You specifically say Europe as opposed to Spain. Would BA be an option for you? In addition to the bassinette, they also have oversized reclining seats from Britax that fit on the bassinette tray and take kids up to 2.
Downside is their 2-4-2 business class seating will see you scattered across the plane.
