7/28 looks to be the revised target date for meals with a limited rollout (SEA/SFO/LAX/SLC). No meals listed to/from DEN/PDX/LAS/PHX/TUS/SMF/SAN/SNA/MIA/ANC/FAI among others on 7/28 even on flights over 1500 miles. Target start dates for these other stations look to be 8/17 and 8/24.

Also, hub-to-hub/focus city routes over 900 miles showing meals during meal times starting 8/24 (MSP-SEA/SLC/RDU/ATL/BOS/LGA/JFK, DTW-AUS/SLC, ATL-MSP/BOS/MEX, RDU-AUS, etc). Although AUS-MSP flights currently have empty Meal Services field.

Searching further out, it looks like old meal service standards are restored on 8/31 with all flights between 900-1500 miles getting meals during meal windows.
