IF YOU have grown accustomed to being waved into an expedited security line at the airport this year even though you didn't belong to the Transportation Security Administration's PreCheck programme, you should probably get ready to take your shoes off again at the checkpoints next year.

More than 45 per cent of air travellers now move quickly through security by using PreCheck or other so-called risk-based programmes. And the TSA says that it has enrolled so many travellers in PreCheck, which costs US$85 for five years, that it is reducing the numbers of nonmembers being allowed to use those lanes.
