I wish to travel from manchester to goa in february, any advice on the where i can find the cheapest flights?

Also is it advisable to stop over the night in mumbai?
Answer
I fly often, but mainly to america. i find the best and easiest way to get flights is on www.expedia.co.uk . as regards the stopover, i would suggest that you complete your traveling on the same day. the only time i ever stopover is when i am staying at the place for a couple of days because i wanna look round.
