Sharing BB Calander with another BB user

Is there a way that I can allow my girlfriend to see my BB calender on her BB without inviting her to all my appointments. I travel a lot and would like her to see my flights and where I am, including after work meetings and the gym etc. I do not want to use Google Calendar as that would be the 5th calendar I have to update, and she doesnt have to attend all the events so I just want them to be viewable.

make a bb group and share whatever appts you want in that group with just the 2 of you ?

+1 on the BBM Group.

My wife and I use a BBM Group to keep the family schedule on our BBs, plus use lists for things like the grocery list, honey-do list, and so on.

I use Gmail calendar with my wife, and her iPhone.

all syncs both ways and it's accessible online as well.
