I plan to arrive on an international flight to Newark and will have 8-9 hours in between another international flight on the same airline departing from Newark Airport.
If I checked-through my bag at the original embarkation point for my first flight, can I check in an additional luggage at Newark later for my second flight? That is, I will pick up my luggage at Newark after my first flight, then hand to the transfer desk as a check-through luggage, then go out the airport, and then come back with another bag and check-in for my second flight. This means I will collect two bags at the final destination.
Would the airline allow it?
