When NOT logged into my FlightAware account, Worldwide Airport Delays and Airport Status - FlightAware tells me
Total delays within, into, or out of the United States today: 2,133
However if I log in to my account, that same page says
Total delays within, into, or out of the United States today: 0
It’s been showing 0 for at least the part 24 hours, but only when logged in. Bug?
