All the concierge group at YYC are great. I cannot single out any one as being better as I have dealt with all of them over time and found them to be the best group of people I have dealt with in the airline area. The ones at other areas are extremely efficient and helpful as well but most of my dealings is with YYC. They are very helpful in all aspects and have never told me they cannot do something. And I have asked for a lot at times. I think their motto is Ask and Ye shall receive. Great group and one of the best services that AC provides. Now I hope RM doesn't find this as a deviation from the norm and delete them. 2 of them at YYC are on a prolonged leave but due back soon.
