It's Captain Travolta urging Americans to take to the friendly skies on his favorite carrier, Qantas Airlines.

"Extra" caught up with John in San Francisco as he inaugurated Quantas' new direct rout from the Bay Area to the outback. "I could hop in there right now and fly you anywhere you'd like," Travolta said. "Australia is the number one desired destination of the United States."

The 52-year-old superstar sent his love to good friend and fellow flight enthusiast, Tom Cruise. John even shed some light on rumors of a Scientology-inspired "silent" birth for Tom and Katie's baby.

"It's just unwanted input at a painful moment in someones life," Travolta explained. "You don't want to contribute more to it."

Travolta was eager to break news of his own, confirming to "Extra" that he will indeed play J.R. Ewing in the big-screen version of "Dallas."

"I have to do two movies before," he said. "That one is called ?'Wild Hogs,' a motorcycle movie, a comedy with Tim Allen. The other one is ?'Hairspray,' and then I'll do ?'Dallas.'"

Jennifer Lopez is reportedly up for the role of J.R.'s wife Sue Ellen, and that would explain the pair's chatty encounter at Vanity Fair's post-Oscar bash. "Yes, I did speak to J Lo," Travolta revealed. "She's interested, and I'm hoping they're closing her deal as well."

And yes, Travolta will be in full drag when he tackles the role of Edna in "Hairspray." And he hopes a few famous friends will join him. "I think Billy Crystal is doing it as well as maybe Michelle Pfeiffer," he revealed. "I'm all set for this year. It's going to be busy."
