I recently found out about these travel companion programs. Basically, they let you have someone flight with you for free. The second person usually needs to pay the taxes and surcharges.
My question is which travel companion programs are the best? Have anyone used them? Is it easy to find eligible flights?
The answer probably depends on which airlines I fly with. Any US airline would be good for me. Also, I'd like to know if there's a decent travel companion program that can get me middle east from the US.
