The fully automated bag drop facility for customers is designed to help reduce and eliminate check-in queues.
"As a result of its introduction, queue times have reduced by half and more than 90% of our passengers will wait less than five minutes at bag drop," says the airline.
The 5,000sqm area contains 48 self-service bag drop kiosks and airline staff in the shape of easyJet 'welcome hosts' who are there to help and guide passengers through the process.
Today's official opening enables easyJet to fully consolidate its full operation at Gatwick to the North Terminal in January 2017, creating an easier and improved travel experience for passengers travelling from London Gatwick.
Sophie Dekkers, easyJet’s UK director, comments: "As our largest base Gatwick is of huge importance to easyJet both strategically and for the millions of our passengers who travel through the airport every year.
“We recognise that our customer’s airport experience is a crucial part of their overall journey and so we are delighted to have opened this new area for our customers flying from London Gatwick.
“Our vision is for Gatwick to be both our biggest and best airport and this opening enables us to further deliver on our ambition to make travel easy and affordable for all of our customers."
Gatwick's chief commercial officer, Guy Stephenson, says: “We are half way through a £2.5 billion programme of investment and the transformation of our North Terminal is a key part of this.
"Creating new spaces which allow new technology to speed passengers through the processing part of their journey will help us eliminate queues, handle greater numbers of passengers and put people in charge of how they spent their time at the airport”.
EasyJet started flying from London Gatwick Airport in 1999 and now has 60 aircraft based there, operating on 106 routes.
This year the airline will fly over 18 million passengers to and from Gatwick and has around 1400 cabin crew and 700 pilots operating from the airport.
