A £50m overhaul of Terminal One at Manchester Airport has been completed - based on the advice of psychologists.
The experts helped assess where travellers may experience stress before going on holiday - such as car parking, security and check-in.
The two-year project includes enlarged "airside" shopping areas, scanners and facial recognition computers.
The tightened security climate has seen the airport abolishing shops sited before security check points.
Andrew Cornish, managing director for Manchester Airport, said: "Our terminal redesigns have had to withstand the test of time with the liquid ban and the terrorist attack on Glasgow Airport."
The new airside retail and catering areas on the departures level is larger than the pedestrian zones of King Street and Market Street in Manchester city centre.
On top of the changes, a new Emirates lounge, boarding area and a range of gates are to be added to the terminal, in preparation for Airbus A380 flights which are expected to begin operating from Manchester within the next two years.
The A380 is the largest passenger airliner in the world.
Opened in 1962 by the Duke of Edinburgh, the terminal now handles over 11 million passengers a year.
Terminal One handles international traffic and is served by Star Alliance members, scheduled airlines and charter operators.
It is also the base for Jet2.com, Monarch Airlines and Thomas Cook Airlines. The terminal has 24 stands, 18 of which have air bridges.
