Is there not just a hint of naivety about this thread ?
Where your first base is will probably bear little resemblance to where you end up throughout your career with an airline. Some of the lo cost boys have relocation agreements which cost them (the company) NOTHING to re-base a pilot. Expect much movement, especially in the years to come, as our status and "union power (what's that ?)" decline.
As for "which bases do airport standby?" -- this ignores, or shows a lack of awareness, of the constantly shifting nature of the business. What applies today will change many times in the future.
I take your point that, by initially establishing yourself at the base of your choice, you're doing the best you can, but don't expect it to last !
