ハワイアン航空はこのたび、東京の成田国際空港からシアトルへの直行便を新たに開設し、毎日運航することを発表しました。
豊かな緑に包まれたその景観から「エメラルド シティ」と呼ばれるシアトルは、美しい自然と現代的な快適さをともに楽しみたい人の旅行先として人気の都市です。
シアトルを象徴するタワー、スペース ニードルからの素晴らしい眺めを堪能し、パイク プレイス マーケットの知られざる魅力や誰もが知る見どころを探訪して、ケリー パークで一息ついたら、夕暮れ時の街並みを眺めましょう。ピュージェット湾でのホエールウォッチングもおすすめです。
シアトルの空港は米国国内線のハブ空港でもあるため、米国各地への旅もさらにスムーズになります。
