the only real/official one is laufer vip. in the most popular version, they pick you up where you get off the plane, take you downstairs right there with the elevator, drive you (outside) to passport control, whisk you through (no line) papport control, pick up your duty free, and pick off your luggage from the belt. the price is $105 total for up to 4 people (5 to 10 - $12 per person) . ive used it in the past when i came with a new baby and it was very convenient. they carried our hand bags, we didnt have to walk anything, and didnt have to wait for passport control. at the time i also added transportation to jerusalem so they took my luggage off the belt and loaded up the car.
