> There is no intra-Europe flight as long as SF is to N [...] There are practically no wide-body intra-Europe flights, certainly none that serve any meals
That depends on how you define "Europe".
Europe-the-continent, Athens to Reykjavik is roughly the same distance as NY to SF.
If you define Europe as "Any territory belonging to a European country", then the longest domestic flight is between Paris and Saint-Denis, Réunion. It's about 9000 Km, which is twice the distance between NY and SF.
Tenerife is quite a popular destination, and is also relatively far from the mainland.
