Is there any way to look up specifics of prior flight info on delta.com? (e.g., I'm hoping to find what type of airplane, departure time, arrival time, what seat I was in, etc.)

If I go to "Account Activity" I can see past legs and flight numbers, but no additional information. I've also tried flightaware.com, but their data only goes back 4 months.

Thoughts? Suggestions? Thank you!
