I have a trip to Croatia planned for the end of September. I fly JFK to LHR on VS4, arriving at 07:10 at Terminal 3. I then fly from LHR to Rijeka on Croatian Airlines flight OU 491, leaving London at 11:50 from Terminal 2. My understanding is that I can check my baggage right through to Croatia from New York. Do you think I would be wise to do that? I'm unfamiliar with both Croatian Airlines and the transfer from Terminal 3 to Terminal 2.

Any advice would be appreciated.

Thanks.
