How has Israel’s business airspace remained open?

.GIVEN THAT THE bloody attack on Israel on Oct 7th, about 90% of airlines flighting to Israel, including British Airways as well as Emirates, have actually suspended trips to the country. Hamas, the militant team that runs the Gaza Bit, has continuously axed rockets at Ben-Gurion airport, Israel’s largest, near Tel Aviv. On October 9th one landed not far away, sending out visitors competing cover.

However Israeli airports, including Ben-Gurion, remain to function. Why and how possess they kept open?
