Three days, a week, ... any time

We’ve even had a “one flight” PP event, cut up in about 20 separate flights, spread out over several weeks once.
You can make intermediate landings, even close your Sim and shut down your computer. Next time you fire up the sim and FL, it continues to record that same flight. Be sure to Save your FS situation before you shut down the sim, so you can easily pick up where you left off.
You can only file your PIREP once on the ground at your destination with the engine(s) shut off. So you can shut off your engines at each intermediate location, but the you cannot file your PIREP yet.
Oh, and don’t sorry about the time gap warning you might get upon filing the PIREP. It just causes the need for me to manually approve the PIREP, so it might take a day or two. Efore it appears in your flight logs. I always approve them
