That makes no sense though, on any given day I might fly four flights with 186 pax which is 744 passengers moved on a single day with exposure to 4 takes offs, 4 landings and 4 lots of loading and ground handling as opposed to a 380 Pilot who moves 485 on a full flight with one take off and one landing and one lot of loading etc. The argument for more money based the more people means the A320/737 Pilot clearly should get paid more?
Problem with an Airline where the SO rank can get paid more than an FO or an FO as much as a Captain based on the Aircraft you fly is that it drives perverse outcomes in crew bidding, if all fleets were based on a single pay structure using rank and time in the company it would mean people would just bid for the flying they want as opposed to the most lucrative.
Still after the reign of Joyce we have a group that has multiple contracts, pay scales, opportunities based on nothing more than a desire to fracture employee groups and play them off against each other, in that he has been massively successful,
