I flew New York to Paris on Air France in May of 2003, when they were offering the flights at a substantial discount (close to what a business class flight would cost). Besides the shortness of the flight due to supersonic speeds, it left quite early in the morning (around 7 am or so) which meant that it you were connecting in from somewhere else you needed to come in the night before – so only really convenient for those living or working in NYC.
Concorde at the gate.
I recall that the food and service were excellent (lobster omelettes with champagne, and attentive if very formal flight attendants). The seats were equivalent to domestic first class, seat pitch was around 38′’. Not much inside storage though, I remember the flight attendant had to take my backpack and store it somewhere so I did not have access during the flight. The ceiling is quite low, even in the middle of the aisle, so very tall passengers would have to stoop.
Looking across the aisle mid-flight.
But the view! Hard to describe but flying that high (around 56,000 feet) is noticeably different than flying a conventional passenger jet. Looking upwards the sky is a much deeper blue and if you looked closely you could see the curvature of the earth.
That view!
Once you got past takeoff and the run up to Mach 1 (which involved a fair amount of engine and wind noise) it was relatively quiet. On the Air France Concordes they had Mach Meters at the front of the cabin, so it was exciting to see it climb thru Mach 2.
A blurry view snapped from my seat as we passed thru Mach 2.
And after a short 3 1/2 hours you are done and landing at CDG. One note about the experience – if you were connecting at all the Concorde was not terribly convenient or the shortest time to get from point to point. The reason is that all the connecting flights at JFK, LHR and CDG are built around the normal arrival and departure times of normal transatlantic flights – I was very surprised when I booked my trip how difficult it was when going from SFO – Dublin to line up flights (I had to stay at JFK the night before to make it work).
