The simple, and usual solution at most airlines is to make it "not" account for DST, as in making departure at the same time in relation to UTC. If it leaves at 10:00 before, now it leaves at 09:00. Usually it changes on the DST observing side, or if both sides observe DST, the side with that observed it first changed for, the side that isn't the headquarters, or the side with the less busy airport.
If this is blanket implemented in Airline Enterprise, it will screw up people flight demand for those who depart between 5-6 am, since that will shift them into 4-5 am in the Fall.
The other option is to let us schedule according to UTC time, instead of the local time.
