I'm resisting the urge to go full on parental on this post, so I'm going to leave it at this ->
Taking children anywhere is an extremely stressful situation, beyond what an average childless person could possibly understand. Since we as parents don't like the idea of been locked away in our houses for 18 years lest we upset someone else in society we do like to try and experience life events much like childless people do.
Why should society provide just that little bit more support to a family than a childless person? Because children are difficult, they don't understand what is happening around them, and they have no concept of time. In this instance this family only started asking for a little comfort AFTER VA failed to deliver a flight on time as promised.
