The reservation system of India's largest airline IndiGo was restored on Friday, hours after it faced intermittent issues that prevented people from making ticket bookings for a second time this week.
The repeated glitches are an early headache for CEO Willie Walsh, who took charge on August 3, less than five months after his predecessor Pieter Elbers resigned following scrutiny over a major operational breakdown at the airline.
Earlier on Friday, IndiGo's website displayed an advisory identical to one it issued on Wednesday, citing "intermittent issues" with its core reservation platform.
It was not immediately clear whether the problems were linked to Wednesday's disruption or whether the earlier issue had been fully resolved.
IndiGo did not respond to an email seeking more details.
Reuters journalists in four cities were unable to book tickets through the website, which displayed a "no data available" message when they searched for flights, while some were also unable to log in to the app.
Multiple users complained on IndiGo's X handle on Friday about failed bookings, problems completing web check-ins and payment confirmations.
IndiGo came under scrutiny last December after pilot rostering problems forced it to cancel around 4,500 flights, leaving tens of thousands of passengers stranded and disrupting travel across the country.
The airline held a 67 per cent share of India's domestic aviation market in July.
