We are flying Sunday and Monday to London and to dulles on the two days. Possible to check luggage through from Brussels-Heathrow AND Hearhrow-Dulles? We are riled of our bags!
If it is one ticket you can check bags through to the end destination. But if two tickets, NO. Sounds like you should have fewer bags for the next trip.
That fact the the flights are separately ticketed does not necessarily mean you can't check bags through. There is a good chance that the airlines will have a baggage agreement that allows you do it. I have on a number of occasions. Be sure to ask when you check in for the first flight and have you ticket for the second flight so they can get the information they need.
