not at all, then again if you dont want to fly and cant think of a reason why , now you got it. Really not that bad Ive shown up an hour before at EWR and no problems. However, I always check to see how full the plane is, there is a large # of both No-Shows and Stand-Bys. So if you play it too close (even 1 hr) you just might find that your seat was given away, and theres no room left for you. The same out of TLV.
