I think you replied to the wrong parent? Can't see anyone talking about class action lawsuits. Anyway, considering the stringency of aviation regulations designed to mitigate already very small risks, I think it would be consistent to force passengers to get up and have a walk once in a while (if this would indeed mitigate the risk of DVT). Obviously airlines would never take this step, but they could at least recommend it, or the FAA could enforce it.
