Inability to have a crew blamed on weather, it a gray area to me, especially when the effects are felt for days. I understand that the initial effects of the crews out of position are weather related, but B6 seems to recover from it worse than others. And since they can continue to blame it on weather and there is nothing stopping them, they seem to do so. I do not think that JetBlue is alone in this, but it is something that is frustrating when it happens.
