　　Heres all the details. A 75 percent discount applies for travel on Tuesday, Wednesday, and Saturday for round-trip flights through August 18. A 50 percent discount applies to travel Monday through Thursday and Saturday if you travel round trip from August 19 through November 13. There are blackout dates to work around.
