International flights are lonely times folks. You sit there, perhaps look outside the empty window if you're lucky enough to get the seat, and try to make awkward conversations with your seating mate. Luckily, if you're flying through Delta Airlines, you've brought your laptop and use their nifty in-flight Wi-Fi service, but dude, you gotta behave yourself.
Delta said that it will filter their in-flight Wi-Fi service when it launches later this year "to block inappropriate Web sites"--yes, pr0n will not be tolerated when seated next to a stranger while flying thousands of feet above ground. Previously, the airline mentioned that flight attendants were in charge of handling such situations, but to assure everyone's safety and discpline, they're just simply saying "No" to any potential gross behaviors.
Just pop-in a sleeping pill or two and you'll be fine.
