All times are approximate for indoors, putting balloons outside can reduce the time by 50%. Another factor is the actual size of the balloon. Inflating too much will cause them to burst in 5-10 minutes. Inflating too little will reduce flying time. Other factors include temperature, humidity, sunlight and children with sharp objects.
