I have commuted for the last 19 years. The hub my Airline fly's out of has some of the most expensive real estate in the world and a commensurate cost of living.
No salary adjustment is made for this and yet there is one in one of our much smaller hubs in the Pacific. For myself on a single income it is prohibitively expensive.
As far as commuting and fatigue are concerned, not a factor for me, flying almost exclusively long haul with evening departures I take the first flight up from home in the morning, on arrival I have lunch then take a long snooze in our rest area all afternoon showing up well rested for departure.
Unlike many of our locally living Pilots who often show up tired after battling rush hour traffic and or dealing with issues at home all day.
In fact I don't know any of our commuting Pilots who are not equally conscientous.
411a, as usual, in matters other than the L1011 has it completely wrong.
