How commuting goes across the world
 

Hello,

I would like to compare how bigger airlines (not necessarily legacy carriers) manage the commuting of their staff across the globe.
It seems that the majority of airline staff almost everywhere were not born less than one hour away from their base.
Many carriers (mainly legacy) are based in capital cities, in which many people do not want to live.

In the end I know for sure that at least in several countries in Europe, more than 50% of crews (including cabin crews) do not reside where they work.
Most of them use staff travel tickets, or extra crew member solutions, on their own airline.

At my airline, approx 60% of crew live outside of base. A system of temporary base has been put in place to take advantage of people's residence situation, but it works for only a minority of staff.
Depending on airplane sectors, the temporary base works for either 6 months, or week by week (one week of work is rostered there, without guarantee for anything else in the same month or following month)
Most people use staff travel tickets. Extra crew member boarding exists but is never a guarantee and there are only 2-3 seats per airplane, which are almost always completely overwhelmed (10-20 requests for 3 seats). There are confirmed staff tickets but it's never guaranteed that there will be enough of them (even on uncrowded airplanes), and they can be refused boarding if the airplane is full (it's more a mix between standby and confirmed then..)
Standby tickets also exist but are only useful if the plane is uncrowded.

I heard that in the US, the extra crew member system worked very easily : crews can travel for free and use all the free seats of an aircraft, is that true ?
I heard the same about Ryanair.

What's the (very approximate) percentage of commuters are your airline ?
What options are made available to them to commute ? Are there any methods put into place to help them do this commute ?
I would be particularly interested in confirmed staff tickets dedicated to going to work. If those exist are your airline please let me know.
