New tool in booking engine at WJ.com
 

Looks like they finally (FINALLY!) caught on to how useful the "flexible" alternate dates bar on the Air Canada booking engine is - just saw this AM that Westjet has a "other dates" scroll bar at the top of the engine; it includes the lowest fare over the next 28 days. Good work Westjet - too bad it took you over two years to realize how useful it is!

Better late than never.

Unfortunately it isn't entired accurate.. I was looking around last week for some flights and whenever I clicked on the cheaper day the fare readjusted to some higher price.

Hopefully this is just a kink they are working out because it really isn't a useful search tool if the price isn't correct.
