I'll have 2.5ish hour layover before F A380 ride to JFK this summer. Want to ask how soon I should leave lounge to head toward preclearance (I have global entry) due to the fact that I will need to check my laptop ?
I assume 65-75 mins before takeoff will be ok? Still provide 3 different choices for free cigars (still debating if I should eat before flight or stick to cigar session..

)
