DL 112:
5/24 - 2 blocked and 1 empty
5/25 - No DL flight showing - just AZ
5/26 - 2 blocked
5/27- 2 blocked 2 empty
5/28 - 2 blocked and 2 open
In all cases 1A and 2A are blocked. They won't both be for crew rest so you will likely get one of those.
Side note - really odd that DL and AZ are operating the same route at the same time several days a week.
