It's going that way elsewhere. My outfit has published 'guidelines' regarding being 'rested for duty' to get them off the hook should an incident occur and the lawyers start asking awkward questions about whether the crew members were adequately rested. These guidelines include not more than 1 1/2 hours travel time from the airport.
So now we have commuters having to put themselves up in crappy, noisy hotels within 90 mins of the airports, and some of us having to stand our various iterations of Reserve duty in these joints.
Maybe it's not quite such a big consideration for domestic flights.
