It's easy enough to figure out where your flight is coming from if it's
making a stop at your originating airport and keeping the same flight
number as it continues on to your destination.

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.

i check the arrivals and departure board myself. Find the gate your
flight is supposed to leave from (sometimes you will get a/c changes so
even if the a/c is supposed to fly, say, DTW-MSP-SEA, there might be an
impromtu a/c change in MSP if the DTW-MSP flight is late.
