I've been a huge fan of the details I'm seeing through Altitude!
For those of us not interested in shopping all week for a good low fare, this is the product to use. Join, set preferences and travel when you want.
I have had beta access for a few months. I have learned all of my travel tips from @chasefoto who is now opening up his knowledge to share!
Got access to the open beta a couple of months ago. Really enjoy the ease of use and variety of deals that come through. Looking forward to the blog and tutorials rolling out.
