Just a brainfart but maybe more (certainly the bigger ones) airlines should rethink how to make best use of its pilot pool.
With today's level of automation and therefore the possibility to set up the cockpit of different sized aircraft from 1 supplier in a similar matter, aka cockpit commonality, it might not be a bad idea to make better use of these characteristics.
Long-haul pilots could be used to operate in the short-haul fleet on a regular base (eg 25% of their time) giving them ample opportunities to do a lot more T/O's and Landings and also operate into the smaller airports with more demanding conditions lower CAT runways, more basic navigation, etc... .
Today this commonality feature is not used to its full potential, FO's with too few hours land to quick in the RHS of a Long-haul wide-body, experienced long-haul pilots have to spend too much time in a perpetual state of jet lag, with too few extended breaks to be able to recuperate.
It's not going to solve every single issue because many companies operate a mixed fleet making it virtually impossible to hop from short-haul to long-haul but for many companies this could actually work.
I realize that for some pilots this sounds a lot like swearing in church (pay-rates and privileges) but if you think of it , it might not be a bad idea to be home more sometimes, and long haul careers could be started up more gradually for the youngest and least experienced FO's.
Not saying that this is the reason the 777 crashed, we won't really know what happened and why it happened until the final rapport comes out, I was just expanding on some of the comments in this thread.
