Of course there are many things to pack for a trip.  You already know about all the usual things like shirts, pants, socks, etc.  However The Traveling Professor has some suggestions on packing things that are sometimes overlooked that can come in handy on an overseas trip. 

What to Pack on a Trip to Europe

Small Pair of Children's Scissors: 

This item has plenty of uses like cutting off stubborn luggage labels, removing wristbands, opening plastic packaging on items purchased at stores, tidying up frayed clothes and even cutting tape when packaging items to ship home.  You will wonder how you ever traveled without them.  Forget about packing a large, regular size pair of scissors, but in hundreds of flights, we have never had a pair of children's scissors confiscated.

Carabiner Clips: 

With these clips,  hand sanitiser, flashlights, luggage tags, scissors and more can be attached to the inside or outside of a backpack.  It makes these items easily accessible and hard to lose.

Big Colourful Luggage Tags:  

To be honest, we're really not too concerned about losing luggage, but since almost all luggage looks alike, we're more concerned about someone else mistakenly picking up the wrong luggage.  Putting recognisable luggage tags on bags makes it less likely someone will pick them up by mistake.

Bungee Cord:  

The Professor always has a bungee cord wrapped around his suitcase.  For the same reason as putting a big, fat colourful tag on luggage, a bungee cord can serve other useful purposes.  For instance, one time a zipper failed on a suitcase and the bungee cord was able to keep it reasonably closed.  When traveling with walking sticks that we are not able to fit inside a suitcase, The Professor was able to secure them to the outside of his suitcase with a bungee.  The Traveling Professor even used a bungee cord as a makeshift clothes line once.  Again, a bungee cord is something that probably won't be used, but when it is needed, it is really needed.

A Small Absorbent Micro fiber Towel:  

Wow!  The Professor has used this many times, especially in wet or misty weather in Normandy, Ireland, Scotland, and Iceland.  Dry off cameras, phones, glasses, fogged up windows and lots more.  Golf towels work really well because they usually have a grommet to attach the towel with a carabiner clip to your luggage or backpack.

Clear Plastic Baggies:  

The Traveling Professor takes about a half dozen plastic baggies on trips.  They are great for organizing and separating things like money (currency and coins), charging cords and adapters, meds, and all sorts of things.  If traveling outside in wet weather (again, like in places like Scotland, Ireland, Iceland, and Normandy) The Professor will always put documents and small electronic devices in the baggies.

Paper Binder Clamps:  

Perhaps no tool on this list has as many diversified uses as this one.  The Professor has used these clamps as a money clip, to hang clothes (on his bungee cord, of course), to keep papers/documents together, as a razor protector, to keep torn clothes and damaged shoes together, and keep bags of chips and other snacks closed, There are never-ending ways these clamps can be used.

Apple AirTags:  

An Apple AirTag is an electronic disk, about the size of a quarter.  With an iPhone, the AirTag can be tracked down to its exact location.  The Professor attaches them (with a carabiner, of course) to luggage.
