TripIt continues to lead the pack in organizing travel itineraries. By pulling all of your plans together in one place and making them accessible across all your devices, TripIt is a complete solution. Purchased by popular corporate travel site Concur in January for $120 million, it only continues to improve. Travelers can forward e-mails to after they've created an account and booked the travel, and TripIt does the remainder of the work. TripIt Pro offers flight alerts often quicker than the airlines themselves, along with allowing you to organize reward programs, check on baggage, and more. TripIt for Business allows visibility into employee travel for small- and medium-sized businesses. Lastly, integrated easily with LinkedIn, Facebook and more, you can see when you and your connections are going to be in the same place, making networking even easier.

COST: Free; TripIt Pro, $49 per year; TripIt for Business, $29 to $159 per month.
