In no specific order.

• Charging station for electronics (can provide a link if you want)
• Our Phones for maps, Google Translate, and family contact
• Laptops for work and editing videos/Photos
• Noise-canceling headphones for loud planes, trains and workspaces (I prefer over-ear)
• We have AirTags in anything that will hold one just in case something walks off we can track it

We get Priority Pass as a CC perk and it makes long layovers or layovers in general a lot more comfortable.
