I’m not sure why you say it’s for business. I do a lot of business and personal travel and it’s great for both. Organizing trips with friends and family is much easier to coordinate with tripit and my boss couldn’t care less which hotel/flight I’m on.
The pro features specifically is mostly just alerting, not tied to personal/business.
I have never used the sharing features much. I say business but perhaps what I mean is frequent travel. I.e. having enough flights and hotels on your calendar that they're hard (or at least a bear) to keep track of.
