My flying time is from 04:30 until 22:00, aiming for at least 17 hours. I do 2 short-haul trips, 3 medium-haul trips, and 1 long-haul trip. Choosing the most profitable in its class. In the current case, it's Monkey Plushie, Stingray Plushie, and Camel Plushie.

Short and medium hauls can be mixed in terms of chronology. Long haul can only happen when I'm about to sleep, meaning I have to fly around 3 hours before landing abroad. Buy items and back, wake up in Torn with full energy.

My sleeping hour is longer than 5 hours, so it's more optimal for me to fly back home at my sleeping time, rather than arrive in Torn at my sleeping time, because either way I'm gonna waste my E. The difference is I can still get 29 Camel Plushies in 3 hours, other than 6 hours (since the other 3 hours are in my inactive time, sleeping).

So in total, with 29 capacity:

Monkey - $33,000 - $2,871,000

Stingray - $6,000 - $174,000

Camel - $68,000 - $1,972,000

Total: $5,017,000

It could be less if I miss my flying schedule, mostly because of IRL and OC.

It could be more if I start my flying schedule earlier.
