"WorldMate works on two levels. On installing, the majority of the functions are freely available. Updating to the pro version (which is $50 for a twelve month licence) will give you access to the latest additions to WorldMate 'Professional', namely the ability to manage your flight schedules, look up new flights and airline timetables, and to set up alerts when flights are delayed or cancelled.By telling WorldMate which flights you are booked on for your next trip, you will, if they are delayed or cancelled, get an alert sent to the application as soon as is practical. This is a perfect example of an application that is utterly useless 99.95% of the time, yet the one time it does work is when you realize you’ll be adding your flights for the rest of the annual subscription period, and, more than likely, be renewing it for subsequent years."
