Good morning.
First suggestion is some searching because a lot of answers will already exist on this site in various places - I know because I've provided plenty of them.
More specifically, there is less standby than you think. I'm guessing you're in a more seasonally skewed airline, as I was years ago in JMC where winters were very quiet. DHK works throughout the year. Having been a mainly SH airline with a bit of LH bolted on we are now fundamentally a LH airline with a small rump of SH for which we are not recruiting. Westbound trips about four days, Eastbound are longer possibly up to 12 days followed by days off of varying numbers. There is no set roster pattern so don't apply if you are averse to change. Contractual days off inc leave is 162pa so if you feel you've been shafted by a short break it has to even out in the end.
