Delta CEO Ed Bastian doesn't expect travel demand to rise in the next few months

"I would expect that the travel we're going to be seeing for the upcoming Christmas period is going to be similar to what we've experienced over the last few weeks," Delta Air Lines CEO Ed Bastian told CNBC's "Squawk on the Street" Wednesday. "We're currently at about one-third of normal traffic trends and I don't see that changing here for the next couple of months."
