How has Israel’s commercial airspace remained available?

.GIVEN THAT THE grisly attack on Israel on Oct 7th, approximately 90% of airline companies taking flight to Israel, including British Airways as well as Emirates, have suspended air travels to the country. Hamas, the militant group that runs the Gaza Bit, has frequently fired rockets at Ben-Gurion airport terminal, Israel’s biggest, near Tel Aviv. On October 9th one landed not far away, sending visitors rivaling cover.

Yet Israeli flight terminals, including Ben-Gurion, remain to run. Why as well as just how have they kept open?
