Although a couple has decided on having a casual wedding, sending out Save the date postcards can still be in order. A Save the date is sent as a courtesy to guests for when reservations may need to be made. A good rule of thumb is to send out the Save the dates 4 - 6 months before the wedding.
If multiple reservations are needed, i.e. hotel and airline, and/or if the wedding is during a peak travel time, i.e. around a holiday, then increasing that timeline will help your guests to make their plans.
