We often bitch and complain that all the luxury and fun has been taken out of flying with the security, hidden fees and delays but we should be fair when the airlines actually do something right. Delta now gives you pajamas when you fly to and from Asia, and not just some crappy set like those terrible socks they give you, an actual decent pair.
I learned a long time ago that if you have any hope of getting a decent night sleep on a plane, you have to get out of your jeans and put on pajamas, so for me this want new or even necessary since I packed my own pair. Nobody can sleep with their balls scrunched into their five hole and a shirt that you've had on for 24 hours straight. It's really the only civilized way to travel
