I am releasing the codeshare module that will show all flights in your schedules that you are codesharing on. You are able to include an image of the airline, to do so you must change the img link in the codeshare.tpl file. change the skin_name to your skin name.
This modules uses a modified simpilots events module admin side.
I have released version 1.2 of the module. It adds the ability to add the flight to your bids directly from the module. You can download it from my github page. https://github.com/Strider2/codeshare
when adding the image, it just needs the code of the airline, just put the airline code in, do not add the image type. In the images folder, the image must be named the same as the airline code like BAW for British Airways that should be BAW.png.
Thanks Strider for your module and your answer but I have added Other VA airline in my Airlines List ex: (HEW) but not is normal if one pilot need to register he can see others VA list.
By that way I mean If i want make a code share with others VA the flight number I give need to match with the other VA ICAO.
