If you can survive all those long haul in a row, then... you can go to Tahiti for relatively cheap.
Prices start at 1273€ for a RT between HEL and PPT but I'd recommend you flying from ARN instead to get SQ A350 and NZ 787 both ways for obvious comfort reasons !
haven't calculated yet how much it earns but if you are interested in seeing Tahiti and a *A status, then this is for you.
Because the destination is far away, minimum stay of just 2 days but take into account hotels are expensive in PPT, it is an exclusive destination.
Few seats in March, April, June or even July
From HEL 1273€
