I also don't doubt the info about the fuel reserves for diversion readiness.

I like to track squawks, and there are more diversions than people realize.

Of course, it's important to know that a diverted flight can't just "roll up" to the airport and land, so to speak.

I have watched many flight patterns where diversions are complicated by multiple repeated "circles" aloft after reaching the accepting airfield, waiting for a chance to land.

The extra fuel comes in very handy in those situations. ✈️❤️
