It' s not just travel expenses. It's all expenses for tourists while they are in Israel. The tourism industry devoloped in earnest in Israel in the 1960's and 70's when you had to be quite rich to travel at all. Fancy hotels and overpriced restaurants were built. Since then the industry somehow has remained believing that this is the demographic. Of the uncountable new projects building new hotels, there are almost no cheap hotels.
