Affiliate disclosure

Some links on this site to USFans and Kakobuy are affiliate links. If you sign up or place an order after clicking one, we may earn a commission from the agent. The commission is paid by the agent and does not add to your fees. We label affiliate links in articles and comparison tables. Our editors order and pay for test parcels with desk funds and keep the receipts. Commissions do not change the fees we report, the line-haul options we list or the scores we publish.
