To protect from shifting in-flight or draining the battery, would unplugging the front and rear derailleurs be enough? Do I need to do anything with the shifters or unplug the junction box?

I've double-checked the airline policy and the Di2 battery is well below their allowed watt-hour limit for in-equipment batteries.
