Having spoken to a few FR guys the 100hr/28 days bit is hurting. With delays etc... one commented that the 60 hrs/7 days was not enabling working days off or swaps. The roster apparently shows standby cover but crew auctually unable to be called due hours. Throw in a few standard sickness, technicals and all is in a bit of a pickle. Crew control not answering calls. One guy said most of his base are refusing days off as the very long days with min rest between is proving a bit punishing. Guys gasping for their months off which are about to start again. Only rumours off course.....
