While certain destinations may seem unattainable due to cost or flights, planning and bargain hunting can pull them into reach. Some of the countries with low flight costs that are expected to remain in 2020 include China, Japan and South Africa. If you’re more concerned with how much money you will spend while you’re on the ground in the country, consider Canada, Mexico, Cuba or Argentina for their advantageous exchange rates. If free or cheap outdoor travels are more your style, consider visiting Alaska, Costa Rica, Kyrgyzstan or Puerto Rico.
