How has Israel’s commercial airspace stayed available?

.BECAUSE THE bloody assault on Israel on October 7th, about 90% of airlines flighting to Israel, consisting of British Airways and also Emirates, have suspended air travels to the country. Hamas, the militant team that works the Gaza Strip, has actually repeatedly terminated rockets at Ben-Gurion airport, Israel’s most extensive, near Tel Aviv. On Oct 9th one landed not far away, sending travellers scrambling for cover.

Yet Israeli airport terminals, including Ben-Gurion, remain to work. Why as well as how possess they remained open?
