There aren't any safety question marks about easyJet. I've no idea where the 'Airlineratings' website gets its ideas from, but the idea that easyJet is an unsafe airline is absurd.

The airline is based in the UK, and is subject to tight European air safety regulation. It is the second largest airline in Europe by number of passengers carried (and by the same measure the largest UK airline).

easyJet also has a good record of reliability and punctuality. The last time I was significantly delayed when flying easyJet was when there was very bad weather in the London area (and I was flying back into a London airport) - if anything that showed that they were taking safety seriously, and the flights of other airlines were all similarly disrupted.
