Delta Air Lines is apologizing for napkins that some fliers thought were creepy. On one side, the Diet Coke drink napkins featured the words "because you're on a plane full of interesting people and hey ... you never know." On the other side it instructed passengers to "be a little old school, write down your number and give it to your plane crush" and included spaces for the person's name and number. Delta is removing the napkins and apologized if they offended anyone.
