According to a recent article on Blabbermouth:
TOOL drummer Danny Carey told The Pulse of Radio that unlike some groups, the members of the band still travel together on the road. “We pretty much all travel together,” he said. “We kind of have to, you know, just for the logistics of everything going down. The schedule gets pretty tight, especially at the beginning of the tour, ’cause there are lots of interviews and, you know, soundchecks. Everything’s pretty scheduled out. We’re on a bus pretty much all the time in Europe. In America it varies. Sometimes we fly, sometimes we bus it.”
I also mentions that Lollapalooza is the last scheduled show. Not sure how much I read into that comment, I think they’re talking in regards to the dates provided so far – I expect there will be further shows after that festival gig.
