SoCalFlyer97 uses two tabs on a desktop machine to shop/book flights not necessarily to save time but the intent for me is to save me from seeing numerous "Don't forget to book your trip" emails in my inbox.
When I go through the Low Fare Calendar, I'll open up a new browsing window and shop in incognito mode. Once I find something, I'll login from my standard window and book the flight. That way, if I'm looking up my different date and airport options a decide to opt out of the higher priced options, it won't trigger this email.
