Link 2 bookings to enable checking luggage through?
I'm looking at a LHR-JFK flight in business and was thinking of an ex-EU fare then I stumbled upon flying via MAD (AA or IB) without needing a positioning flight to come back to LHR.
I would have to buy the LHR-MAD separately to the MAD-JFK sectors as its much cheaper that way.
Now once booked would I be able to link the bookings and then check the baggage all the way through...
...or would I need to collect my baggage in MAD and check in again?
