Denver International Airport (DIA) may be one of the first US airports to be permitted to sell advertising on the security bins that pass through X-ray machines.

DIA has already applied for approval to take part in a test scheme where advertisers are allowed to display their messages, in return for paying for the airport's new bins, security tables and carts.
The idea originally came from the Transportation Security Administration (TSA) who launched a pilot programme at Los Angeles International Airport last year.
