We are planning a trip to Germany in April from Salt Lake City. As we are a Delta Hub, we have the most choices flying that airline. As I researched flights I noticed a trend this year. The Open Jaws flights (Stuttgart to Munich, Frankfurt to Munich, or in reverse) were a combined (for 2 of us) $500-$1000 more expensive than round trip to the same cities. The best bargain was round trip to Frankfurt and we have booked flights. We are flexible and can plan a good trip from/to wherever.
I was wondering if anyone else is experiencing the same with other airlines or other time frames? It might pay the airline to give a bargain to roundtrips if they find that too many people go in the same direction on open jaws itineraries. Maybe open jaws have become so popular that airlines just see an opportunity.
