We’ve made Open Jaw flight plans many times, which provided convenience and often saved some money. Not having to take a train, or to drive back to the original airport, saves on train ticket or rental car fuel prices. It also let us have an extra day in Europe, not having to backtrack to the original city.
Sometimes, though, just doing a round trip made good sense, if we were doing a circular trip on land anyway. Two trips in 2018 were like that. In April, we landed in Athens at night, slept that night in a hotel, and left on a ferry the next morning for an island. A couple days later, we returned to mainland Greece, rented a car, and drove a clockwise trip over the next 2 weeks, returning to Athens for our last 3 nights.
In September, we flew in to Dublin, and immediately departed on a bus for the western side of Ireland. We spent the next 3 weeks driving clockwise around Ireland to the north, than back down to Dublin, where we turned in the rental car and spent the last 3 days of the trip.
On an earlier trip to Ireland, we flew in and out of separate cities, and for a 2019 trip to Greece, we did Open Jaw as well, so it depends where you’re going, as well as the cost and the time required. Of course, every trip to Europe has left us with our mouths open in amazement at the beauty, the amusing history, the fun, the good people, the food, and the experiences, so in that way, we’ve had open jaws on every trip!
