London Gatwick will open its new North Terminal departures level in October 2015.
The 8,000 sqm area includes the world's largest self-service bag drop zone which has the goal to eliminate queues.
Operational testing will be on-going for the first two weeks of October 2015 before gradually opening from 20 October 2015 with a one-month trial period ending on 18 November 2015.
The check-in hall will open in two phases between October 2015 and April 2016.
There will be 60 check-in points, 48 of which will be self-service bag drop units that can complete the check-in process "in less than two minutes". 28 self-service units will be available for use when the new level opens in October 2015.
Elsewhere, features include a new staircase linking the ground floor arrivals with the first floor transit shuttle to/from the train station, a new escalator, new flooring, 400 metres of new baggage belts, and new shops.
Next summer will see a new security area that Gatwick claims will halve passenger transit times and enable it to process 5,000 people each hour and a fully-refurbished arrival area.
Other works in progress include a new departure lounge, more retail and restaurant space, 15 new e-gates, a reconfigured Pier 5 facility and a new Pier 1.
