[QUOTE=Princess Jessie;9278260]I will be travelling to the Maldives via Mumbai... it is a bit of a trek as we are travelling BA to Mumbai then UL (Sri Lankan) from Mumbai to Colombo and on to Male..

Welcome to FT. I just got back from the Maldives a couple of months ago, and I'm sure you'll enjoy it very much. Amazing waters...

You'll need to go through the whole immigration/baggage claim/check-in again/security protocol.

When you finish with customs and get past the officer who collects the last bit of paper from you (at the bottom of the immigration form), ask for an elevator to take you to departures level. In the past, I had to go outside, and walk towards the end of the terminal, and go up a couple of flights of stairs b/c the elevator was not working.
The elevators are not readily apparent. There is one somewhere in the bowels of the airport, just inside the hall where the taxi/hotel 'stalls' are located.
Also, if you do find the elevator, you'll have to ask someone which button to push. They just had numbers, without any explanation of which level corresponds to departures. It's not very obvious that you have reached the correct floor, since the elevator is in an out-of-the way area; you don't really "see" the departures hall. There are several floors of offices above the airport, and non-airport people are not allowed in some of those areas, as I found out.
Finally, I don't recall if UL and BA use the same side of the terminal. If not, you could have a nice long walk to the opposite end of the terminal. Do this walk on the departures level. It's a bit more open. On the arrivals level, crossing from one end of the terminal to the other there are some areas that can be quite isolated.

Good luck with the connection. Enjoy.
