Best practice
Use "I will have left" to clearly indicate that the action of leaving will be completed before a specific time or event in the future. This helps avoid ambiguity about the timing of your departure.
Common error
Avoid using the simple future tense ("I will leave") when you need to emphasize the completion of the action before another future event. "I will leave" suggests the act of leaving itself, not necessarily its completion by a certain time.
