Flight operations at Delhi's Indira Gandhi International Airport faced delays today after the authorities shut one runway for repairs. Delhi International Airport Limited (DIAL) blamed "limited action/non-action" by airlines for adjusting flight schedules during the planning stage in the last four months for the runway repairs. Multiple airlines' take-offs and landings were delayed because the airport used only one runway, and repairs were happening on the other runway. An unexpected shift in wind direction also aggravated the issue.
