WHAT TO TRY

Three small changes with three different effects.

Allow one connection

Rome changes from €145 to €119. The direct fare still passes the other conditions, but the cheaper connected fare becomes the displayed option. €26 saved does not automatically mean a better journey.

Raise the ceiling to €220

Barcelona becomes eligible only if you also allow one stop. Changing the price ceiling alone cannot overcome the direct-flight rule.

Widen the stay to eight days

Lisbon can join the result list at the original €180 ceiling. A watch that stays silent may have a duration problem rather than a budget problem.

The horizon includes the current calendar month. Three months from the scenario date means October, November and December, not a rolling 90-day window. The production search additionally uses provider availability and expiration information absent from this training set.
