Is it possible to see a snapshot of airspace as it was?

I saw an interesting pair of contrails in the sky yesterday and didn’t look up the flights at the time. Now, today, I am wondering where those two flights were going. I am in YYC, but the historical YYC data is no good because neither flight was arriving or departing as they were at cruising altitude so were just passing overhead. I know the time, so is there a way to figure out what the flights were?
