Was at Chhatrapati Shivaji recently and shocked by the state of the place. I understand they are building a new terminal so this can't come quick enough. I was in transit with Jet Airways and found the experience painful. The extensive queues are extremely long and the security checking inconsistent. We found that duty free was being confiscated at random. Some people getting through with liquids galore. In some cases they were even confiscating dry products. What then shocked me is the fact that the airport operates like some seedy back alley part of Mumbai. Being a smoker I asked official staff where to smoke and was first pointed to the toilet. Confused I then asked another member of staff and was further escorted to a janitor's closet where the janitor was waiting and said: "five dollar you smoke here" - in a storage cupboard! Not convinced I then asked somebody else and was pointed to the restaurant likewise where they are charging passengers to smoke illicitly in a storage room. I refused of course. BOM is a non smoking airport no matter what they tell you or where they lead you. At one point paying for duty free took 15 minutes no reason just lots of paper work fiddling around with my documents and so on. It was all very suspicious. Finally we ordered some KFC at the counter having contracted Delhi Belly on the outward journey - thinking that deep fried chicken would be the most sanitary option. While we waited for food an 8 inch long rat jumped onto the counter chased by a member of staff - ran along the counter over the cash desk and up a wall. This was much to the amusement of the staff who gladly went on serving food without even washing their hands. In summary BOM is not a good option for transiting which is a shame since India now boasts a couple of good airlines offering attractive transit deals. I will be avoiding them personally.
