Smala01,
do you have an in house agent? or us a particular agent? Might be worth them also speaking to the sales team at the airport. They have a dedicate person who deals with business travel and I am sure they would be interested in speaking with you, especially if you do have that many flight bookings. As CMR metioned, the airline could look at route deals etc dependant on the amount of travel you do! PM me if you want any more info.
Thanks
