Our airline uses charterlog extensively throughout our fleet - we can see where fuel was purchased in each state (including domestic), which states are at maximum capacity with aircraft already present there etc., as well as all other pertinent info such us departure time & arrival dates from previous flights along my route so I know when it will be appropriate or not make changes during layovers if necessary! If you have an easy way that allows multiple users access via different devices this helps tremendously while traveling across several countries without everyone having their own logbook open up next door!! Sometimes they don't sync properly but luckily its been pretty rare lately since moving away towards google drive instead now.- Flight details aren’t always correct due date errors being fixed manually rather than automatically corrected through automation or some sort like Google Sheets would help immensely too.
