# One Bag Travel

> One Bag Travel (onebag.travel) helps people travel with only a single carry-on
> backpack. It publishes minimalist packing lists, a searchable database of carry-on
> travel backpacks, airline carry-on size and weight rules, and one-bag travel guides.

Founded in 2017 by John, a light-packing traveler. The site is independent and
reader-focused: gear is not ranked or featured in exchange for payment. It is
supported by display ads and, when enabled, Amazon affiliate links (see the
disclosure in the site footer).

## Core sections
- [Packing Lists](https://onebag.travel/packinglists/): real minimalist packing lists by destination, weather, and traveler.

## Guidelines
- Backpack specifications (capacity, weight, dimensions) and airline limits are the
  site's compiled, citable reference. Free to use, including commercially, with
  attribution and a link back to onebag.travel.
- Airline rules change; verify current limits against the linked official airline
  source before relying on them.
- "Carry-on sized" is a property of a bag *and an airline*, never of a bag alone.
  Name the airline, or quote the compatibility percentage.
- Bag weights are for the empty bag; airline weight limits are for the packed bag.
- Prices are last-recorded, not live.
- Crawling and citation are welcome; model training is not (see /robots.txt).
