Once you have booked an extension, subsequent changes will be subject to an additional extension fee. We will try to complete second changes within ten (10) business days. All changes are subject to availability. If you wish to change your extension after your departure, you need to contact the airline’s office in Israel. They can inform you about availability and fees, and you would pay any fees to the airline, not to Gil Travel. Please note these would be new fees, not included in the previously paid amount to confirm the original ticket.
