> Travel may be booked online using a GoPack up to 90 minutes prior to scheduled departure, subject to flight availability and all booking window and travel window restrictions.
How much would a flight 90 mins before departure normally cost?
They're going after a different customer compared to someone who books weeks/months in advance to get a super cheap fare.
So the Gopack is cheaper (~$1176 [I'm sure the $196 fluctuates, but it seems to be on the high end in my limited googling] vs $739), but after taking into account that you have to use all the codes up within 3 months or lose them and there is an extensive black-out range even within that 3 month window, I'm hard pressed to recognize the ~$437 savings as being worth it for all but the most niche needs.
YMMV on the other routes, maybe they are better values.
From Jetblue's fine print:
You can use your GoPack to book online as soon as you receive your codes (approximately 24 hours after purchase) until 6/17/14 for travel through 6/17/14 (blackout dates 4/11/14 - 4/28/14).
