If these are bad guys, considering how Bloombug hates profiling, JFK and NYC were probably a safer choice.
My point exactly. Flying into JFK is good if you want to have some bogus excuses about not making your flight, or if you wanted to blend in (easier in NYC than Denver). Claiming that you had trouble on your connection gives the bad guys some 36 to 48 hours of lead time, before anyone notices they're gone.
