Yea, I think I'll skip this time also. If it was FT'ers only then sure, but I am already getting a random seat mate so I don't really need a tool help me hook up to another random seat mate before the flight.
And also, this would mean that one of the people have to get the middle seat if it's in Y and who wants to volunteer for that
The idea is good though, if you are the kind of fellah that likee to talk all the time in-flight - should promote this in the US
