According to my algorithm first there it has been understood that departureplace, arrival place, date and time of departure, date and time of arrival andtime difference should be given by user and with correct validated data thatis date and time should be in proper format and all of the data ismandatory. Then store the value of each value in a different variable andwill be consistent for whole algorithm. The flight time variable has to vary itsvalue according to the situation.
