If travelling by air...

If you are tavelling by air, make sure you put a pair of clothes in your hand luggage. It will be of help if the luggage you have checked-in goes missing.

An umbrella

Always carry an umbrella while travelling. Check with the weather before leaving.But an umbrella is compulsory.It comes handy in every weather condition, rain,snow or sun.

Extra shoes

Always remember to carry an extra pair of shoes. You can always get new ones( in case of trouble) but cannot feel comfortable in them and travelling involves a lot of walking.
