If predictability and price is your main concern, by one round trip returning 15 July and a one way returning 19 July. Buy whichever itineraries are less expensive. For the segment you don’t fly, you should still be able to use some of the fare for future travel, minus any fees.
This is not an overlapping itinerary, which isn’t usually a problem, so you can book this with the same airline, but you will probably find the airline offering a reasonable one-way fare will not be the airline that offers the best round trip fare.
