Very few airlines offer a commuting contract now. Saudia itself used only to offer expatriate contracts with fairly relaxed, (but no alcohol), accommodation in expatriate enclosed compounds/villages. Saudia also allowed crew to put them selves on a crew dec. when starting days off. Travel to and from destination in uniform, pilots responsibility to make sure they were back in time for next duty. Singapore tried basings but dumped it as soon as they could, accounts wanted it but operations didn't. Didn't allow for a stabilized and fair captains roster, among other things.
