The Federal Aviation Administration lifted its ban on American carriers flying into and out of Ben Gurion International Airport in Tel Aviv late Wednesday night, saying it was satisfied with the security precautions Israel had taken to assure flight safety at the airport.

The F.A.A. had urged American airlines to avoid the airport on Tuesday after a missile fired from Gaza in the continuing struggle between Israel and Palestinian fighters landed near it. The agency extended the ban, originally for 24 hours, for a second day early Wednesday.

Israel strongly protested the move, which stranded thousands of travelers headed toward or trying to leave Israel, saying its airspace was well protected. El Al, Israel’s national carrier, continued flights throughout the ban.
