yes you can travel. I would suggest you take double decker as it takes less time and is comfortable.take diapers,wipes, clothes,water , something for you to eat.wear comfortable clothes and take shall or stole for covering

yes its safe as long as u take necessary precautions and maintain hygiene

you can travel... just keep the necessary things properly like diapers, wipes, some clothes on the top so that you can use when needed. keep <u>your</u> water bottles...wear comfy dress to breastfeed... you can also carry dupatta or something to cover and feed.
