This is quoted from the Terms and Conditions :

With the Flex - four-day option, bookings are permitted on Tuesdays, Wednesdays, Thursdays and Saturdays only,

I'm looking at possibly buying a flight pass for this year, and although I'd love to go with the latitude option, I have a hard time justifying the extra $$. However, I'm a little confused as to whether or not there is a four day option you can buy that is cheaper or if the Flex fare flight pass is only for flights operated on those Tue-Wed-Thu-Sat ?

I did a search here and couldn't find anything so I figured someone here could probably point me in the right direction.

As always, thank you in advance.
