TSA Pre Approval?

That's a very firm 'That depends....'
It depends how much you value your time. Pre-check will save you between 5 minutes and an hour going through security.
It depends how much you value your privacy. Pre-check will insist on knowing a lot more about you and your background.
It depends how much you value your serenity. Pre-check is a much more hassle-free experience.
It depends how much you value your money. Pre-check costs $100 for five years.
And Pre-check comes with Global Entry, which will save you time and hassle getting through US Customs.

Although I don't fly much I use it because I need air travel to be as stress-free as possible.
