I had filed a flight plan for 8pm local the other night. I tried amending
the departure time as I was leaving 1.5 hours later than the proposed
time. I called the FSS and was told the IFR flight plan gets deleted by
the system 2 hours after the proposed departure time. I thought it was 45
minutes or an hour. My friend who thought it was 2 hours. The only
reference I can find says it varies from center to center. Is this
correct? Any real world experience?

And if this is in the Pilot-Controller handbook, it's time for me to buy
it and I apologize in advance.


The national standard is two hours. That can be extended by individual
ARTCCs and is often done during periods of weather delays. It's not in the
Pilot/Controller Glossary.
