In BOM you have a PA when arriving that takes you through a special line at arrival and helps you locate your bag and a PA when departing that takes you through security to the Lounge, which is very helpful as the queue for the 03.25 departure is always huge (lots of int flights at this time). The new Lounge (Oberoi) by the way has now alos a First Class section. Last saturday they had a mosquito attack there and only half of the Lounge was to be used because "too many mosquitos over there sir"....I had a lough until I started scratching all the bites....so be careful...
