It's a sale!
TICKETS MUST BE ISSUED ON/AFTER 29MAY13 AND ON/BEFORE 06JUN13.
It looks like the seasons are 1 October to 15 December 2013 for L season (lowest fares), and 19 April to 23 June 2013 and 18 August to 30 September 2013 for K season.
This is specifically for SFO, and I haven't yet looked to see how wide this sale is.
