The major impact of coronavirus to airline travel has been seen over the last month or so.
According to the International Air Transport Association (IATA), domestic air travel is down by 70 percent worldwide.
The IATA says that domestic travel will rebound faster than long-haul flights but the impact of COVID-19 could cause the rebound to be slow.
