Route notes
Why this routing works
This multi-stop itinerary uses Washington DC as both the origin and endpoint, with a short domestic stop in Houston before crossing to Europe. The routing keeps the longest flying in the middle of the trip, which can make the pacing more straightforward than starting with back-to-back international sectors.
At three weeks total, the stop lengths are clearly defined: 4 nights in Houston, 6 nights in Ibiza, and 8 nights in Naples. That creates a simple progression from a brief U.S. stop to two longer European stays, with the longest stop placed last before the return to Washington DC.
As a single economy multi-stop ticket, this kind of routing is useful for travelers who want fixed sequencing across both North America and Europe without building separate one-way bookings. Departing in July places the itinerary in the Jul-Sep travel window, so the schedule is oriented around peak summer timing rather than shoulder-season flexibility.
