Well I dunno.
Altho I have never worked for so called low cost carriers, have several friends who do...specifically Southwest.
They certainly seem satisfied...good pay, nice rosters, a company who treats 'em quite well...sounds like a pilots' dream.
Perhaps it is.
'Course they have so called 'long haul' as well...nearly 5 hours coast to coast.
Not the 12+ that is more the norm in other carriers, time zones a plenty, shorter nightstops, downgraded hotels (in some cases)...but hey, still not a bad job at all.
After 38+ years, would I do it again?
You bet...a most satisfying way to make a living.
