Please forgive if this is the wrong thread or forum, but it seemed the most appropriate.
I'm not interested in accruing frequent flyer miles, but I do want a tool that will let me see the cheapest time to fly to a destination within a wide range of dates, like Travelocity's old feature. I tried Zuji, but it gave me a nondescript error - I think it may be aware that PDX for departures is outside of its market.
Anyways, does anyone have a suggestion for this kind of tool? Thanks!
