She flew WOW Air air, which has a decent carry-on size. Unfortunately, you'll never be able to operate in WOW air because the company ceased operations right after Rachel's trip.
What I love about this list is how minimalist it is. With such a small amount of clothing, you'll have to do laundry as part of your trip. For her journey, Rachel stayed at an Airbnb with a washer and dryer.
I love staying at Airbnb's instead of hotels because of how must more local they feel. Since AirBnB's tend to be more livable extra, they tend to have laundry machines right there inside the space. Super useful if you want to pack less and do your laundry on the way.
Rachel posted some thoughts on here list on Reddit. I'll summarize them here:
