Airlines have cancelled flights to Italy and other parts of Europe since officials announced an increased risk from COVID-19.
Ryanair, easyJet and British Airways have reduced their services to Italy since the major outbreak there has resulted in some towns being put on lockdown.
Hundreds of flights to other destinations including France, Germany, Switzerland and Austria have also been cut as increasing numbers of passengers decide not to travel.
Affected passengers are entitled to rebook alternative flights free of charge, or cancel altogether and get a refund.
The cancellations are a result of airlines reporting a drop in demand and a significant number of passenger no-shows.
Many holidaymakers and 'non-essential' travellers are now abandoning their travel plans.
This isn't an exhaustive list, so check with your airline before travelling.
All of the airlines have said affected customers will be contacted directly. Alternative travel can be arranged, or flights will be refunded.
Although you'll be entitled to your money back for the cost of the flight, many passengers with cancelled flights may not be eligible for cancellation compensation.
As long as an airline gives 14 days' notice of any flight cancellations, it isn't obliged to pay out.
Most of the cancellations recently announced have been within the 14 days required notice.
If your flight isn't cancelled, but you're worried about the risks of travelling and want to cancel, ask your airline if it will allow you to rebook.
Although airlines don't have to refund or rebook you in this case, we've heard some are allowing passengers to postpone travel in light of the situation, so it's worth checking.
