Do you need a visa to transit at Boston (BOS)?
Potentially yes — and this is the airport's trap. There is NO airside transit at Boston (BOS), États-Unis: every passenger clears immigration, collects their bags, re-checks them and passes security again, even to leave immediately for a third country. The country's entry conditions therefore apply in full, and without the required document the airline refuses boarding at departure.
You have 30 minutes for a journey that requires 90 at the strict minimum. No airline would sell this connection on a single ticket: it would be required to reroute you, and it knows it.
At Boston, airside connection does not exist. You clear immigration, collect your bags, re-check them and pass security again — even to leave immediately for a third country.
The official minimum connecting time database is an IATA commercial product. Our value for Boston is a curated estimate, not contractual data. The figure that counts is your airline's.
With no prediction for this specific flight, the calculation uses an average delay distribution — roughly one flight in four late, most of them barely. A flight known for being punctual, or for the opposite, will depart from this figure.
This calculation assumes two international flights on a single ticket, with no terminal change and without knowing your passport. Specify them — that is where the verdict really changes.
