I have made the trip from Dallas to Tel Aviv several times over the past year. From Dallas to Tel Aviv it is about 14 hours flying. I have gone from Dallas to Atlanta to Tel Aviv on Delta, and also Lufthansa, from Dallas to Frankfurt to Tel Aviv.
The air distance from Frankfurt, Germany, to Tel Aviv, Israel, is 1,827 miles. That equals 2,940 kilometers or 1,587 nautical miles.
