L'avion's product is more for the premium leisure traverller to paris. IMHO.
As such it does reasonably well. You sleep fiarly well on the overnite to Europe. I pack some extra goodies from Bon Marche for the flight home. Sure beats steerage any day. And did you notice that the Prem Econ price is currently cheaper to paris than AF in steerage? At least for a quick hop during the Soldes d' Hiver.
