Last week I flew Grupo Taca's flight #441 DFW-GUA.

The FA opened all window shades before takeoff and again before landing [for safety reasons?]. [this woke up a sleeping baby near me].

Opening window shades for takeoff and landing does not make sense to me [I have even heard of airlines thiking about doing away with windows all together].

Does this rule make sense to anyone out there? Has anyone heard of other airlines with similar policies?
