Ideas to make a long haul journey more comfortable

[Tigerpaws57]

Dd and bf are very excited to be heading off to NZ next month. I would like to gift them a little bag of treats to make their journey more comfortable and bearable. Have already got neck pillows, pack of cards and a couple of sudoko books. Any ideas for what else I can add?

Lip balm
Mints
Hand gel
Small pack of wipes

Pick and mix sweets. Its so nice to dig through a bag at intervals
Warm socks. My fave ones are merino as they don't smell, and then I hand wash them to use as my gym socks
Headphone doubler so they can watch a film together
I take a contigo cup with me and get it filled at the airport so I have nice coffee on the plane.

Some comfy clothes to change into for the flight - something similar to a track suit. small facial water spray (if you can take them on planes now) and moisturiser.

Small toothpaste (dentists often have samples) and/or small mouthwash.
Travel sized deodorant spray

Warm socks and a shawl, large scarf to use to snuggle.
