I am using AIRFARE.COM as they are displaying the cheapest fare for a flight from EWR to FRA.

The trip has one stop in BRU (EWR - BRU - FRA)

The first leg is on Jet Airways (EWR - BRU)

The second leg is on Lufthansa (BRU - EWR)

The layover is about 2 hours. Will my checked in luggage automatically transfer between the two carriers? I have called Airfare.com and received two different answers as well as Lufthansa. Need help please.
