Thank you!

The girlfriend - a student - is going to a conference. I want to watch for better fares than currently listed on AC. I really don't know how to interpret the table given.

i.e. the first line, L30UCTG AC L Round-Trip 278.82 (USD) E 04/29/18 07/12/18

... does that imply a fare that will go on sale 4/29?
