I will be soon flying with Ryanair from the UK and realized that I will be carrying a toner cartridge for a laser printer. Interestingly, in 2010 there was a foiled plan that involved turning toner cartridges into bombs. Soon after carrying a package with more than 500g was banned, at least initially.
I have searched the airport website, the website of Ryanair and generally the 'net, but I cannot find anything about the current situation: it appears as though nobody cares about toner anymore. Could someone clarify whether there are currently any restrictions on carrying toner cartridges?
