The above is part of reason AFAIK, Karachi airport has now re-opened (it is southern enough etc). Pakistani OSINT friend I trust tells me most other airports (to the north in Pakistan) are closed.
India also has closed a large number of airports in North India for a few days:
Following a ceasefire with Pakistan, 32 airports in northern India have reopened, with airlines like IndiGo and SpiceJet resuming services and offering rebooking support.

Majority of other regions of India nothing has changed in comparison.
Other than that iirc for Indian side:
- All schools, colleges, unis have been closed in (Indian) Punjab state indefinitely
- New Delhi railway station, Connaught place and India Gate have been "cleared out" (as some kind of precaution for some threat on ground detected it is speculated...but unknown at this point).
