Trip planning comes to mind. If you have a bunch of booking sites, along with hotel information open, then you switch contexts to something like airfare booking. It's conceivable you want to eventually come back to the hotels if you haven't finished booking, and getting all X tabs open again would be helpful in that case so you don't have to individually remember all the hotels you were looking at.
If only sessions on travel-related websites didn't expire already after half an hour.
That's a good point, although some will re-search once the session is expired. It still helps with reference sites (like the hotel's/airline's/cruise's/etc page).
