Want to save both time and money on your next flight? You might want to consider something called the open-jaw ticket. What’s that?

Say you want to travel to London and France on the same trip. Instead of booking three separate flights, book two. Book one to London, then take the train to Paris and return from Paris.

It’s not only cheaper airfare — fewer government taxes and fees — but it’s also faster to take the train between London and Paris.

There are dozens of open-jaw ticket configurations out there and these tickets are easy to book.

If you’re online, check the multi-city box, not roundtrip, or just consult your travel agent or advisor.
