Bangkok’s Suvarnabhumi Airport has completed its first phase of repairs to the airport’s eastern runway, returning operations to normal, officials said.

The airport, Thailand’s main gateway, is working through a maintenance program for its eastern runway that began June 11. However, well-reported problems with cracks on parts of the runway and a power outage that delayed some flights and disrupted others raised concerns.

“Testing to ensure total safety standard compliance has been carried out and the runway has resumed operations,” Airports of Thailand (AOT) president Anirut Thanomkulbutra said at a press conference. “All aircraft types, except the Airbus A380, can now take-off and land on the east runway—making it virtually back to normal, full operations.”
