What have prices looked like?

Over 25 days, 24 Sept to 18 Oct, the cheapest return we saw each day was $118 to $150.

At $166, the cheapest return found recently is above that range.

25 days is a short history, so treat this range as an early guide.

Those were the prices on those days, not today's.

Is this a good return price?

Compared with the cheapest return fare on each of 105 departure dates from 21 Oct to 13 Jul 2027, found by travelers' searches in the last 7 days (economy, the price the seller showed on Aviasales). The usual range is the middle half of those prices.
