If You Try “Throwaway Ticketing”…
Be aware that most airlines prohibit “throwaway ticketing,” i.e., purchasing a more affordable round-trip airfare when you plan to use the ticket only for a one-way flight. If you try, airlines will often retroactively charge you the higher one-way fare and may even revoke your frequent-flier membership.
