I am considering a stopover for a future trip from EWR to ARN possibly in Germany. Is this a good idea or is it generally more costly as opposed to booking two seperate reservations with possibly different airlines. Also what qualifies as a stopover? Are they just one night only. Thanks for your help and please excuse my ignorance on this topic.

Sometimes stopovers are free and sometimes there is a charge. Here is the fare rule for stopovers on a Lufthansa fare:

STOPOVERS

NO ENROUTE STOPOVERS ARE PERMITTED. A STOPOVER OCCURS WHEN THE PASSENGER DOES NOT DEPART AN INTERMEDIATE POINT WITHIN 24 HOURS.

Many airlines have a multi-segment choice, allowing a stopover for one or more nights, which may or may not be more expensive. You can check these on the airline sites or on Expedia, Orbitz, etc.

In general, I would try to make a rweservation with one airline.

Thanks for the replies. I will research it both ways. I don't know of anyone who has actually booked a stopover. Have never tried it myself but like the idea of it to save on travel time.

Maybe it's a "multi-city"? You can type in more then one destination. Generally more expensive then a simple round-trip, but you may be able to catch a sale. You never know.

Stopovers longer than 24 hours also usually result in somewhat higher prices due to airport taxes. It seems that if you stop over for less than 24 hours, then you're considered in transit. But a longer stopover attracts additional fees. Sometimes this isn't very much (e.g. 20-40 dollars), but in airports with high airport taxes built into prices (e.g. London Heathrow) it could add 100-200 dollars to your ticket cost.
