Buses from Chicago to London Ontario?
Greyhound has service from downtown Chicago to downtown London,
Ontario. Adult fare is about $80 without any discounts. HOWEVER,
while Amtrak does not offer direct service from Chicago to London,
one may take the train from Chicago to Detroit ($27 - $48) and then
the Greyhound from Detroit to London ($25) or Robert Q from the
airport ($60). Costs less and the train leg is a much more
comfortable and preferable way to travel. www.amtrak.com
