spread sheet at the end. now when i travel, i have no issues. it's all taken care of split wise. >> one way i like to stay organized is i use an app called trip it pro. trip it is an app that will synch with your inbox. it will input all your travel information and itineraries. i click into the app, everything i need to know is right there. i don't worry about documents. looking for e-mails. everything i need is in one easy place. it gives me the latest, up to date travel information. i know if train times have changed. if things are delayed. it's superuseful.
