Secret filming at Jersey Airport by the BBC’s Watchdog programme revealed last night that Bmibaby’s measuring bins for hand baggage were smaller at the gate than at check-in. They were also smaller than the dimensions given for hand baggage on the budget airline’s own website.

The airline has admitted that there is a design fault with its gauges and plans to replace them with a correct version. Passengers who think they may have been unfairly charged can write to bmibaby to ask for a refund.
