You'll just have to book a flight at least 3 days in advance, and off you go. Cancellation fees and penalties apply in pretty much the standard fashion, with one addition: no-showing for a flight will get your pass suspended until you pony up a $100 penalty. (We're pretty sure that never happens with bus passes.)
While you're plotting to get some productive business travel in, remember too that JetBlue flies all over North America, and to a number of Caribbean destinations as well. The All-You-Can-Jet deal will impose a little bit extra in taxes for international flights, but you could quite easily use your jet pass to sneak in a little beachside vacation too.
The passes are on sale now, and will be until August 21, or until they run out. No word on just how many JetBlue is planning to sell.
