Cheapest seasonal fares for May/June are available from around $3250 roundtrip with early to mid-May departures. These require a 14-day minimum stay. For shorter stays, you can find fares from about $3300 - $3400. It's unlikely you will see fares lower than this price point. The cheapest fares require Sun-Wed departures and Tue-Fri returns with a 7-day minimum stay. For example, May 10th - 20th is $3364 roundtrip. For travel other days of the week (like Saturday departures and returns), the $3600 price point is probably the lowest you will see. All these fares have a 90-day advance purchase requirement which means they would need to be booked by mid-February for mid-May travel.
