Can I book one-way Business Class from Washington Dulles to Zurich?

Yes. Published one-way international Business Class fares are the trap: airlines routinely price a one-way at 70-100% of the round-trip, so travelers assume half-price and get quoted nearly double that. Through contracted consolidator inventory, a IAD-ZRH one-way typically quotes at roughly 55-65% of the round-trip band ($2,600-$3,400 round-trip on this route) - so always ask for the one-way quote instead of assuming the published number is the market. One-way requests are quoted the same way as round-trips: exact date, written quote, no card needed.

Should I fly direct or one-stop from Washington Dulles to Zurich?

Direct on SWISS Business + United Polaris is the cleanest path when available. One-stop alternatives via European or Middle East hubs occasionally price 10-20% below direct, especially in shoulder season. The trade-off is total transit time (typically 4-8 extra hours via connection) and the connection hub experience. For sleep-prioritized travelers, direct wins; for budget-prioritized travelers, one-stop is worth considering.
