From another point of view.
Warsaw airport is getting more busy, so we observe different responses to our commands.
We've started using 2 RWY for dep, single for arrival (we have no parallel rwy, just the crossing).
See: most of the time we are using one rwy (29) for deps, another (33) for arr. What concerns pilots is, when the line-up is given for rwy 29, and the clrd to land rwy 33 was given before. There's much more concern with that situation (different rwys !), than during situtation, when RWY 33 is used for both deps and arrs, and rwy 29 is used for departures only, and "line-up behind arriving" was issued.
