How the connecting flights work?
I have booked the tickets for the connecting flight in jet airways from Baroda which arrives at Domestic terminal 1B at Mumbai and the connecting international flight for London departs from International terminal 4 of Mumbai. how to reach the domestic terminal to international terminal? and how the check in process work? I have 3 hours waiting time between these two connecting flights. Do I need to collect my baggage from the domestic airport and again check in for the international?
