What works
The diagram assumes a number of user groups – parents of youngsters, sleepers, long-leggers – in addition to universal concerns like not dying in a crash or understanding that your appendages are more likely to be run over by the beverage cart if you’re seated on the aisle. Friend of mine broke a foot that way so I’d say it’s a non-trivial concern and lends support to the choice of the bulkhead rather than an aisle seat for those with long legs.
What needs work
This blog needs work. I haven’t posted any non-standard graphics lately. Boring. Even though this has nothing to do with sociology, it’s a necessary inclusion.
