Travis took to his Facebook to announce the news:
I’m sorry to announce i won’t be joining Blink-182 on this Australian tour. I still haven’t gotten over the horrific events that took place the last time i flew when my plane crashed and 4 people were killed, two being my best friends. I gave the band my blessing to take another drummer if they still wanted to do the tour without me. I hope to come to Australia again some day perhaps by ship if need be. Unfortunately, there wasn’t a boat that worked with the schedule this time around. Once again I’m sorry to all the fans.
I think I speak for all of us when I say that we understand Travis. :(
