Every way across

One row per operator and speed. Where a service is sold as fast and its average does not clear 45 km/h, the word appears in quotation marks — the boat is fast craft, the crossing is not.

Where else these quays go

Which months this runs

Season not heldwe can say when we looked, not which months run

Our records for the Chicago–San Antonio crossing were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.

If you are travelling well outside August 2026, confirm with the operator before you plan around it.

What we do not know

No fares. The choice between AirTran Airways at 2 h 35 and American Airlines at 2 h 36 is mostly a price decision, and we hold no prices for either.

No departure times. No rate is held for this pair either, so we cannot say how often it runs.
