Evening PPRUNE,
Ive noticed on alot of flightplans that US carriers such as Continental, Delta and AA dont use the default MIRSI or DAYNE STARs when they arrive from the North or West, also they go DCT to NOKIN when using a SID also instead of following the actual SID
if you look at the AA flightplan below you will see that AA went DCT from DUB VOR via LYNAS waypoint straight into MAN...

So why do US carriers not use the default SIDS/STARS, is it too reduce flight time, what?
would like to hear an good PPRUNE explanation
i know you guys are capable
