PaxBoy: the dispatcher is responsible for creating a legal flight plan and the captain is responsible for assuring it is really legal---if for some reason the captain decides to take more fuel--[not always 'just for comfort'-but due other operational considerations] then NO one should question it---
Captains're mad at dispatcher---- for not realizing that the frequent delays at xxx airport due to xxx factor[s]---being legally responsible --- he doesn't want to or have to justify every pound of fuel he want to take over minimum--but in the interest of CRM he
should share why with dispatch so that THEY LEARN---
Dispatchers're mad at the captain ----because he's gone through intensive training actually a little more involved in certain areas of theory than the atpl knowledge and practical test standards [a few more advisory circulars and topics] and the training is intense and very involved- so they do want their specialized bodies of knowledge respected by the captains---
and the two sides can't seem to see the others troubles---
