I see a flight available online, but I was told there was no availability or the price is higher than the base rate. Why?

Birthright Israel group tickets are subject to specific terms and conditions. They are NOT the same as publicly offered tickets.  There may be cases where a flight is available to the public that does not meet the requirements to be offered as part of the Birthright Israel program. In some cases, the same class of service as the group fare may not be available for the requested extension, and the airline may offer a higher fare to confirm the requested return flight. We always do everything possible to accommodate each request, and will provide you with the best options available.
