This was what Israel was facing before this ban was rescinded.
As the article says, its a score for Hamas, and thats unfortunate, but these airlines were canceling flights on their own, even before the FAA ever uttered a word.

On Tuesday, four major U.S. airline carriers announced their decision to cancel flights heading to Israel indefinitely, one specifically citing the danger of Gaza rocket attacks near Israels Ben Gurion airport.
Shortly afterwards, the Federal Aviation Administration (FAA) said it told all U.S. airlines that flights to the airport are prohibited for 24 hours, according to The Associated Press.
Maybe Israel should make an example out of one of those airlines and ban them for a while
