hotel to give you 30 minutes rest. Don't accept any less.
