Thailand will restrict the number of incoming flights as they are overloading its skies and airports, Transport Minister Prajin Juntong said on Friday. The minister said the move away from the “open sky” policy was needed to ensure aviation safety. Staff were now working on the full details.”Our sky cannot provide space for more flights. To ensure safety and prevent aircraft collisions, we must limit the use of our sky, manage flight schedules and re-organise flights to times of light traffic to prevent congestion in some periods. The problem must be solved quickly,” ACM Prajin said.
