Where luggage doesn’t show up, you should be able to monitor it through the tracing procedure, either by contacting baggage services at the airport, the airline’s central department or by logging into an online baggage-tracing page with a reference number. This reference will relate to the luggage receipt usually attached to your passport or boarding card at check-in or bag-drop, so you’ll need to keep it to hand. (Telegraph)
