Dear All, I will be travelling back from Gokarna(south of Goa) to London. I am trying to split the journey by spending a few days in either Mumbai, Kochi or Bengaluru and then flying back to London. I'm sure some of you lovely travellers have done this. Which is recommended? I jus cant make up my mind!

Which has the cheapest/most convenient flights? Otherwise, I would pick Kochi, but my interests may not be yours.
