Port Moresby runs 7 hours ahead of Sofia. Travelling east is the harder direction to adjust to, so if the trip is short, an early departure that lands in daylight is worth more than a marginally cheaper overnight.
We publish observed fares for this route when we have them, and say nothing when we do not — there is no estimate on this page. What holds regardless of the route:
Midweek departures are consistently cheaper than Friday and Sunday on most routes, because that is where demand sits rather than because of any pricing trick. Where we have observed fares for Sofia–Port Moresby, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
