Passengers have named Ryanair as the UK's "worst" short-haul airline in an annual survey by consumer group Which?.
In the survey, participants gave the budget airline the lowest possible rating for boarding, seat comfort, refreshments and cabin environment, leading to an overall customer score of 40 per cent.
More than two out of three participants named Ryanair as the one airline with which they would never travel.

It is the sixth year running the airline has been given the title of worst airline.
Other airlines at the bottom of the rankings for short-haul flights were Thomas Cook Airline at 52 per cent, Wizz Air with 54 per cent and British Airways who scored 56 per cent.
The airlines which scored highest in the survey included Aurigny with 81 per cent, Swiss Airlines with 80 per cent and Jet2 at 75 per cent.
Low-cost fares 'single most important factor'
A spokeswoman for Ryanair said the research did not take into account the low-cost fares, which she said were "the single most important factor" for UK consumers.
In December the Civil Aviation Authority launched enforcement action against Ryanair over its decision not to pay compensation for flight disruption resulting from industrial action by its staff during summer 2018.
The airline has also faced criticism for changing its hand luggage policy twice last year, resulting in charges for passengers flying with small wheelie suitcases.
