For example, book a flight on Norwegian Air, with the destination of Paris. The schedule includes a stop in Oslo. Normally, you’d stay on the plane for the hour or so it takes other travelers to exit and enter.

However, suppose the airline offered you a free night at an Oslo hotel, dinner and other goodies worth several hundred dollars? That’s the trend these days for some foreign airlines to get you to spend time and money in their home city. Would you, a senior with no particular reason to hurry, add a free day or two to the journey? When booking your next overseas flight with a stopover, ask if the airline offers this attractive freebee.
