Hoping someone will be able to help as I’ve googled a lot and still not clear on how our flights operate for a USA holiday next year.
On our return journey, we are flying from Miami to JFK with American Airlines then stop over at JFK for four hours, then flight to UK with Finnair (operated by BA), do we have to go through immigration at JFK on the flight from Miami?
Also, assuming we will need to collect our luggage at JFK and check in again for flight to UK as different airlines?
We booked via Expedia, and Bizarrely, the Finnair app seems to hold all the flight details, even the flight out which is BA, whereas the BA app only shows the flight out with them so totally confused.
Can you tell I’m not a seasoned traveller!
