Forgot to add there is no "free" travel except for one's Annual Leave Ticket. Plus if you are commuting to LHR you will be paying the airport taxes. No jump seat. Might get a bit expensive if you plan to go back and forth a few times a month. Commuting is just something that is extremely difficult or close to impossible. If one has too many days off there will be inserted an Available Day into the roster. Doesn't matter the hours you fly, it is more like days of work. Just my 2 dirhams.
