Best connections that day, one ticket

Most reliable Quickest (80%+ on time)

Ranked by chance you reach Sacramento on time, from each leg’s forecast for the day. Total trip = scheduled departure to arrival (Sacramento is 2 h behind St Louis). Layovers up to 4 hours. Pick a connection for its 12-month details.

No one-ticket connection fits with layovers up to 4 hours that day. Try any airlines.

How these are worked out. Each flight’s odds are our forecast for that day; flights of airlines we don’t forecast yet use their 12-month record and are marked. Makes the connection: the first flight’s 12-month lateness curve, scaled so its chance of arriving 15+ min late matches the day’s forecast, at the layover minus the 45-minute minimum (90 on separate tickets). Arrives on time: first flight not cancelled × connection made × second flight not cancelled × second flight within 15 minutes, each from the day’s forecast.
