I like how it’s easy for you as an airline employee or manager to create your own flight operations documents with this software. It's also pretty cheap compared to competing programs (I think we paid around $100 per user). Some of my customers have been asking about what other apps they should use, so hopefully that will be included in their next version! Honestly there aren't too many downsides at all. Take advantage when these types are available because its very useful! Easy access from mobile devices/apps is one thing I appreciate since most of our staff uses them while working away in various locations during normal hours. The ability for us as an airline provider, with our own fleet of aircrafts (in addition other third party providers), is very easy from this platform! We have been using it since last year in production use at Lufthansa Group Germany where we manage all flight operations tasks related activities such like crew scheduling/crew changeover etc., including maintenance management via OMSI or MOMSIS system integration also possible through coreana FLS product range!
