taxied out in Zrh yesterday morning, changed to tower and was given my line up behind a swiss Rj on the other taxi way. we were number six and everyone had a clearance and new how long it would take and the aircraft they were following. No problems with it and worked really well, they were operating three runways and we were on 28 as a departures only runway with 34 departures (crossing 28) and 14 landings (independent).
In terms of GLA i`m afraid i had not noticed! but i`d rather get a line up after the next landing ***** etc as it allows me to be ready from when i`m on the runway not getting ready as i`m taxiing on to it. not a big time difference but enough to be able to be ready immediate with the power standing up as you speak to still having the last of the checks being read with a slow taxi lineup after being cleared.
Being told to line up after means you have to look and see, and find that traffic, just being told to line up may mean a quick scan of final and tcas and may miss something.
