sure....perhaps that is the best way to do it. Just make an Excel spreadsheet with whatever you find relavent on the trip, (i.e. departure airport, destination airport, aircraft type and registration number, flight number, wheels up time, landing time, length of trip in miles and hours, seat and cabin of service, how much you paid for your ticket, quality of ride and service, pilot's signature, any comments you have regarding the trip, and anything else you can think of). In fact I actually did that for my flights when I was a kid.
