Through checking bags on BA1 - Do you have to collect and re-check?

Every day, BA flies about a dozen flights from London to Terminal 7 in New York's JFK airport. London Heathrow doesn't offer US pre-clearance, and based on lengthy discussions on flyertalk, won't be able to offer it any time soon either. London City doesn't have pre-clearance.

One quirk though is BA1. The BA 318s from London City can cross the atlantic on a full tank, but can't take off from LCY fully fueled, so stop off in Shannon in Ireland. BA3 rocks up in Shannon after the CBP staff have clocked off for the day, but BA1 normally makes it in time for passengers to undergo pre-clearance while the plane re-fuels. As such, passengers on BA1 normally arrive in the USA pre-cleared, don't need to go through immigration on arrival, and don't need to collect their luggage + clear customs on arrival.

My understanding is that most people on the "BA Babybus" LCY-JFK services travel hand luggage only, and also don't connect. People with checked luggage are therefore unusual on the service, and people connecting with luggage even more so.

For the odd unusual person flying LCY-JFK-(elsewhere), with checked luggage, on BA1, what's the luggage transfer situation in New York? Is through-tagged luggage automatically transferred? Or do you still need to collect your luggage on arrival into JFK (though in the domestic collections area), then re-check it for onwards travel?

Do you have to pay to check a bag twice?

Baggage fees are per bag and per direction. So one way = one charge. Round trip = two charges. If your flight has a connection, bags will generally transfer from flight to flight and no additional fees will apply.

Do you have to recheck baggage on connecting flights?

If your flights were booked under one ticket, your bags will be checked through to your final destination. If your flights were booked under separate tickets, you will need to collect your bags and recheck them before your connecting flight.

What does it mean to through check a bag?

To request that one's luggage be sent to one's final destination, as when traveling through multiple cities or via different modes of transportation. I don't have any bags with me because I checked my luggage through to Rome.

Do I have to go through security again for connecting flight?

For connecting domestic flights, you almost never have to exit and reenter security, though there are some exceptions at airports where the terminals aren't all connected. For domestic-to-international connection, it's still pretty rare that you have to exit and reenter security, even if you're changing terminals.
