For Ryanair on any typical week you tend to actually fly 3-4 of your 5 days on, either one or two days on will be on standby for 12 hours. On a week where you are doing early shift the early standby runs from 5am to 5pm. On lates it goes from 1030 to 2230. This means that you only fly 3-4 days out of the 9 in the pattern.
