Here's some advice I've given to people over the years and hopefully it will work for you. A day before or the day of the flight purchase a lottery ticket. You'll bring this ticket with you on your flight. Before you board have a look at the ticket and verbatim tell yourself this: as lucky as you would have to be to win with that lottery ticket, you would have to be even luckier for your plan to crash. You are not that lucky. Repeat as necessary but do not change the wording. This works for most people I've counseled.
