I went on a long trip recently -- something around 5000 miles worth.  During this traveling I ended up at JFK, one of the LARGEST airports.  There's something like 8 terminals that are all huge and tons of people coming and going in every single direction. 

But thats not my reason for the post.  I was banking on this HUGE airport having a wireless connection ...BERNT!  wrong.  I spent about half and hour looking for one.  Turning on/off my wireless, randomly picking one and trying to get on the net.  Now, before I go further, let me specify -- FREE wireless is what I was looking for.  I managed to find one that wanted 8 bucks an hour or 25 for the whole day...I think not.  I land in Vienna hours later and guess what they have?  Free.  Wireless.  Internet.  And it works, first time.  I was happy.  By the way, Vienna is about 1/10th the size of the airport at JFK.

On my way back, I go over to JetBlue's terminal which touts free internet! free hotspot!  Not where I was sitting, and nor could the people sitting next to me.  At least they had power outlets.  (All over JFK there's "Samsung recharging stations", warning you of 2amps max with a 4amp breaker next to it ...my laptop worked fine in these outlets at full power while recharging so don't believe the 4amp hype)

Moral of the story -- if you plan on going to JFK, do NOT plan on internet connection (for free) that works ...anywhere.
