Gatwick Airport will reopen its north terminal and extend its operating hours from Monday.
The West Sussex airport announced the measures as airlines scale up their flying programmes.
EasyJet, Wizz Air and Ryanair are among the carriers whose passengers will use the north terminal from Monday.
Since April 1, Gatwick has only opened its south terminal and flights have been scheduled between 2pm and 10pm, but this will be extended to between 6am and 10pm.
In 2019, Gatwick served more destinations than any other UK airport and saw 280,700 flights and 46.6 million passengers use the international airport.
However in April this year, the airport had a total of just 305 aircraft movements, data from the Civil Aviation Authority showed.

Airlines Ryanair, TUI, EasyJet and Wizz Air are currently using Gatwick’s south terminal to fly aircrafts, with the site’s live departure board showing aircrafts departing to Mumbai, Dublin, Paris, Belfast and Sofia earlier today.
However as its north terminal prepares to open once again from June 15, airlines including Norweigian, Virgin Atlantic, British Airways, Belavia, Vueling and Blue Island are likely to restart their operations from the terminal but with fewer flights.
The coronavirus pandemic caused a collapse in demand for air travel, with airlines grounding the majority of their aircraft.
Following the outbreak, the airport said it had introduced a series of protective measures as it prepares to accommodate more flights.
These include hand sanitiser stations, protective screens, regular deep cleaning and social distancing instructions throughout its site.
Passengers will be required to wear face coverings within the airport from Monday.
Face mask vending machines will be installed, selling four masks for £3 with profits going to a local charity.
Gatwick chief executive Stewart Wingate said: ‘Having remained open throughout this pandemic, the wellbeing and safety of our passengers and everyone that works at the airport remains our top priority.
‘We have introduced a range of new social distancing and hygiene solutions to help this happen so we can all help protect each other when travelling through the airport.

‘We want people to understand that airports and air travel is a safe environment in this Covid-19 travelling world.
‘We are pleased to be in a position to reopen the north terminal and we look forward to welcoming back easyJet as they restart flights alongside our other airlines.
‘The recent Government announcement regarding the 14-day quarantine period for passengers arriving into the UK is, in our opinion, already having an impact on the start of air travel recovery.
‘We accept the Government’s absolute priority is the protection of public health, but we continue to push for regular, country by country reviews of quarantine regulations, based on medical leave application for college evidence.’
Gatwick, the UK’s second busiest airport, has been hit particularly hard by the pandemic.
It does not expect demand to return to normal levels for up to four years.
Virgin Atlantic has confirmed it will not resume flights at the airport, while British Airways is considering taking the same action.
Day two of quarantine chaos at UK airports: NOW the QR codes on top of compulsory forms ‘DON’T SCAN’ after passengers land with no idea they even had to fill one out

Passengers arriving at UK airports today described scenes of ‘pandemonium’ after the introduction of 14-day quarantine rules requiring them to fill out an online form.
Travellers told of three-hour wait times at Manchester Airport, some said the QR codes they were asked to scan did not work and others claimed ‘snotty’ border guards were saying they should have filled in the arrival form before landing.
Travellers must give their phone number and an address for self-isolation, but about half of passengers arriving at UK airports yesterday were unaware of the new policy.
Health Minister Helen Whately was asked on Sky News today how many people were placed in quarantine yesterday, but replied: ‘I don’t have the data you’re asking for.’
She added: ‘Because I’m a health minister with oversight of care homes and the NHS workforce…
There is a policy of quarantining arrivals in this country, and the reason we’re doing it is because it’s so important to us to keep infection down.’
Home Office sources said e-gates are still operational at airports but Border Force teams can decide to close these for operational reasons such as low demand.
At Manchester Airport today, Lin, 69 and Adrian Shepherd, 67, from North Wales, have flown from Sydney via Doha, Qatar.
They said: ‘It’s been horrendous. We have had no help and had snotty border police staff telling us we should have looked on the website before we landed’
Barkat Hussein, 71, and wife Nusrat Begum, 64, have spent the last four months stuck visiting family in Kashmir, Pakistan, but today returned home to Preston, Lancashire, via Islamabad.
Speaking at Manchester Airport today, Mr Hussein said: ‘The flight was only seven and half hours so luckily we were able to fill out the form before we set off’
