The body of a brain-dead person is usually not supported for very long, Greene-Chandos said. Doctors sometimes provide support (in the form of a ventilator, hormones, fluids, etc.) for several days if the organs will be used for donation, or if the family needs more time to say good-bye, Greene-Chandos said.
If you do get approved for TSA Pre-Check, you can choose to receive your Known Traveler Number (KTN) either through the mail or online. When booking flights from airports that support Pre-Check, be sure to do so with an airline that TSA Pre-Check covers, and be sure to enter in your KTN. Your TSA Pre-Check eligibility is valid for 5 years, after which you will have to re-apply.
Once you receive your KTN, you'll be able to swish on by long security lines at 120 airports and get into the specially designated TSA PreCheck line. Skip some common security checks, keep your shoes and belt on, keep your laptop in your carry on, and try not to gloat. TSA PreCheck approval lasts for five years.
