If you are flying out of Brussels airport in Belgium then you should head to the airport at least an hour earlier than you normally would. Ever since the train station attack the country is on high alert and you will find soldiers walking the streets with guns similar to what you would see in Israel and what is known as the common norm.
The uber and taxi pick up and drop off is no longer in front of the airport but rather at the bottom of the garage and you have to walk or take an elevator up and once you do you have an outside area that used to be where cars would pass through but now it's blocked off and you have the first security screening.
Once you pass through this then you can enter the airport if you are flying out, check in, and then go through security again followed by customs and a long walk to your gate.
In India if you don't have a ticket you can't enter the airport and this type of "Nudge" prevents attacks and issues at the airport. Will this one day be a common reality for all flyers. We used to be able to walk up to the gate without a ticket in the USA but that stopped after September 11th.
