London calling: not so fast

News of the imminent, widespread return of the personal item to carry-on travelers in the UK has been greatly exxagerated:

A plan to ease the one-piece cabin baggage restriction for airline passengers in January could lead to mass confusion, airport officials say.

The Department for Transport has said more than one piece will be allowed after 7 January, provided airports have purchased improved security scanners.

Yet airport operators say it is also up to airlines to decide if they want more cabin baggage on board flights. - BBC

Did you catch the poison pill? UK airports must have the new 3D-imaging x-ray scanners in place to allow the personal item. I’ll bet that means the change will come slowly to Heathrow and who-knows-when everywhere else. In the meantime assume that one bag really means ONE bag.
