1) AC is a sheep, not a shepherd. Keep dreaming.
2) Why would AC extend that to Es? Last time I was at the airport, it seemed like everyone had those fancy E35/E50/E75/SE100 Altitude tags.
3) I'm sure that such a chauffeur service is a high priority for AC, especially given its recent moves to introduce Rouge and the 77H.
4) They probably already do this for AC VIP. Of course, none of us regular folk would know about it.
