Qantas cancelled a flight from Rome to Perth on Saturday after passengers on the previous leg complained of bedbug bites, the BBC and The Independent reported. The airline said the Boeing 787 Dreamliner was taken out of service so engineers could carry out a "deep clean."
Passengers booked on the cancelled service were given accommodation and rebooked on other flights within 48 hours of their original departure, according to the carrier.
A Qantas spokesperson told the BBC the airline apologized to customers for the cancellation. The statement said the grounding let engineers and maintenance staff clean the aircraft after an issue was found on a small number of economy seats. The airline did not disclose how many passengers were affected.
The Independent also reported that Qantas says it cleans its aircraft regularly and disinfects them every 50 days as a precaution.
For passengers caught up in the Qantas cancellation, the practical result was a delay of up to two days, with hotel stays and new bookings arranged by the airline. The disruption also shows how a problem with a small number of seats can take a long-haul aircraft out of service.
On the health side, the NHS website says bedbug bites can be itchy but do not usually cause more serious problems. Australia's Victorian government Better Health Channel says bedbugs are not believed to transmit diseases to humans. It describes a bite as typically a large, reddened and itchy welt that fades to a red spot, though some people do not react at all.
Bedbugs are small, wingless insects that feed on blood and can travel on clothing, suitcases and bedding, according to The Independent. The BBC, citing the NHS, noted that they can be difficult and expensive to remove. Its suggested treatments include washing bedding, clothing and fabrics such as curtains on a hot wash and tumble drying them, or sealing items in plastic bags in a freezer for three or four days.
