Fare Desk notes

Today's fare for the Boston to Vancouver route sits at €119. Our verdict is “Wait,” as this price is cheaper than 7% of the fares we logged, while the typical fare sits at €101 and the lowest fare we have seen is €79.

Our data indicate that September is the cheapest month, with a typical price of €82 based on 11 observations. Booking 14 to 27 days before departure usually yields a typical fare of €97, which saves €17 compared with last-minute pricing. The current offer is from WestJet at €119, while Air Canada is listed at €143.

For the opposite direction, the return fare today is €158, close to the typical €160, underscoring that both legs are priced higher than the historic lows. Given the available data, waiting for a later date or targeting a September departure would likely produce a better price.
