From today, easyJet passengers are warned that the only way to be sure that a carry-on bag will actually travel in the cabin is to make it 36 per cent smaller than the current maximum permitted dimensions.
The airline says they will guarantee your hand luggage will travel on the plane with you in the cabin if it fits the new, smaller restrictions. But, if it's too big and is of the old slightly larger size, there's a chance it could go into the hold, which means having to wait for it to come off the carousel.
So, does it just mean another confusing concept for low-cost airline passengers? We're joined by Simon Calder, travel editor of The Independent, and Peter Duffy, marketing director of easyJet to get the lowdown.
