the Airline Code doesnt work
They surely do, if you insert the correct codes.
also dispite the Airline codes am still not getting Swissport as my ground service still Aer lingus
That's because you set LUX and ZY, while the code for Swissport in GSX is _SWP.
The codes you enter there, must be chosen from an available GSX livery. You can check their actual codes by looking at the couatl.atc_parking_codes in the SIM.CFG of any GSX objects that comes in multiple liveries, like the FSDT_Baggage_Loader, for example.
