US airlines shunned the Zionist entity for a second day on Wednesday, pending a decision in Washington on whether to lift a ban on all US flights there due to the Gaza conflict.

Delta said its flights from New York's John F. Kennedy airport to Ben Gurion International would remain suspended until further notice.

"We plan these things conservatively," Delta's chief executive Richard Anderson told the CNBC business news cable channel.

"But we will need concrete information from our government that lets us draw an independent conclusion ... that it's going to be safe for our passengers an our employees."

United Airlines told AFP "our flights remain suspended until further notice" although its online timetable indicated two flights out of Newark later Wednesday as being "on schedule."

US Airways, meanwhile, said it hoped to resume its service from Philadelphia on Thursday, subject to approval from the Federal Aviation Administration (FAA).

"We are reaching out to customers and working with other airlines to re-accommodate those affected," a spokeswoman added.
