A massive airspace closure has built up over the past few hours over Pakistan and North India, which is affecting air travel as I write this. Earlier today, at 7:30 UTC, a NOTAM was issued by Pakistan, closing out Pakistan Airspace to all air travel.
Pakistan Airspace Closure
Here is the screen grab of the NOTAM issued by Pakistan, on both their airspace divisions. The Airspace Closure is currently valid till February 28, which is tomorrow.
Earlier than this, the Pakistan Airspace was only available above 32K feet, with the expectation of military action under that flight level. At no point of time were only Indian aircraft barred from flying over Pakistan as per current information. A Singapore Airlines A380 flying to London was turned away as well, for instance, so it flew over the Arabian Sea instead.
Indian Airports shut down & resume operations
Following the military action this morning and the closure of the Pakistani Airspace, India had shut down, temporarily operations at six airports north of Delhi. Here is the NOTAM.
The following airports are affected:
And as I write this, the NOTAM has been vacated as well, and flights are back up in the air from Jammu, for instance.
In the meanwhile, the Pakistan Airspace looks like this at the moment.
