When someone cuts themselves off from the world by not logging on to Facebook or checking their cell phones. Usually occurs after a breakup or a rough work week.

Derived from the cell phone setting of the same name in which incoming messages or phone calls cannot be received.

“Dan won’t answer your calls. He’s in airplane mode.”

“Sarah went into airplane mode for three days after Charlie dumped her.”

I’ve been in Airplane mode with twitter for about two months now, interuppted only by short bursts of (like they could be anything but!) tweets.
