At OO we have trips that are:
1. 4 days long (My favorite...)
2. 3 days long
3. 2 days long
4. 1 day long (aka local)
5. Standups, these trips are the last flight out at night and the first one back in the morning. Usually they pay really well, but they in-fridge on your sleeping pattern. Usually you will do 3-5 in a row and by the end you turn pumpkin...

If you are a single parent you could do locals, drop kid of at school and then fly for 4-6 hours and pick the kid up, as long as you have a plan if you get stuck...
And standups, you will go to work around 8pm and be back home around 7am
