KLM is following, I just hear from a Dutch-Israeli friend.
Just checked the Amsterdam Schiphol airport departures for Friday and while the KLM website doesn’t mention anything, these flights (scheduled in 21 hours from now) already show as ‘delayed’:
09:15 Tel Aviv LY 338 El Al Israel Airlines Expected Details
20:50 Tel Aviv DL 9575 Delta Air Lines Delayed Details
20:50 Tel Aviv KL 0461 KLM Royal Dutch Airlines Delayed Details
