London, Nov 8 - Johnny Depp has revealed he prefers to fly on private planes so that he can smoke.

"On a private plane you can smoke and this makes it an incredibly expensive habit," femalefirst. co. uk quoted Depp as saying.

"Also, with the commercial flight thing, it just gets a little weird when you're standing in line and suddenly you're not just a guy standing in line any more, you become sort of unusual to people, who start staring at you," he added.

The 48-year-old actor gave up smoking for two-and-a-half years and only took up the habit again after working on "The Rum Diary". (IANS)
