It is also the cheapest one-way we hold, of any age.

What have prices looked like?

Over 49 days, 24 Sept to 11 Nov, the cheapest one-way we saw each day was $40 to $84.

At $40, the cheapest one-way found recently is at the low end of that range.

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

Is this a good one-way price?

Compared with the cheapest one-way fare on each of 26 departure dates from 13 Nov to 6 Oct 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.

No. We hold one-way fares on 1 other departure date within 3 days of 19 Nov, and it is not cheaper.
