Bill,You can, indeed, do that. And you can make as many additional airlines as you wish that way.Then add the new carrier name and wav-file name in the aircraft.dat file. All the numbers after the wav name is for RC to reference if you've used that callsign before. You can leave them all 0, except for the last, which has to be 1. E.G.:GuardRail,guardrail,0, 0 , 0 , 0 , 1Airline Name, wavfile name, everything else 0, except for the last number.MAKE A BACKUP OF AIRCRAFT.DAT BEFORE MESSING WITH IT!

I for sure would be glad if an airline update with two swedish airlines SKYWAYS (callsign:Skyexpress)and MALM

Johan, you MUST email Doug with your request. Below is from his post above:>>New callsign requests should be emailed to [email protected]. New lists are borne from emails I get. Be sure to state how the callsign should be voiced, which isn't necessarily the tech correct callsign. I copy/paste requests to ensure you get exactly what you ask for. I do not always know what correct voicing should be. In the future, if you see callsign requests here on the forum, please direct the individual to email that callsign to me. That ensures none will be missed. Tkx!I'll add the callsigns from this string. Can't say with confidence additional requests will be honored if they're not found in my "In" box.Helps alot, tkx again!!Doug
