TripIt Pro offers flight delay alerts, help finding alternate flights if yours is canceled, frequent-travel-program point tracking, auto sharing and refund notification if your airfare becomes eligible. You can share trip details with other TripIt members using a free account, although you'll be prodded to sign up for Pro.

If you use multiple platforms, additions and changes made in your TripIt account on one device are synced everywhere. And mobile apps don't need to be connected to the Internet to view the information -- just update and sync ahead of time.

If you plan your own travel and don't enjoy keeping track of multiple confirmation emails for a trip, TripIt can be a useful assistant.
