For pilots, I believe www.jetcareers.com (By Doug Taylor) might have some of that info.
For FA's: here it goes!
(all info pertains to UA)-FA's must checkin about 1:30 (one hour thirty minutes) before scheduled departure. The check in time varies with the route, time of day, and aircraft flown (widebody vs narrowbody). Once you check in for the flight, a briefing is held with all FA's working the trip. The purser will introduce all the crewmembers, give any information pertaining to the procedures, products and services aboard, and assign duties (such as greeting the pax, be incharge of government documents[internationally], be incharge of unaccompanied minors, etc). Then (on international flights only), duty breaks will be assigned to the different flightattendants.
Approximately 60 minutes before departure (intl), the FA's will board the plane and do their safety checks (which, prior to contrary belief, do NOT include looking for life vests and making sure pillows are on each seat!) such as: "preflighting" the safety equipment such as fire extinguishers, emergency flashlights (making sure that they are operable and the pressure is in the "good range"). They will also check the door pressure gages to make sure that if they need to evacuate, there will be enough force in the slides to deploy them.
After all the saftey checks are done (there are SO many to do!), generally, pax. boarding will commence. During this time, the FA's working the galleys on the trip will do a quick meal count to make sure that there's enough food, check the liquor supplies, start in on liquor paperwork, and do anything they need to do to quickly start the service once airborne.
Internationally (domestic is much worse!), the work month will be between three and four 3-day trips (so 9-12 working days/month), which would be SFO-NRT, LHR (KIX is a four-day trip), or two 5-day trips (SFO, LAX-SYD, AKL, MEL) followed by one 1-day or one 2-day trip to Hawaii (LAX, SFO-Hawaii). Basically--International FA's don't work more than 12 days/month.
I will try and dig up some domestic trip lines to see how many days they're working!
