I'd probably do the same because of the fare. Unfortunately, all of these airlines have a tight 31-inch pitch in coach. KLM have old planes without personal entertainment systems, but the inflight service is good, and although it involves a connection Schiphol is good for shopping. If it didn't cost substantially more I'd otherwise have picked the AF metal (after having checked the fine print that you'd actually get mileage credti), because it's non-stop, in a new aircraft with personal entertainment system, with superior food and free champagne...
