Stuck on ground in plane at ORD, just got an update that the "mainframes" are starting to come back online.

EDIT: We're now about to take off.

While in this case they probably are actual mainframes, at my firm we use the term to refer to the VMs running in tiny boxes that replaced what once were also mainframes.

Sometimes the language outlives the hardware.

Uh, they aren't using mainframes.

10:1, Linux fail.

They most certainly are. The primary systems running all the major US airlines are all mainframe at least in part.
