I've tried to search threads, but can't find an answer to this question. I have a flight in a couple of weeks that departs at 10:55 a.m. Is there a way to determine if this is an originating verus thru flight?

I normally fly this rounte on a 6AM flight, which is always an originating flight....but I doubt a 10:55 flight would be originating? Any ideas how I can confirm? Thank you!
