I like how easy it was for me as an employee of this program (and not using another service)to keep up with all our flights in one place! The best part? It's free!! There isn't much we dislike about MyFlightData; however there could be some minor issues here or things added/removed from future versions but everything seems pretty good so far. This has been great because now when someone forgets their logbook they can just go online instead without having them look through old paper logs which would take longer than simply logging into MFD anyways :).
