I would like to encourage competition on routes since, IRL, at most airports you will see takeoffs by a variety of companies.
I'm not sure how the passenger demand is accounted for. It seems in market share there are many more flyers than the demand would indicate. For example demand might be 2828 but airline A is enplaning 2114 and airline B is enplaning 2039. Traffic is 4153 enplaned on a demand of 2828. Is this extra demand created by Airline B and his alliance?
I ask because it seems to me 2828 daily demand is enough to support at least 2 airlines but it's not clear which demand I should try to split. if I have 1414 seats as a reputable airline I should be covering my share of the demand. Is the actual demand the sum total of pax carried or are all the pax above demand connecting pax and always there for the airline in an alliance?
