Is there an easy way somewhere to figure out when planes change flight numbers on Horizon? For instance, I'm flying out tonight from Portland to Seattle on Flight 2606. I know that flight originates in Portland. I'd like to find out what flight that plane was used on previous to my flight, so I can set up a flight tracker for it. If that plane is late, then I can probably interpolate that might flight is going to be late too.

Ideas?

Thanks.
