Yesterday on a 763 from SEA-ATL there were no Dasani water bottles waiting for FC passengers. This is the first time I've never seen them on the armrests before boarding.
Pre-flight drinks were offered, though. And if you asked for water you got the water bottle.
There's only one flight where pre-flight drinks weren't offered and that was due to late catering. Otherwise I'm running at 100%.
