I was upgraded to Voyageur Premiere on my flight from JFK to Paris on May 14 – while booking I had looked at the price difference between the premier and regular coach fares and I am glad I did not waste my money.
The extra leg room and slightly wider seat were nice, but for some reason the seat was very uncomfortable. The “recline” primarily consisted of the seat bottom sliding forward, but the seat back itself did not go back that far. The leg rest was a joke – it did not extend out enough to even make use of it. My back hurt in the fully reclined position so I used my pillow as a lumbar support.
The service was no better than voyageur class, and in fact had declined since the last time I flew Air France. If I get upgraded again I won’t turn it down, but I would never pay extra.
