Any suggetsions on how to figure out where your flight is originating from?
This is handy information to have when cutting through the mountains of BS
gate agents can be so adept at generating when there is a delay, especially
when it's lots of delays masking an eventual cancellation.

It be great if there were a website you could lookup the tail number that
the airline has assigned to a particular flight and then find out where
that aircraft REALLY is.
