I've used the arrival service last few times... the first time was so worth it as the lines were at the top of the ramp... last couple times it probably saved me minimal time... I think it's well worth it as many of us book our trips so far out... flightstats and similar websites only have a 3 day window so therefore it's tough to judge... my personal experience is the earlier the arrival, the better...if I don't land before noon at MBJ then I'll continue to purchase it to be safe... like others, I'm not so big on the departure Club MoBay... I wanna get to Negril and stay as long as humanly possible
