Livid holidaymakers took to social media in their thousands today to vent about massive queues at the London airport, located in Essex, following torrential downpours on Friday.
Delays worsened overnight as high passenger numbers and air traffic control staff shortages took effect.
Passenger Mitch Emburey wrote on Twitter: “Flights cancelled, poor information. Cattle market system at Stansted Airport. @STN_Airport Its 2018 not 1818.”
Delays due to the extreme weather also spread to other UK airports, while travellers faced travel misery on Eurotunnel and ferry crossings.
