Just BTD again. $7,200+ for business class seats for me and DW to Venice and then Cinque Terre for early 2025 - Lufthansa/United Polaris.
Airlines tickets are getting more expensive. Spent $5,100 on American Airlines business class on April-May 2024 of this year for Switzerland, Germany and Austrian trip. We tried Norse Air Premium seats to London (Sept-Oct. 2024) then EasyJet to Scotland. Norse Air (New York to London Gatwick) was cheaper and actually good, because their seats recline 45 degrees.
