IsraelontheHouse does not organize any flight bookings and changes in-house. All flight extensions PRIOR to your departure are handled by Gil Travel. All flight extensions once in Israel are handled directly by the airline unless otherwise stipulated in the Airline Guidelines.
Please note that there are costs involved in extending your flight, which vary from airline to airline. It is also subject to availability and the terms of your specific airline. When possible, please try to make your arrangements early to avoid disappointment.
