Virgin Australia will resume services to Vanuatu's capital on Sunday, after the runway in Port Vila was given the all-clear by the airline's experts.
Services were suspended suddenly on Monday after a gap opened in the runway, only three months after repairs were completed.
In January, Air New Zealand, Qantas and Virgin Australia suspended their services over concerns about the safety of the runway.
The announcement saw the country's new government scramble to re-negotiate a World Bank loan to carry out emergency repairs which were completed in April.
Those repairs were supposed to last for as long as a year while the government sought a more permanent solution.
In a statement, Virgin says it has inspected the runway again and is happy to resume services, although if it deteriorates again services will be suspended.
Virgin is the only airline to have returned to Vanuatu since the repairs were completed.
