I've added at the places I know of 100% sure that you can get on a freighter there a link to freighter travel. Ofcourse that is in no means a guide as to how get a fare, but at least it gives some consolation for people seeking means.
I would challenge the first sentence: "Freighter travel is a less crowded, cheaper alternative for crossing a sea or ocean, not using airplanes or commercial cruise ships or ferries." When I looked into this, it appeared to be considerably more expensive than air travel along similar routes.
For example, according to this page, Europe to USA by freighter travel would cost a couple of thousand dollars (20 day return journey at ~$100/day). Compare that to London - Washington, DC by air costing ~$600 return (United airlines, mid-week in May). 126.96.36.199 10:56, 2 April 2010 (EDT)
Freighter travel is more expensive than air but people should think of it as a holiday of so many days onboard a ship and the fare includes accommodation, meals and charges. In comparison to a land based holiday of lets say 10 days full board people will pay the same amount of money or may be more. Now if a Transat flight gets you to Europe for 5/8 hours and you pay 500 dollars return, a ship would give you the experience of a 10/15 day crossing for triple the amount, yes, but you will be well fed, well rested, etc... So think of it as a cheaper way to conventional cruise or land based holiday than to flying. It will never be considering the food and the accommodation you get not mentioning the experience... —The preceding comment was added by 188.8.131.52 (talk • contribs)
