Ryanair has been voted the dirtiest UK airline, according to a new study.
A survey found that only 42% of passengers rated the budget airline for cleanliness onboard.
A quarter of passengers – 24% – claimed that cleanliness onboard was poor.
The figures come in a new survey from Which? Travel which questioned almost 8,000 people online during September and October 2018 to find the dirtiest airlines.
A Which? investigator who boarded a Ryanair flight reported ‘greasy tray tables, soiled headrests and dusty window sills’.
They added that when they used an ultraviolet light to look at how clean the tray tables were, it showed stains that couldn’t be seen by the naked eye.
The Irish company was said to be ‘significantly worse’ than dozens of other airlines in the study.
In the poll, it was said that on average eight out of 10 (81%) passengers rated cleanliness positively across 42 airlines.
Six in 10 passengers – 62% – found Wizz Air planes to be clean, while across both Wizz Air and Vueling, one in 10 people rated cabin cleanliness as ‘poor’.
In comparison, 63% of people flying with Spanish airlines Vueling and Iberia felt cleanliness was good.
British Airways and easyjet were both said to have good levels of hygiene onboard, while Air New Zealand, Singapore Airlines, Qatar Airways, Cathay Pacific, Swiss and Emirates all scored over 90%.
Rory Boland, Which? Travel editor said: ‘Faster and faster turnarounds are one thing but it is unacceptable for some airlines to be cutting corners when it comes to cleaning out their cabins properly – no matter how cheap the airline ticket.
‘There are steps you can take; either choose your next flight on an airline that has a good track record for cleanliness or equip yourself with some antibacterial wipes.
‘If you are flying Ryanair though, a biohazard suit might be more appropriate.’
