Despite the assurances from the company that all containers are checked, I do think that this is not a good way forward.
Yes, the luggage is checked by x ray. Yes, the crew and cleaners etc are security checked, but the fact remains that these containers are a vulnerable route for unscrupulous people to get items onto an aeroplane.
The other downside is that if the crew find things missing, who suffers - the passengers - who pays our wages - the passengers - who won't book with us again - the passengers !
