I had booked a return travel flight from Kolkata (CCU) to Hamburg (HAM) on 31. Oct 2015 via Jet Airways. The travel plan is from Kolkata (CCU) to Mumbai (BOM) and then to Brussels (BRU) and finally to Hamburg (HAM) after a 8 hours halt. I planned the trip with a halt to meet some friends in Brussels. But now I have to travel to Stuttgart (STU) on the same day due to official work. It is not possible to travel to Stuttgart after land in Hamburg as it would be too late. Also the airline doen't allow partial cancellation of flight.
Now what I want is, to book another flight from Brussels to Stuttgart on the same day without waiting in Brussels. For this I want my baggage at the Baggage carousel. The flight from Brussels to Hamburg is operated by Brussels Airlines and I think the baggage will be transported internally by Jet Airways and not sent to the baggage carousel.
What should I do, or where should I inform to get my baggage at the carousel in Brussels even though I have a connecting flight.
