Following a pilot at various US airports, the Transportation Security Administration (TSA) has rejected four security scanners, meaning passengers must continue to remove their footwear at security checkpoints.
It had been hoped that the trial of the scanners – which are designed to detect explosives and metal items – would lead to a change in the current airport security process. However, the rejection of the scanners means that the current security process will remain in place for the foreseeable future.
In an attempt to expedite the security process and reduce queues, the TSA last year introduced the TSA PreCheck programme. This programme is currently available at more than 20 US airports, including Seattle-Tacoma Airport.
