The low-cost carrier cancelled 54 flights on Sunday (11 June) with another 55 to be axed on Monday as thunderstorms across the south of England caused "disruption at London Gatwick airport, including including some diversions and cancellations which is having a knock-on impact this morning as a number of aircraft are out of position."

“Due to unsettled weather conditions and thunderstorms across the south of England and Europe yesterday, temporary air traffic restrictions were put in place, which resulted in some flights being delayed and cancelled,” added an airport spokesperson.

“London Gatwick apologises to passengers for any inconvenience. Further thunderstorms are expected today, so passengers should contact their airline for further information."

EasyJet added that cancellations were “an extraordinary circumstance" outside of its control, meaning the airline is not legally required to offer passengers a refund.

Nevertheless, the airline said it was doing "all possible" to minimise the impact on customers. 

The announcement came as consumer champion Which? called on easyJet to offer passengers either a refund or the option to be transferred onto another flight.

“While easyJet does not have to pay compensation for these cancellations, it must offer affected passengers the option of a refund or to be rerouted at the earliest opportunity - even if this means booking seats with a rival carrier to ensure minimal delay,” said deputy editor Jo Rhodes.

“If delayed for more than two hours, passengers will be entitled to assistance such as free meals or refreshments, and overnight accommodation if required."
